We're hiring for the following openings:

* Engineering Program Lead

* Backend Software Engineer

* Quantitative Modelling Engineer

* Bayesian Software Engineer

* Program Synthesis Engineer

* Analytic Learning Algorithm Researcher

* Product Managers and Business Development

* Domain Experts - Valuation, Quantitative Default-Probability, or Interest Rate Prediction Models: to collaborate on use cases, from opportunity validation through production

We’ve recently released a series of recordings from one of our quarterly team retreats, to share a look into how we work, and some of the technical problems we’re solving. A few team members sat down and talked through these topics, unscripted, and real. If you consider applying to join us, they offer a glimpse into our culture, and what working with us is really like.

Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time

I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team.

It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people.

This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot.

You can apply at https://job-boards.greenhouse.io/wikimedia/jobs/8140060?gh_s... - we don’t auto-filter based on AI or anything like that, I will personally see your resume.

Working for Wikimedia would make me actually consider moving back to the USA for the opportunity.(I'm in Japan for reference.) I previous contributed to Mediawiki and the extensions ecosystem for about a decade.

I‘ve been considering applying at WikiMedia for a while now, but [my country] is not in the listed countries. Is there a chance you‘ll expand this list in the future?

Ah, that is too bad. It's certainly always possible the countries list could expand in future, but it's not something I have insight into and unfortunately can't give you too much to go on.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings, starting with bricklaying.

There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.

We're looking for experienced software engineers for many roles. You can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Modelling buildings in code and finding the right UI for operators to edit them

- Designing systems for robots to drive safely and fully autonomously around a building site

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

*Fastly | Software Engineers (Senior, Staff, Principal) | US, UK, EU, APAC ONSITE PREFERRED | Full-time*

When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.

We're a global edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.

We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.

Onsite preferred, but remote candidates with a strong fit are welcome!

Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.

* The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services. * Apply: https://www.fastly.com/about/careers

Hey there! Just sent an application for the Software Development Engineer role to which I believe I have a lot of overlap with. App under roro[dot]chaudhary[at]gmail.com. Any other questions, feel free to let me know!

https://linkedin.com/in/rorochaudhary

What are the EU roles you specify here? career page is position specific and not broad like you seem to suggest

Yeah The Who's hiring format isn't a perfect fit for how we have it structured. In general, engineering can hire remote first if there's a good fit, and we have local entities or EOR processes for every EU country (to the best of my understanding)

Going through the engineering job posts but they seem to be all in the US. I'm the main maintainer of a popular OSS project using WebAssembly and want to stay in this area (OSS, C, WASM etc.). Looking at "Staff Engineer - Edge Protocols" because of the good overlap with my latest experience. Is this available in Europe as well?

Spanish National Cancer Research Centre (CNIO) | Madrid, Spain | HYBRID | Senior Scientific Computing Engineer | Full-time

CNIO is one of Europe's leading cancer research centres. We're looking for a senior scientific computing engineer to join the IT, Scientific Computing and AI area and take ownership of the infrastructure behind our research, from genomics pipelines to AI models. You'll be the senior scientific computing person in the area, reporting directly to me (the area head), and you'll help define where scientific computing at CNIO goes over the next few years.

What you'll do:

- Shape the roadmap for scientific computing at the centre and drive it forward

- Own and evolve our HPC cluster (Slurm): scheduling, monitoring, capacity planning, user support

- Build out our GPU / AI infrastructure as the centre's ML workloads grow

- Work with researchers to turn their analyses into robust, reproducible pipelines and tools

- Optional: co-author research papers

What we're looking for:

- Several years running Linux HPC environments in production (Slurm or similar)

- Comfortable with automation (Ansible, Python), containers (Apptainer/Docker) and workflow managers (Nextflow, Snakemake or similar)

- Someone who wants to set direction, not just keep the lights on

- Bonus: Ceph, Kubernetes, GPU stacks, a bioinformatics background

- Spanish not required

If interested: tdidomenico-at-cnio-dot-es.

Discord | Senior Software Engineer, Application Security | San Francisco, CA | ONSITE | $280K–$330K TC

Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.

We're hiring a Senior Application Security Engineer to join the Product Security team. Responsibilities include threat modeling and secure design review with product and platform teams, building and improving AppSec tooling (SAST/DAST/dependency scanning), and working directly with engineering teams to remediate findings.

Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.

Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and reviewing code across languages, and sound judgment on prioritizing real risk over checklist security.

Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.

Apply: https://job-boards.greenhouse.io/discord/jobs/8656854002

Tufalabs | Zurich, ONSITE | Full-time | 100-200k CHF | https://tufalabs.ai/

(I want to preface that we don't have a ton of budget to expand our team right now and we want to keep the team small, but I also don't want to miss someone who would be a great fit)

We are a self-funded independent AI research lab in Zurich. Currently we explore ARC-AGI3, LLM/RL reasoning, and quant. We recently started a new LLM post-training and pre-training effort, led by some ex-engineers from the swissAI Apertus team. We also like to do some Kaggle on the side, our team includes the top #3 and #12 globally.

Our overall roadmap is to catch up with LLM capabilities, own the full stack, and use it to do our own independent research, pushing efficiency and looking for new paradigms. We expect our new cluster (2x NVL GB300) to be up by the end of the month.

Long term we want to switch to AI alignment/safety research as I believe this is all that matters when AI capability is high enough.

We look for people who are driven, who believe it's possible to make significant contributions to both AI capabilities and safety, and with previous experience pre-training and post-training LLMs and related infra.

If interested, email me at benjamin at tufalabs ai.

Statecraft | Forward Deployed Engineer (All Levels) | REMOTE (US) | $160-220k + equity

At Statecraft, we are building an AI workforce to help automate the US government. Currently our government is operated almost entirely by consultants who outnumber public servants 3:1 and institutionalize inefficiency so they can bill more hours. This only leads to agencies struggling to meet their missions, overworked and underpaid public servants, and overburdened taxpayers.

Most of what these consultants do is easily automatable: data entry, basic spreadsheet work, filling out paperwork, etc.; we do this with AI and save taxpayers ~80% on average while completing the work ~10x faster with 2-3x less errors.

We're a small, lean, mission-driven team and hiring Forward Deployed Engineers to build use cases and integrate deeply with agency customers. You'll be working with critical systems, massive surface area and national impact.

* This position requires U.S. citizenship and the ability to obtain/maintain a security clearance.

Snout https://snout.com/ | Multiple Engineering + Product Roles | Remote US or Ontario, Canada | Full Time

Join us at Snout on our mission to ensure no one ever has to make a health decision for their pet based on the cash in their bank account. Snout plans pay for 100% of routine veterinary care, unlimited visits, and additional member benefits - think pet insurance, that you will actually use every year.

We're growing the team and hiring across the board. Open roles:

Full-Stack Software Engineer - Build and ship every day across our web apps, payments, and data systems, from database to UI.

Across all roles we're looking for at least three years of relevant experience, and we're hiring senior and staff level engineers as well.

Our tech stack includes Node.js, React, PostgreSQL, AWS, Tailwind, and Python. We use both JavaScript and TypeScript heavily. Our team uses LLM-based tooling day to day, but we're fundamentally a human-centric team, and our product itself does not heavily feature AI components.

Apply at https://jobs.gem.com/snoutd

Looks like they have an accidental “d” at the end of the link.

Remove that and you get https://jobs.gem.com/snout

I imagine it was a mitigation measure against botspam slopping it up in Snout's candidate pool.

Or maybe a typo, still, I'd have left the link unstated.

...Internet courtesy is weird these days :/

> a mitigation measure against botspam slopping it up

I find it hard to imagine that would be the case. They already link to the same page from their website without any typos, and they link to their website from the comment here.

Apex Space | Multiple Roles | Full-Time | Onsite | Los Angeles, CA | apexspace.com

Apex Space is building standardized spacecraft platforms to enable true mass-production of spacecraft and enabling getting varied and similarly mass-produced payloads to orbit.

We're hiring everything from technicians to product/project managers and supply chain to all sorts of engineers: thermal, mechanical, mechanisms, solar, optical, power systems, electronics/avionics, PCB, embedded software, ground software, devops, and more.

