Do you still ultimately do product engineering, picking tickets of a backlog, after 10 years at a FAANG if you’re not in management? Are the promotion levels mostly salary bumps? I spend some but far from most of my time writing code, I write RFCs, documentation, code reviews and emails, but don’t really know how this compares to positions at other companies. At some places a staff engineer seems to simply be a senior engineer who’s been around for a while.
