Some random advice – job titles mean absolutely nothing in the industry at large. Your years of experience isn't changing. Your salary (presumably) isn't changing. Call yourself "architect" or "code monkey" or whatever else you want, absolutely no one will care.
That is what I am doing - calling myself a 'Senior Software Engineer' in my current job. As someone who has been a "Senior software engineer" in the past couple of jobs, it would definitely look odd to say that I am a "Software Engineer - 2" in my current job as that would look like a stepdown in level.