NOTE: Due to federal law, you must be a US person (citizen, green card holder, some other classifications) to work at Apex Space. Please state your residency or citizenship status in your email. If you are not a US person, I can't help you.

I think I'd be a strong fit for some of your roles, but the benefits advertised read to me like the absolute bare minimum to meet industry norms. Is there anything you would say is a real advantage for Apex?

Trustworthy Technology | Earth | Part Time | REMOTE | Vision, Marketing, and/or Design

Hi, we are a small group trying to bring the "trustworthy" feature back to tech. Curating and building a FOSS+ toolset, storefront, and eventually online service—all to support freedom, privacy, and informed consent—on device and on the net.

We've written our thoughts and research down at: https://trustworthy.technology/ and we have a few geeks starting projects at: https://codeberg.org/aol

First off, you'll notice that you've not heard about this project before. Next, the message is a bit scattered, and the "programmer art," while arguably not horrible isn't winning any awards either, haha.

That's where you come in.

You are one of the few folks who really cares about this stuff, and also a graphic/product designer, or perhaps a digital marketer, communicator or "people whisperer." (Being in the EU would be helpful as well, to work from the digital sovereignty angle, though not required.)

Some of us are unemployed and currently donating our time. Maybe you are too, or retired/cashed-out and bored. Consider this another FOSS-like project. We hope the store/service will make money, but we're not there yet.

Interested? Let's chat at: https://trustytech.zulipchat.com/join/h5usqnt2bet7exz747cbf3...

BTW, if/when you join please say hi let us know what kind of projects you're interested in.

Ours Privacy | Senior Platform Engineer | Remote (US) | Full-time | https://oursprivacy.com/careers

We're building the marketing infrastructure healthcare has been missing — a privacy-first CDP and consent management platform in one product, so healthcare marketers can run real campaigns without putting patient data where it doesn't belong.

You'd own our AWS platform end to end: Lambda, Kinesis, SQS, Fargate, DynamoDB. High-volume event pipelines feeding dozens of third-party destinations, where correctness actually matters. The work is infrastructure-as-code, pipeline reliability (retries, idempotency, DLQs, backpressure), CI/CD and developer experience, and the observability and controls behind our HIPAA and SOC 2 posture.

Small team, large surface area, real latitude to fix what you find. TypeScript/Node throughout. 5–8 years experience, deep AWS, and you've debugged a streaming system under load.

Email careers@oursprivacy.com, subject "Senior Platform Engineer." I read every one.

Renaissance Philanthropy | Research Engineer (Speech AI/ML) | Remote (worldwide)

Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments.

RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years.

We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student.

We're looking for folks who:

- have built and operated production ASR or speech-processing systems

- know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment

- can speak the languages of both research and engineering

- want to help create a world where all children learn to read well.

If this sounds like you, please apply!

Catalyst·Wayfare AI | Agent Builder | Remote (US ET Overlap) | Full-time / Part-time / Contract | https://catalystwayfare.ai/careers

AI transformation firm shipping production AI systems for mid-market enterprises in regulated and technical domains — finance, energy, industrials, healthcare. We do not stop at PowerPoint AI strategy. We ship working systems alongside our clients' engineering teams. Small teams, deep expertise, real autonomy on real work.

Hiring: AI Engineer, Agent Builder — Hands-on builder delivering key projects within multi-agent orchestrations — initially for one of the country's leading power engineering firms. End-to-end ownership of individual capability agents — prompts, tools, retrieval, deterministic checks, evals, monitoring, enabling infrastructure setup. 3–5+ yrs strong Python, real production LLM API experience, shipped multiple agentic systems end-to-end. 1099 contract, ~20–40 hrs/wk. Occasional US travel, where feasible. International candidates will be considered subject to US ET time-zone overlap. https://catalystwayfare.ai/jd-builder

Apply: per the JD's instructions, to talent+hn@cwai.co. Short cover note and impressive repos matter more than a resume.

Cider Consulting | NY, USA | REMOTE (US-based only)

We’ve built custom software for US clients since 2018, and we’re now building a different delivery model: one senior engineer-consultant owns the whole engagement end-to-end — from figuring out the problem with the client and shaping the AI solution to building and getting it into production.

Hiring: Forward Deployed Engineer. Must-have experience: - pre-sale/discovery experience — you personally ran early client conversations before any scope/contract existed, without a PM/PO/BA layer; - direct hot-lead communication; - solo consultant role (not pure engineer); - English C1-C2; - 5+ years of production full-stack expertise (commerce) with at least one of cloud infrastructure, CI/CD, or data; - shipped AI-powered features to production used by real external end users (not model training/fine-tuning, not courses, not side projects with no end users).

In your application, name one specific engagement where you led discovery before a contract existed, and one AI feature you shipped with real users — vague descriptions won't be reviewed.

Lumen Labs | Robotics / Hardware Engineer | San Francisco, CA | ONSITE | Full-time | $130k–200k + equity | https://lumenresearch.co

I'm Daniel, co-founder. Lumen Labs is building the cognitive layer for physical AI. Nearly every major robotics effort today teaches machines by showing them thousands of hours of human teleoperation. We think that paradigm has a ceiling, and we're working on nature-inspired architectures for unstructured environments (construction sites, mining, pipelines, battlefield). Pre-seed, backed by top VC funds and operators from robotics/AI companies.

We're a team of two and hiring teammate #3 to own the hardware and infrastructure that keeps our research platforms running: the ROS2 (Humble) stack across onboard and offboard compute, sensor integration and calibration (LiDAR, depth, IMU, encoders), the safety pipeline during autonomous runs, and getting trained policies onto real hardware. Today that's wheeled navigation; we're dipping our toes into drones and eyeing weirder platforms like pipeline inspection. Where we're at: zero-shot sim2real transfer with a policy that runs at 100Hz on an ESP32 and took under a day to train.

You: hands-on with real mobile robots (UART, encoders, PWM, IMU, LiDAR), strong Python + embedded, comfortable reading code you didn't write, and can debug hardware and firmware at the same time. If "full-stack" to you means firmware, a multimeter, and a ROS node in the same afternoon, you'll fit right in. Visa/relocation support for the right person.

Full posting: https://desert-bearskin-26d.notion.site/Robotics-Engineer-Ro...

Email hi@lumenresearch.co, mention HN, and tell us about a project you've built. If you can link to a time you got a trained policy running on real hardware, you go to the top of the pile.

NetBird | Berlin, Germany (or remote, CET/CEST overlap) | Full-time https://netbird.io/careers

NetBird is open source networking and access control WireGuard-based overlay networks with zero-config peer-to-peer connectivity. Open source, built in Europe, used by thousands of teams worldwide. We're a small and growing team going up against the incumbents in network security. Post Series A.

- Engineering Manager : You will take a huge part in leading and scaling our engineering org. Unblocking, scaling, hiring, you'll still read code and hold technical opinions that impact the product. We're not looking for a pure people manager. Networking/infra background is a plus, not a filter. If you've scaled a team from 0 to 20+ and seen your product scale too, I'd love to talk to you.

- Senior/Staff Backend Engineer (Golang) : the control plane: peer coordination, policy and access control, multi-tenancy, and keeping it all fast as customer networks grow into the hundreds of thousands of peers.

- Network / Client Engineer (Golang) — the agent side: WireGuard, NAT traversal and hole punching, relays, DNS, and shipping one client across Linux, macOS, Windows, iOS and Android. If you enjoy debugging why one connection out of a thousand won't go peer-to-peer, this is the role.

- Solutions Engineer — technical, customer-facing, pre/post-sales. You'll be the person who architects a rollout for a 500-person company's network live on a call, and a great channel back into the roadmap.

We have an office in Berlin and mostly work CET/CEST. We'd love to have you in the office with us, but if your experience is stellar we're happy to hire remote. We're scaling quickly, so this is a chance to join early and scale your career as well as with the company.

Apply at https://netbird.io/careers, please mention you found us on Hacker News in your application.

This is really interesting work! I just sent in an application, hope to hear back soon

Cascade Space | Senior Mechanical Engineer | San Francisco, CA (ONSITE) | Full-time | $150k - $190k + equity

Cascade Space is building ground-based infrastructure to support missions to the moon and beyond. Instead of single large dishes, we're building arrays of dishes combined with a digital beamformer into one large aperture — comparable to a NASA Deep Space Network 34m dish. We raised our seed round last year and this is our first mechanical engineering hire.

