My managers and principal engineers on my team made it clear that NOT actively working to build promotion packet materials and engaging in self-marketing within the company placed me at a lower rank over time.
It was explicitly not good enough to do my job as described.
They used a system called stack ranking and (unofficially) they would put people lower on the ranks on PIPs and prepare to let them go even if they were fulfilling their responsibilities to the letter (but not above)
Maybe this wasn’t the case for staff level engineers, but it was for mid levels (which I was at the time)
It's weird to count literally doing your job as requested as "coasting."
