Dev salaries are pretty high? Are sales people really making what engineers make? I took a quick look at glassdoor for my company and it doesnt seem like it.
I personally know sales folks in large enterprises (say Cisco) who do a lot of travelling and are able to get base salaries of ~250k and commissions of ~400-500k a year, on top of essentially life time personal unlimited travelling due to millions of miles points accumulated. So yea, pretty high.
Salespeople in the tech space in SF start on about $70k (first year) and can expect to get to $200 (all in) after 5-7 years. Top reps aren't going find it hard to get $250k+ by their early 30s.
I don't know a huge amount about engineering salaries, but my guess is they're actually pretty similar across the board (although engineers start a lot higher).
I've done sales recruiting for about a year. I've only ever talked to one guy who's made more than $1m in a year. He was on a base of $125 or $150k. Last year he made $750k, and the year before that $1m.
But if you're a rep who's truly making $1m+ a year, you probably aren't planning on jumping ship anytime soon.