You'll own mechanical integration of vendor dish systems with our in-house RF hardware (feeds, LNAs, amplifiers): packaging for ultra-low-noise electronics that has to survive outdoor conditions, alignment/tolerance strategy, and structural/environmental testing. When it's time to stand up our first array, you'll be on-site for deployment and commissioning. Full arc from CAD to field install.

Looking for 4+ years designing and deploying complex hardware systems, experience integrating electronics into outdoor/exposed environments, thermal management of sensitive electronics, precision mechanical assemblies, and owning vendor/fab-shop relationships. RF/antenna experience is a bonus, not required.

Note: US Persons only (ITAR/EAR — some customer datasets are restricted).

Apex Dental Partners | Full-Stack Developer | Dallas, TX | REMOTE (US) or HYBRID | Full-time | apexdp.com

We're a Dental Support Organization running 65 practices across eight states. Dentistry doesn't sound like a technical job, but the platform behind it is: we've built our own operations system (Rails 8 + React, Electron, Go, and C#/.NET against OpenDental, all on AWS) and we're pushing hard on automation and AI to make the practices run better.

The team is small and developers own problems end-to-end. You'll figure out why a billing workflow breaks down, design the fix, ship it, and hear from the office manager who uses it the next week. Recent work includes an AI-first metrics layer that answers operational questions in chat, automated patient scheduling and communication, insurance verification scraping, and a live PMS integration across every practice. The domain is wide (clinical workflows, payroll, patient comms, revenue cycle) and there's a lot of novel work left once you learn the business. Big emphasis placed on being able to sit down with non-engineering team members and understand their workflows and build software to make it better.

Good fit if you want a stable company, a small team, broad latitude, and work that visibly matters to the people using it. We're actively building new features, not just maintaining what exists, so there's a healthy mix of greenfield work and improving a platform that's already in daily use by our nearly 1,000 employees.

Must reside in the US and be authorized to work in the US without sponsorship.

Tecuity | Senior Software Engineer I | Hyde Park, UT (ONSITE preferred; will consider candidates who can commute in 1-2x/month) | Full-time | $90k-$135k

Tecuity has spent 20+ years building software for Secretary of State offices — state government agencies handling business filings and public records. Real filing deadlines, statutory requirements, and citizens who depend on the system working.

We're hiring a Senior Software Engineer I to own features end-to-end on a mature, multi-tenant .NET platform, typically supporting more than one client implementation at a time, each with its own database and release calendar.

Stack: C# / .NET 8 & .NET 10, ASP.NET Core, Web API, Entity Framework Core, MS SQL Server (heavy stored-procedure work), React + Redux front end, Git/PR workflow, Azure DevOps CI/CD.

AI-assisted development (Claude Code) is a standard, daily part of our engineers' workflow here, not a pilot program — you'll be expected to use it well and verify its output rather than just accept it.

Looking for 6+ years professional experience in C#/.NET and SQL Server. Government, regulated, or compliance-driven software experience is a plus.

Ideally we're looking for candidates who can work onsite from our Hyde Park, UT office, but we're open to Utah or Idaho candidates who can commute in once or twice a month for the right fit.

3C Digital Solutions | Terraform Module Developer (Infrastructure as Code) | REMOTE (US) | Full-time | https://jobs.curriculo.me/3c-digital/job/a14f0ded-8f8f-49ad-...

We're a small IT consulting firm working in federal and other regulated environments. We're building a reusable Terraform module catalog: versioned, tested, documented modules published to a registry that other teams consume, across cloud, container, and virtualization environments. Module and platform engineering, not one-off deployments.

You'd own the standards: module interfaces, validation, testing, releases, deprecation. Small team, no layers, and real influence over how we build. Growing, with room to move into broader platform ownership or technical leadership.

Looking for someone who has built and maintained a shared module library other teams actually used. Semantic versioning, automated testing, input validation, policy compliance checks, CI gates. Production experience with AWS, Azure, GCP, or OCI.

Multiple positions. US citizenship required (federal contract). No visa sponsorship.

At SmallSat last month, a supplier walked up to me (in a full spacesuit costume), said "oh you're from Silkline, we love you guys!" and handed us a roadmap item on the spot. That's the job: sit with customers, hear what's broken, ship it. 0-1 product, real UI/UX ownership, ERP integrations that sync POs and manufacturing data.

Stack: TypeScript, React, Next.js, GraphQL, Trigger.dev. You: 5+ years full-stack, startup or 0-1 experience, fast with APIs (bonus: ERPs). The role touches ITAR-controlled data, so US persons only, no visa sponsorship.

We 5x'd our customer base this past year and continue to grow fast. Small team, direct line to the founders (Isaac and myself). Also: space-suited mascot named Silky.

Puma.tech | Remote-first with PST overlap | iOS/MacOS, Android, Ai/ML, Growth | https://puma.tech

Hi all, I’m Yuriy, founder of Puma.tech. Prev. worked at Cloudant (YC S08), Meteor (YC S11), Parse (YC S11, Facebook/Meta), and explored AI/ML (computer vision for self-driving cars).

We have 2 products:

1. https://PumaBrowser.com: iOS & Android mobile browser with built in LLMs & wallets. 1m+ downloads.

2. https://PumaAI.com: small research lab focused on building private local/hybrid alternative to ChatGPT.

Open Roles: Eng (iOS/MacOS, Android, Ai/ML, Browser Extensions), Based Social Media Intern; Internships: Eng, Design, Growth

We’ve raised a few rounds from some of the best builders in ai and crypto:

Protocol Labs (YC S14), Chris Larsen (Ripple), Anatoly Yakovenko (Solana), Illia Polosukhin (NEAR Protocol), Sridhar Ramaswamy (Snowflake CEO), Jason Warner (poolside.ai, ex-GitHub CTO), Don Ho (Orange DAO, Quantstamp W18), Evil Rabbit (Vercel), John Phamous (SF Compute) and other amazing builders.

How to Apply: email careers+hn [at] puma.tech with your GitHub, a note on what you're most proud of building and what you'd like to build next.

Thank you!

Applied 2 months ago. No response

apologies, we've got a lot of ai-generated applications in the last few months so might have missed it. mind bumping the thread and mention `html5cat` and i'll make sure we look into it?

thank you!

found your thread – your email covers things you did, but nothing about "why Puma" or other simple questions we ask. seems like one sided, generic mass application. impressive background, but didn't seem like you care about what we're building.

I guess you found the wrong thread.

1. I received a question about my schedule (meaning: no other questions asked), I answered and received no further response. 2. I applied using your own template {a note on what you're most proud of building and what you'd like to build next}. My application was absolutely not generic mass application 3. I sent you several things I’m proud of. Among them were:

- A Product I build (independently) - linkkraft browser that captures pages/resources using chrome devtools protocol & other electron network API), basicly local-first browser. https://arestov.github.io/linkkraft-notes/trails-tree-plus-o... You are "building private, local AI in browser". This seemed specifically relevant, escpecialy if you are building a browser agent, not just a chat (like aside https://aside.com/blog/how-we-built-the-sota-browser-agent-t...).

- my open source contributions to p2p (torrent network) libraries. I did this because you have IPFS (which is p2p network) in browser.

Your application template does not contain "why Puma?" question, but spending my own time on these 2 things (local-first browser, p2p) and including them in the application was, I believe, a pretty clear answer to it.

I do appreciate you responding directly.

try counting how many "I"/"my" you have even in just this comment compared to "team" or "Puma" or "users/customers".

instead of bumping the email thread you decide to put this all publicly. ok. but if you want to be pedantic, our HN post includes "what you'd like to build next?" which you conveniently skipped.

if you read our website, the application there includes "Why I’m interested to join Puma?".

you seem to care much more about being right than making progress or being helpful. i hope you change your approach since you clearly can build things.

Same here, sent and email 3 times across the last 2 years, no reply

your first two application were generic and ignored the few basic questions that we ask in the posting, thus subsequent one didn't get reviewed

I applied in February, included answers to your questions, my email was not generic - it was fully handwritten for your post, it only talked about things relevant to Puma, and included a CV. I received no response either.

I'll be honest, it's not looking good for you

Which of these two are not generic? There's dozens you spammed us and other startup founders with. Some are just empty emails with just CV. None were sent in Feb fyi.

"I have attached my resume in response to your posting. I am interested in interviewing ASAP."

"Good afternoon, I saw your post on HackerNews and I am interested in interviewing. Best, Brian"

I'm not Brian. I also doubt Jose or Gleb were Brian. You're talking to another person now. I am the third person who replied to you in this thread. My friend, should you be hiring people if you get lost in a chat thread?

thanks Gmail for Google Workspace for pulling Brian's threads when searched for `boltzmann-brain`.

but yeah, if you bump the thread with `html5cat` mentioned i'll personally look into it – my goal is to respond to every earnestly submitted application despite the sea of AI slop.

update: found your email – definitely well written but didn't have GitHub so it got skipped.

doubtful you've found the right email, but it's ok - the extent to which you're repeatedly confused about basic facts shows I'd hate having someone like that decide about my ongoing employment.

I applied, please look into my application once you get the chance

Obi9 | Full-Stack Engineer | REMOTE (US time zones) | Contract or Full-time | https://obi9.ai/jobs/full-stack-engineer

A hedge fund analyst covering therapeutics has to watch hundreds of companies at once: press releases, SEC filings, management calls, updates on government sites, clinical data publications. Obi9 ingests all of it and surface what matters. Hedge funds pay for it today.

We are early and the team is small, so you would own entire surfaces of the product rather than pick up tickets:

- Ship full-stack features end to end, from the data model to the interface.

- Build the ingestion and enrichment pipelines that turn raw data into rich insights and alerts.

- Work on AI-backed features, from ideation to serving them in the webapp and over MCP.

- Make heavy data legible: dense tables, financial charts, document viewers, a live alert stream.

Stack: React + TypeScript, Node, Elixir, Python, distributed AI pipelines.

Beyond full-stack ability we want someone who already understands one of these worlds. One is enough, we are not asking for all four:

- Financial information systems. Bloomberg, FactSet, AlphaSense, Capital IQ, PitchBook. You know what entity resolution, identifier mapping and point-in-time data cost to get right.

- Financial domain knowledge in healthcare. Equity research, valuation, or time spent living inside filings and models.

- Audio and transcription. OtterAI Deepgram, AssemblyAI, Whisper. Diarization, speaker attribution, turning messy call audio into something quotable.

- AI-intensive products where the pipeline IS the product. Legal AI, document intelligence, medical coding. You know what evals, grounding and extraction schemas that hold actually cost.

Minimum: 5+ years building production web applications, a technical degree, fluency with current AI tooling, and eight continuous hours inside the 8:30am to 5:00pm ET window.

Apply: https://obi9.ai/jobs/full-stack-engineer?tab=apply

- Contribute from wherever you like; we are fully remote

- Set your own time commitment, as long as it's at least 30h per week

- See how we work in our handbook: github.com/reef-technologies/handbook

- Influence the way we operate through our Sociocracy 3.0 decision-making process

Salary on a B2B contract:

- 45-70 USD or 180-280 PLN per hour

- Flexible work schedule (as measured with a time tracker)

- We automatically adjust rates based on inflation twice a year

We're looking for someone with 5+ years of programming experience, including at least a year with Python (including open-source and significant personal projects).

A brilliant entry! it’s a shame I was just a bit short on the age requirement. 4 instead of 5. It would have been interesting to take the tests – I reckon they’d have been quite cool, given the design of the entry and the fact that I’d made it through to the test stage!

Steg.AI | Machine Learning Engineer | Irvine, CA (Onsite) | Full Time

Steg.AI develops AI-powered watermarking technology to protect and authenticate digital media. Our invisible watermarks are imperceptible to humans but robustly detectable by our proprietary models. Founded in 2019, we're an NSF- and investor-backed startup in Orange County, CA, with a team of 6 PhDs in computer vision.

We're hiring a Machine Learning Engineer to help push the frontier of AI for watermarking, steganography, and media provenance. You'll take state-of-the-art steganography models and own their journey to production — optimizing and deploying them on desktop and cloud platforms, serving as the link between research and customer-facing products.

Responsibilities: productionize novel steganography models, build inference pipelines, integrate models into cloud platforms, benchmark performance, and turn research into maintainable production code.

Required: PyTorch, ONNX export, experience deploying deep learning models to the cloud, Python and C/C++, strong cross-team communication.

Bonus: background in steganography/watermarking/media provenance, video/image codecs, MLOps tooling, CV/ML publications or open-source contributions.

To apply, send your resume to careers@steg.ai

Quill | Fullstack SWE | Full-time | Remote, PT/ET hours preferred | $150 - 210K USD + equity | https://quill.co/

I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).

Some examples of how customers get value from Quill: • pre-IPO fintech adds custom reporting & data export features to their money movement product. • Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard. • Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.

Reasons you’d love working with us: • Work with a small, focused, talented team on a highly technical product (by developers for developers). • Funded company in a big market, but still prelaunch with a team size <5 • High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.

We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).

Lucia | Director of Corp Dev · Product Marketing Associate · MLOps Engineer | Remote (NYC / SEA / global overlap) | $140K–$200K + meaningful equity

Distribution is one of the last durable moats left; models are commoditizing, but knowing how attention and demand actually move through a system still compounds. That's what we're building: a growth control plane that turns distribution into something you can model and act on with certainty. Get this right and the outcome isn't in question.

We're hiring across three roles:

Director, Corporate Development: own strategic partnerships, fundraising support, and M&A/inorganic growth. For someone who can operate at the intersection of deal-making and narrative, and help steer where this company goes next.

Product Marketing Associate: translate a technically deep product into sharp positioning and demand. For someone who can make causal modeling and world models land with real buyers. Experience with working with social media and influencers, Reddit strongly preferred. Data Science Background heavily preferred.

MLOps Engineer: own the infra behind our modeling; production pipelines and serving for causal graph inference, state space models, and world models (JEPA-I, JEPA-II style). Creating certainty in distribution, in production, not just in notebooks. Stack: Python, PyTorch, some Rust; GCP; Ray for distributed training.

Interview process: intro call, screen, virtual onsite, decision.

These kind of questions make no sense to me in an online application.

Does not belong on an online app if you ask me or in general. Still will see how it goes but not confident given the comments here.

Creating an account to apply is a bit weird

Supero | Cloud / Platform Engineer | REMOTE (SF Bay Area, CA, US · Bengaluru, KA, India) | Full-time | https://www.supero.dev/careers/cloud-platform-engineer/

We generate full-stack apps and deploy them — a generated app becomes a live URL, on our infrastructure or in the customer's own AWS or GCP account. It's in production and it has more shell script in it than it should. You'd own it, and the mandate is to make it boring. Kubernetes, GCP and AWS deploy paths, CI/CD, observability, cost, tenant boundary.

No on-call rotation today — it's the founders and whoever last touched it. Building a real one is part of the job, not something you inherit alone.

4+ years production infra, Kubernetes past the tutorial, AWS and/or GCP at depth. The rest is on the page, including the open problems that don't flatter us. I'm a co-founder — ask me anything here.

Biobase | Senior Technical Product Engineer, Technical Product Engineer (Early Career) | REMOTE (US, Canada) | Full-time | $150–230k / $90–170k + equity

Biobase has grand ambitions. We broker biospecimens, whole slide images, and the clinical metadata attached to them, on a supply-chain backbone that we're steadily automating. We’re building healthcare-data-focused agents on top of the datasets that we’re assembling, too.

We'd rather build the thing that removes the work than throw people at it. Two roles, one team, both reporting to the CPO:

Senior Technical Product Engineer ($150–230k + meaningful equity). The product team's technical interface. Architecture decisions and code review on the platform (Python/FastAPI, TypeScript/React, Postgres, Azure); the data pipeline and informatics that take specimen, slide, and clinical data in from suppliers and labs; and product ownership of the internal platform that builds our agents (permissions, evals, cost control, guardrails for sensitive data). You've been the reviewer of record somewhere, you've operated what you shipped, and you think in business problems before tickets.

Technical Product Engineer, early career ($90–170k + equity). Same territory at an earlier stage: the platform, the data pipeline and informatics, and the agents we run against our own operations — with a senior product engineer and our lead engineer reviewing your work and pairing when it helps. Open on background – self-taught, bootcamp, degree, research lab, a career you're leaving – selective on the bar. You've built something and someone else used it.

We build with Claude Code every day and expect you to become both fluent with it and skeptical of it. No ticket queue, no spec handed to you. Comp is salary + equity combos you choose between.

Full postings: https://biobase.ai/careers

To apply: email jobs@biobase.ai with something you built that eliminated manual work and what happened after it shipped. Links over resumes, no cover letter.

FlixTrain | Technical Expert Onboard Connectivity | Berlin, Germany | ONSITE (hybrid) | Full-time

FlixTrain is on a mission to make long-distance rail travel affordable and sustainable across Europe. Every passenger we shift to rail matters, and the onboard connectivity is a key part of what makes people switch.

We're hiring an Onboard Technology Manager to own everything that keeps passengers connected and crew productive on the train: Wi-Fi and network infrastructure, onboard units, and mobile devices for train staff. As satellite constellations and 5G redefine what's possible for high-speed mobile connectivity, you'll help set the direction for the technology being adopted on the largest non-governmental train fleet: writing specs, defining network architectures, monitoring live performance, and driving improvement projects from their conception to the finish line.

The role is highly cross-functional. You'll work with internal partners (operations, customer product, and rail engineering) and external ones, such as tech vendors (Icomera and Advantech) and train manufacturers (Siemens, Talgo).

What we're looking for:

- Bachelor's or Master's in Telecommunications, CS, Electrical Engineering, or similar

- 2+ years hands-on with network architecture, Wi-Fi systems, or Mobile Device Management (ideally in rail or a similarly complex environment)

- Strong troubleshooting skills on complex networked systems

Snowflake | Forward Deployed Engineer, Product Manager | Menlo Park, CA | Warsaw, Poland | London, UK | ONSITE

I’m part of Snowflake’s Applied AI / Forward Deployed Engineering team, and we’re hiring for multiple roles on the team.

We work directly with strategic customers to design, build, deploy, and improve production AI systems on Snowflake. That includes LLM applications, RAG and agentic workflows, evaluation frameworks, guardrails, observability, and production iteration using Snowpark, Cortex, and Snowflake’s native AI capabilities.

For the FDE role, we’re looking for strong engineers who can build and ship customer-facing AI systems end to end, especially if you’ve worked on LLM apps and care deeply about evals and quality. For the Senior role, we’re looking for someone who can lead multi-engineer AI engagements, mentor other engineers, and still be hands-on in architecture and implementation. The roles are customer-facing and involve travel, including at least 25% onsite time with strategic customers.

If you like working in ambiguity, building real AI systems instead of demos, and partnering closely with customers to get things into production, these roles are a good fit.

* Senior Forward Deployed Engineer, Menlo Park, CA: https://careers.snowflake.com/us/en/job/SNCOUSA253CD7A2E6945...

Trax | https://www.traxtech.com/ | Onsite Cebu PH, Remote Costa Rica, Remote US are possible | Full-time | Architect

I work best as a team - with someone who can challenge my assumptions and bolster my weaknesses. I'm looking to increase the bandwidth of the architecture function at Trax, as I can't do it alone!

We BOTH need to be strong in:

- Communication - we lead by influence, not by authority. Kindness is required!

- Ego-free problem solving - good ideas come from anywhere.

- Reliable software designs - things that work on dirty data, incomplete testing, and AI-enabled development workflows.

- Building the first prototype in an area with zero guidelines - careful choices and evaluation of vendors, setting an example to follow.

You should be strong in:

- Angular, Vue, Javascript, and web serving best practices for development organizations for long term health.

- Developer enablement and tooling in the Node.js ecosystem-shared component architectures, design systems, etc.

- Data-heavy applications and their operation and security needs.

I am strong on the infrastructure, DevOps, k8s, and backend and data stacks. So don't worry about relative weaknesses there, though you will need some understanding.

This would be a good first architecture position for a Staff or Senior Staff level full-stack technical leader who wants to expand their scope. My email is in my profile!

Confido Legal | Sr. Engineer | REMOTE (US only) | Full-time | $175k–$225k base

Confido Legal builds payments infrastructure for the legal industry. We're hiring a senior engineer to design, build, and maintain our software — leading architecture and product design, and translating business requirements into technical specs.

This is a broad, high-ownership role on a small team: you'll ship and maintain features end-to-end, lead architecture discussions, write clean and testable code, build automated E2E tests, do code reviews, and participate directly in company strategic planning. You'll also work closely with marketing and sales to keep technical work aligned with the business.

Greenzie builds the autonomy software that runs on commercial mowers. We don't sell the iron — Wright, Mean Green, Bobcat, and Greenworks Commercial do, with our stack on them. Mission is to free humans from repetitive outdoor labor. The software is on hundreds of machines in the field today.

We're hiring roboticists who want production robots doing real outdoor work, not lab demos. C++, Python, ROS/ROS2. You will own (or learn) a subsystem, debug messy field data, and ship to machines that mow for a living.

Mastra | Customer Engineer | REMOTE (AMER or EMEA time zones) | Full-time

Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed,https://github.com/mastra-ai/mastra

We're hiring a customer engineer. Some companies would call this an FDE; we don't, because roughly half the job is shipping in the framework itself. The other half you're embedded with paying customers deploying agents to production: in their Slack channels and on calls, writing code in their repos, reviewing their PRs, working through architecture with their engineers. What you learn there comes back as bug fixes, features, and new primitives in Mastra. One of our current customer engineers is among the top bug-fixers in the entire codebase.

You should be a full-stack TypeScript engineer who has built agents and who can explain technical decisions clearly to engineers who haven't seen your code.

Remote. We have a lot of EU customers and response-time SLAs, so US Eastern/Central or EU hours work best.

Process: a call with Shane (co-founder/CPO, leads customer engineering), a conversation with a customer engineer, a 2-3 hour take-home, then you present it to us and get feedback.

Apply: {https://jobs.ashbyhq.com/Mastra/05172cb0-47ec-44f9-9fe8-07d4...} We get back to everyone.

Springcraft | Manufacturing Engineer | On-site in Palo Alto, CA | Full time | $120k–$190k + equity

Springcraft is building the platform for physical AI.

Today, building robots and intelligent machines means navigating fragmented tools, incompatible hardware, and closed ecosystems. It takes too long, costs too much, and locks builders in. There is no default platform for physical AI. We're building it. Springcraft brings together purpose-built hardware, developer tools, and AI models into one open, integrated system so that builders can create machines that sense, understand, and act in the real world.

As the first manufacturing hire, you'll own how our hardware gets made, from first builds through volume production. This is a foundational, hands-on hire. You'll be on the bench and at the machines, partnering directly with our hardware engineers. You'll build the manufacturing function from zero and lead it as the company grows.

InfoHawk | Software Engineer | London, UK or NYC | REMOTE (UK or US), occasional onsite | Full-time | https://www.infohawk.com

Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...

You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.

We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep

I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:

- A server-authoritative game engine - seeds, nonces, outcome computation - A double-entry ledger where balance is derived and no client write can change it - Server-side enforcement of every limit and refusal - Payment rails idempotent under duplicated webhooks - Seed custody and the provably-fair lifecycle - An affiliate system with referral attribution and commission payouts

Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.

Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.

Astronomer | https://astronomer.io | NYC preferably, open to remote | Full-time

Hiring for ~10 eng roles listed at astronomer.io/careers, but the focus is specifically on distributed systems, observability, and applied AI.

Astronomer is a primary contributor to Apache Airflow and offers our customers a managed Airflow service with a similar business model as Databricks with Spark or Confluent with Kafka. Our tech stack is primarily Go, Python, and TypeScript. The problems we work on generally center around (1) building out our commercial managed Airflow offering, (2) building a data + infra observability stack on top of Airflow, and (3) building AI products and experiences that are genuinely load-bearing and additive to our customers experience on the platform.

We're also starting to write more about the work we're doing, this is pretty representative: https://www.astronomer.io/blog/astro-airflow-re-engineered-f...

Apply using our website or email me - my email is [firstname]@astronomer.io. Include HN in the subject to make sure I don't miss it! If you're emailing me, please include your resume, GitHub and a short note on what you deem to be the most interesting thing you've worked on.

Oooo, scandal company!

MIRA | Firmware Engineer | San Francisco, CA | ONSITE | Full-time

MIRA builds lightweight AI glasses that act as a second brain: they remember conversations, answer questions in under a second, translate 60+ languages, and surface useful context through a private display. We recently sold out and shipped our first batch, and have raised $6.4M from General Catalyst, Naval Ravikant, Pillar VC, and others.

We're hiring a firmware engineer to work close to the hardware across C/C++ or Rust, RTOS, BLE, embedded Linux, microcontrollers, sensors and audio pipelines, power optimization, device communication, and low-level debugging. We're looking for 3+ years of software or firmware engineering experience and a track record of shipping complex technical products end-to-end. Consumer hardware and early-stage startup experience are strong pluses.

This is a full-time, in-person role in San Francisco. We can't provide current or future U.S. visa sponsorship.

Senzing (entity resolution SDK) | Platform Engineer | Remote (USA) | Full-time

Senzing builds enterprise entity-resolution SDK technology — an embeddable library that runs entirely inside customer infrastructure with zero data exfiltration. We're hiring a platform engineer to own the AWS infrastructure behind Placekey (our location-data subsidiary), a production API service running at scale.

Day one, this is a cloud/platform role: you'd own the operational health of Placekey's stack, close out post-migration hardening, and have real input on where the infrastructure goes next. Over time the role grows to include internal IT and systems work (Active Directory, endpoint/laptop provisioning, Tailscale, security) — so we're looking for someone who's happy owning things end to end, not only the glamorous layer.

Stack: EKS Fargate, Aurora PostgreSQL, S3, Lambda, Cloudflare, API gateway (Kong/AWS), Terraform, Grafana/CloudWatch/Datadog. Apps are Scala and Rust.

Looking for: 5+ years platform/cloud infra, production Kubernetes (EKS ideal), managed Postgres (backup/recovery/tuning), IaC, solid networking, strong Python/Bash. You don't need to be an expert on the IT/systems side today — but you should want to grow into it.

Remote anywhere in the USA. Competitive salary, full health/dental/vision, 401(k) match, flexible PTO.

To apply: email enghiring@senzing.com with your resume and a short note — tell us about a challenging production system you've owned end to end, including an incident where your monitoring missed something and what you changed afterward.

Reframe Systems | Boston, MA | ONSITE or HYBRID | Full-time

We're creating housing on a mass scale through a network of robotic microfactories producing highly-customized buildings, from ADUs and cabins through townhomes and mid-rise apartments. We build with industrial efficiency while making buildings for an exact footprint, scale, style, and level of finish to fit any market, regardless of how tight the site or the zoning.

The core software problem is producing buildings designs without the typical months of design development and engineering. You can design natively in our building system or import existing designs, taking in a high-level architectural schematic and using that to generate a detailed manufacturable 3D model of the building (every stud, sheet of OSB, nail, electrical outlet, etc.) used to drive professional engineer review, permitting, and production. A compiler for a building.

Brilliant.org | Senior/Staff Software Engineer (Interactives) | Remote (North America), SF, NYC | Full-time | $180k-$250k | https://brilliant.org

Brilliant is building the world's first graphical AI tutor: a collection of interactive learning experiences that both the learner and their AI tutor can see and manipulate. In a world of cognitive offloading, Brilliant's AI gets people to actually think and solve hard problems.

We're hiring an interactive-focused engineer to craft the building blocks that power it. Each interactive exposes an API used by learning designers, our authoring agents, and the tutor itself. And every configuration those APIs can produce has to be a correct, solvable, meaningful puzzle. It's a tricky technical problem with a big payoff for our learners.

Engineers at Brilliant think about both "building the right thing" AND "building the thing right" while pursuing high standards of excellence for ourselves, our product, and our codebase.

Crossref | Head of Infrastructure Services | REMOTE | Full-time | 120k USD or local equivalent

I'm the Director of Technology at Crossref and I'm looking for a Head of Infrastructure Services to join my team. This role will lead the strategy and evolution of Crossref's infrastructure ecosystem, own the infrastructure roadmap, and lead and develop our Infrastructure Services Team.

Crossref is a not-for-profit organisation that runs infrastructure that connects thousands of scholarly publishers and millions of research outputs, serving an increasingly diverse set of communities across scholarly publishing, research, funding, and beyond. Our system is a complex mix of legacy and modern components, some parts over 20 years old and tightly coupled, running on AWS with Terraform, Java, Clojure, Elasticsearch, and PostgreSQL. You'll play a key role in our efforts to modernise this system into a set of more loosely connected services.

We're looking for someone who's as comfortable getting into the weeds of cloud infrastructure as they are leading a team. If you've grown from a strong technical background into leadership, and enjoy using your technical expertise to help a team do its best work, this could be a great fit for you.

This role is fully remote, we are hiring globally, but we will need at least 2 hours overlap with European timezones.

Full job description and application form here: https://www.crossref.org/jobs/2026-09-01-head-of-infrastruct... We don't use AI as part of the recruitment process, all applications are screened by me. For any questions, feel free to message me here: https://www.linkedin.com/in/dtkaczyk/

ODK | Senior Product Manager | Remote (Worldwide) | Long-term contract, 30–40 hours/week | $90–$110/hour USD

ODK is an open-source platform used by thousands of organizations worldwide to collect billions of data points for disease surveillance, supply chain traceability, environmental monitoring, and more. It enables users to build powerful forms and reliably collect structured data, even in places with little or no Internet connectivity.

ODK has been actively developed for 18 years. We have a mix of self-hosted and SaaS users across many sectors. We're looking for a senior product manager who will own product discovery and prioritization across this diverse user base.

Vitalize | Senior Product Manager or Staff Product Manager | San Francisco (hybrid)

What we do: Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.

Traction: - ~$37M raised - Launched 2024; ~$13M committed ARR across 10+ health systems - Live in 20+ hospitals and growing quickly

The role: We're hiring a PM to own the product experience that takes a hospital from signed contract to successfully using Vitalize in production. Getting there is complex: every health system has its own HRIS, scheduling workflows, union rules, and technical environment. This team builds the custom integrations and internal tooling that make those deployments faster, more repeatable, and less manual as we scale.

We're looking for a PM who... - Led messy third-party enterprise integrations deep enough to make real technical calls with eng - Has built internal tooling with an internal team as the customer - Prioritized a roadmap under live GTM pressure and held the line when the loudest deal wasn't the right build - Startup experience, where the system you were building didn't exist yet

Klassif.ai | ML/AI Engineer | Hybrid (Leuven, Belgium; remote 3 days/week)

We started off naively as just another intelligent document processing SaaS. Years of experience have shown us where the real pain points and value lies. Join my AI team and be horrified by how many critical business processes rely on email. Then help me execute on our ambitious roadmap!

If you find yourself nodding along with the following statements, you may be a good fit:

- You enjoy getting your work into the hands of users

- You’re okay debugging a stray tensor in the morning and designing services in the afternoon

- You care about the field of AI and interact with its community

- You can ‘sense’ when a loss curve is doomed

- You’ve fine-tuned LLMs, even just for fun

- You’ve been thinking a lot about agents lately, for some reason

- You don’t mind the odd bit of customer support (it’s where we get our best insights!)

All credentials welcome, including recent graduates. We’ll shape the role around you. What matters is creativity and visible engagement with the field.

Who may apply: EU citizens or holders of a Belgian work permit. (Everything else is more admin than we have time for.)

We are looking for adventurous builders to join us in two key roles to help bridge our platform and the hospital frontline:

Forward Deployed Engineer (£70k-£90k): You will be the critical link between our internal engineering team and hospital IT teams. While our SRE team focuses on core platform stability, you will own the site-specific implementations—navigating complex local networks, architecting integration paths, and ensuring our AI platform works across diverse environments. Stack: Linux, Kubernetes, JSON/YAML, Python, SQL, and healthcare interoperability standards (HL7v2, FHIR, DICOM). https://www.newtonstree.ai/job/forward-deploy-engineer

Site Reliability Engineer (£70k-£90k): You will ensure the reliability, scalability, and performance of our AI platform both in hospital sites (on-prem) and on the cloud. You'll work closely with customers to install hardware for Kubernetes clusters and collaborate with dev teams to ensure swift, reliable feature deployments. Stack: Linux, Kubernetes, Terraform, Ansible, GitOps (FluxCD), Argo Workflows, Talos Linux, Cilium CNI, Teleport, and monitoring tools (Prometheus, Grafana, Datadog). https://www.newtonstree.ai/job/site-reliability-engineer

Logistics: Both roles are Hybrid within the UK (with occasional in-person working in London and travel to hospital sites as needed). Please note that applicants must have the right to work in the UK, as we are unable to offer visa sponsorship.

To apply: Send your CV and a short note telling us why you'd be excited to work with Newton's Tree to info@newtonstree.com, or read more at the links above.

Odyssey | Sr. Security Engineer | Full-time | Remote (US) or NYC

Odyssey is building the leading financial technology platform for school choice. We help families access funding for tuition, tutors, curriculum, software, and enrichment programs—empowering them with greater educational opportunities.

We’re well-funded, backed by top investors including Andreessen Horowitz (a16z), and we are rapidly scaling.

As Odyssey's first Security Engineer, you'll have full ownership of our security posture — shaping strategy, building programs from the ground up, and driving best practices across our entire technology stack and product suite. This is a high-impact, high-visibility role where your decisions will directly influence how we protect our customers, vendors, and employees.

You'll partner closely with cross-functional teams to embed security into everything we build and ship, champion solutions to emerging security challenges, and ensure we stay ahead of an evolving threat landscape. You're someone who embraces AI tools to work smarter — whether that's accelerating threat detection, streamlining vulnerability analysis, or improving how we respond to incidents.

Pagelove | https://pagelove.com | Founding Software Engineer | REMOTE | Full-time | $110k–$130k + early equity

Pagelove collapses the modern web stack into its simplest form: no databases, no APIs, no application servers. Just HTML that works like an app, scales like a CDN, and is AI-native by design.

The page becomes the application, API and persisted state. Humans and machines can read and update the same surface directly using CSS selectors over HTTP, rather than through separate HTML and API/MCP interfaces. With Pagelove, AI can finally build web applications without having to deal with the complexity of the full stack.

We’re seed-stage and well-funded, hiring our first non-founder engineer. The codebase is Rust, with work including distributed storage, HTTP caching/ETags, CRDTs, parser/DOM performance, CI and production infrastructure.

Our development process is heavily agentic: Claude Code and Codex do substantial implementation work, with humans focused on architecture, review and the hard problems.

Harmonic | Technical Trainer | REMOTE (USA, East Coast based) | Full-time | 85k-105k USD

Key requirements: Up to 50% time can be mandatory travel for on-site in-person training sessions, very variable across the year. But no requirement to work in the office. Corollary to that - fluent or very good spoken English level is required. (PS: in actual practice it's about 1-2 work weeks every 2 months or so, irregularly)

Harmonic is a telecom hardware vendor. We are making hardware for the DOCSIS cable, PON fiber and mixed deployments.

Technical Trainer specialist is responsible for the presenting to the customer (MSOs) technical specialists, field technicians etc. the full overview of all possible product offerings by Harmonic, the full technical overview of every possible deployment (depending on the client's requirements) and full configuration for all hardware involved, including 3rd-party hardware. So no debugging and accessing code is needed, but if anything is customer facing, it must be explained.

As a brief example:

- Configuration for the DOCSIS core; - Configuration for the PON core; - Video streaming config; - Network L2/L3 switching configuration for multiple vendors;

The other half of the responsibilities is creating training materials, both text and graphics (designer is assisting our team too). Recording live narrated sessions too.

A familiarity with networking and/or DOCSIS is required. Both would be great.

Formal job listing: https://egmn.fa.us2.oraclecloud.com/hcmUI/CandidateExperienc...

Just apply at the link above, it's not a dead listing, we are actively looking for people now. Valid until I will comment otherwise. Reply under this comment for any clarifications.

Deya | Multiple Roles | New York, NY | HYBRID (NYC) or REMOTE | Full-time | https://deya.health/careers/

Everyone in health AI is chasing scribes and diagnostics. Almost no one is building the longitudinal data layer that captures what actually happens to patients over time. That is the real moat, and we are building it for eye care.

Deya sits between doctor and patient, capturing symptoms, treatments, outcomes and ocular images over time. Clinician-led, piloting with eye doctors, and we hold the largest dataset of eye images captured on smartphones. We build with AI tools daily.

Three roles, all high ownership:

Software Engineer (AI x Healthcare) - Product and infra from 0 to 1. Next.js, backend, cloud, agentic workflows, longitudinal clinical data.

Mobile Engineer (React Native, Swift, Kotlin) - A modern phone is already a clinical instrument and almost none of it has been pointed at eye care. Own the app and its UX end to end.

AI Engineer (Computer Vision + LLMs) - Own the vision pipeline turning phone photos into clinical signal, plus the LLM systems reasoning over patient history.

We have a proprietary clinical dataset and because we control capture, you can improve the data itself rather than model around its limits. Optometrists and ophthalmologists in-house to define ground truth and validate the work. Competitive salary plus equity.

All three roles and apply: https://deya.health/careers/

Cardog | Toronto, Canada or REMOTE | Full-time https://cardog.app/careers

We're the system of record for the Canadian vehicle: raw automotive data turned into facts that can be checked. Our open-source VIN decoder sits underneath a government vehicle registry.

Some of what's interesting:

- A government registry, a manufacturer's own filing, a listing site and an insurance record will describe the same truck four different ways, and nothing in any of those files says they're the same truck. Reconciling that, for every vehicle in the country, in a way that holds up when a regulator asks how you know, is most of the data work.

- Seventeen characters on a door frame encode manufacturer, plant, model year and build attributes — badly, inconsistently, and differently per manufacturer. Public reference data covers some of it. The rest gets worked out from filings, recall documents, and patterns inferred across millions of vehicles.

- We read vehicles directly over OBD-II now. Forty modules answered on a recent Hyundai, each reporting its own part number and installed software version. Nothing downstream of the VIN moves when a module is reflashed, so no registration, history report or dealer system knows what software is actually in a car.

Hiring: VIN Decode Engineer, Data Platform Engineer, Infrastructure Engineer, Founding Engineer (dealer platform). TypeScript, Postgres, Cloudflare Workers.

Checkly | https://www.checklyhq.com | Product Manager, Sales Engineer, Senior Sales Engineer | REMOTE (Europe / US Eastern) | Full-time

The best developers don't wait for a customer to tell them something's broken. They catch it first, in the pull request, in staging, or in the checkout flow at 3am, before a single user notices. That instinct is Checkly's whole reason to exist. We give developers and their agents the tools to own reliability the way they own their code: monitoring defined as code, powered by OpenTelemetry and Playwright, versioned and reviewed like everything else they ship. From pull request to post-mortem, in one place.

Open roles:

- Product Manager (DevTools & AI Reliability) - remote UTC-3 to UTC+3 - Senior Sales Engineer - remote Europe (UTC+1 to UTC+2) - Sales Engineer - remote US, Eastern time zone

Hiya | Senior Backend Software Engineer | Seattle, WA | HYBRID | Full-time | $113-197k + equity

Hiya's Voice Intelligence Platform protects 500M+ users from spam, fraud, and deepfake scam calls, and gives businesses branded, verified caller ID so the calls that matter get answered.

We're hiring a senior backend engineer for a small foundational team building our next-generation voice products from scratch: real-time SIP/RTP media handling, STT/TTS pipelines with tight latency budgets, deepfake detection and speaker verification, and conversational AI, all integrated directly into carrier networks. It's greenfield, so you'll be making the early architecture decisions, not maintaining legacy services.

Starlight | Senior Full-Stack Engineer | REMOTE (US), NYC preferred

I’m the Head of Engineering at Starlight, and we’re hiring a senior full-stack engineer.

We build software that helps financial institutions connect people with government benefits they’re eligible for. More than $100B in benefits go unclaimed every year because the underlying systems are fragmented and difficult to navigate. We’re trying to change that.

Our engineering team is intentionally small, so this is a high-ownership role. You’ll work across the stack, help shape our architecture and engineering culture, and have significant influence over how and what we build.

One area I’m especially excited about is building an “AI-first” engineering organization. I put that in quotes intentionally because I don’t think the industry has figured out exactly what it means yet—and neither have we. I want this person to help me figure it out.

I’ll encourage experimentation and use of AI, and we’ll have lots of conversations about what works and what doesn’t. But I’m not setting token quotas or mandating that people use AI for everything. I care much more about figuring out where it genuinely makes us better.

I’m actively involved in the hiring process and happy to answer questions about the team, role, or company.

Source (https://source.inc)| USA/Canada: REMOTE | Full-Time

Our mission: make handling memory, state, and context for AI agents outside the cloud as simple as it is in the cloud. Today it isn't close. An agent without data is inert, and outside the cloud, data is duct tape.

An agent in the field needs data that is verifiable, auditable, concurrent, collaborative, and permissioned. No single system gives you all five. SQLite gives you local storage and nothing else. Every other database assumes the cloud is there to provide the rest.

We're building the data layer agents actually run on: local-first, syncs peer to peer, every write verifiable, every read auditable, no cloud required. The stack is open source: https://github.com/sourcenetwork/defradb. We think it's the best memory an agent can have, bar none.

We’re growing fast and are looking to fill the following positions:

-Chief of Staff - https://source.network/careers/chief-of-staff

Akkio | Senior Software Engineers — FDE, Full-Stack, Backend | US (Fully Remote) | Full-time | $160k–$240k + equity | https://www.akkio.com/jobs

Akkio builds the AI platform the world's largest media agencies (Havas, Horizon Media, and others) use to run campaign workflows in production: audience building, media planning, measurement, and campaign analysis. Agentic workflows plus traditional ML, deployed on-premises inside agency cloud environments, directly on top of their data. We're ~50 people, past PMF, well funded, and growing revenue quickly.

We build agentically by default. Every engineer directs coding agents daily, and we're actively rebuilding our SDLC around that — not piloting it, not debating it. If you've felt that shift and want a team that's all the way in, that's us. We also run flat, so "senior" means ownership, not management layers.

Three roles, all $160k–$240k + equity:

* Forward-deployed engineer (FDE) — Python, TypeScript, true generalist. You embed with agencies whose systems steer billions in media spend and build whatever the problem needs: integrations, agent workflows, backend services. What you build in the field becomes product. Regular travel.

* Full-stack (web) — Vue.js, TypeScript, Node.js. You've run projects, guided architecture, and survived framework upgrades and large refactors. You care about the experience analysts live in every day.

* Backend — Python. Interesting work in at least two of: LLM systems and code generation, statistics, traditional AI/ML, large-scale data processing, distributed systems.

Details and application: https://www.akkio.com/jobs

All candidates must be authorized to work in the US.

Mondrio | Founding Product Engineer | San Francisco | ONSITE | $200k – $250k plus equity

Mondrio (https://mondrio.io) builds agentic pricing management: AI agents plus pricing experts that keep B2B pricing current rather than a one-off, one-time exercise. The founding team ran 150+ pricing engagements before starting the company and are translating that expertise to shape the next frontier of pricing in the agentic era.

The role comes with significant scope and high autonomy. You will own the full product lifecycle: customer discovery -> rapid prototyping -> agent-ready specs -> shipping via agentic orchestration -> o11y and evals -> growth & expansion.

Here are some domains you will ship: - Multi-agent simulation to emulate the behavior of a buying committee - A2A pricing interactions governed by OPA/Rego policies defined from natural language - Generative UX driven by a MCP server with full system capabilities access - Autonomous quote generation and real-time deal intelligence during sales calls

We don't have PMs or product designers so you serve as the product bridge between the founders, pricing experts, and engineering. If you're a mature engineer, looking to work with a very senior/staff team across the stack: customers, models, server, clients (web, TUI, chatbots), evals, then this is the role for you. In short, the role is ideal for someone who has significant product engineering expertise and has sharpened their SDLC competency to be AI-native.

Ohr | Data Engineer + Software Engineer | REMOTE (US) | $140K–$200K + Equity

Ohr is reinventing industrial chemistry from the atom up—turning breakthrough science into industrial alchemy.

We're hiring two engineers to help build the computational infrastructure behind it:

Data Engineer — Build the data foundation connecting laboratory instruments, scientific data, enterprise platforms, analytics, and AI systems.

Software Engineer — Build production AI tools, molecule-discovery applications, internal systems, and digital twins for processes scaling from lab to manufacturing.

We're looking for builders excited to learn the science and have their code touch the physical world. 4–8 years experience. U.S. person status required due to export-controlled systems.

Balerion AI | Software + FDE + AI Engineers | San Francisco, CA | ONSITE | Full-time | $250k+ base + seed equity | Visa sponsorship available | https://balerion.ai

We're building agentic AI for mortgage lending — automating document processing and income qualification for loan originators.

Underwriting a loan means pulling numbers out of a few hundred pages of paystubs, W-2s, bank statements, and tax returns, then applying underwriting guidelines that run to thousands of pages of edge cases. Most of it is still done by hand.

Problems we actually work on: routing scanned pages to OCR vs. text extraction when the text layer is unreliable; extraction pipelines where a wrong number is much worse than a missing one; running long agent workflows durably so a failure three steps in doesn't restart the whole loan; and evaluating multi-step output against guidelines that are themselves ambiguous. We put real effort into eval infrastructure, because "the demo looked good" does not survive contact with a lender's compliance team.

Stack: Python, PydanticAI, Restate for durable execution, Postgres, AWS. Frontier models from OpenAI and Anthropic plus open-source models where they win on cost or latency.

We raised an $8M seed led by Kleiner Perkins and have paying customers in production. Team previously at Snowflake, PayPal, Twitter, Atlassian, and Microsoft.

Comp: $250k+ base, meaningful seed-stage equity, 5% 401(k) match, full health coverage, commuter stipend, gym membership, daily office breakfast & lunch. Full relocation to SF covered.

Onsite in SF. Visa sponsorship: yes.

Xaira Therapeutics | Midlevel/Senior/Staff Engineers | Seattle or SF

Xaira Therapeutics is developing biological foundation models (not LLMs) to hit undruggable targets and cure disease. We've put together an incredible cross-disciplinary team of pharma veterans who have brought drugs to market, drug designers/AI scientists from Nobel laureate David Baker's lab, and engineers from tech in order to meet the moment and build a company to reimagine how drugs are made in the pursuit of better medicines. We're not a SaaS company, and the ultimate goal is to see the medicines we make delivered to patients.

I lead the engineering team and am hiring across multiple teams. There's:

- Research Engineering: work on a modeling team with the goal of making a model better. You think in tensors, understand what makes a kernel fast, and obsess over training throughput.

- X-Scientist: building an agentic copilot for drug development with access to our internal suite of tools. You have backend experience, have built tools for agents to interact with, and enjoy tinkering with agent harnesses.

- Data Engineering: we generate large volumes of data from our lab that provide critical feedback loops to our modeling efforts. You either hate or love lakehouses, have a preferred ETL orchestrator, and are intrigued by the problem of capturing data off of lab instruments.

- ML Platform: boy do we have some GPUs for you. Modeling teams need productive compute infrastructure, job scheduling, and numerous other affordances so that they can "just focus" on the model. You shudder at the words "falling off the bus", you have an opinion on how checkpoints should be recorded, and you've built tools that improve the modeling lifecycle.

Send me an email to apply: justin.yan@xaira.com Include a resume and tell me about something you've built that illustrates your skills.

Axo | Lead Founding Engineer | Sugar Land / Houston, TX (HYBRID) | Full-time | $120k–$160k + Founding Equity

Want to help out healthcare providers? Clinicians using our software are already saving hours a day and loving their job again. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.

Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector.
