The current place I'm at, and the last job I was at, do allow folks to hit the "senior/staff" and stay there. These are not FAANG and not early startups, but they're not exactly banks/utilities. These small-to-medium SaaS companies seem to find value in folks being effective in their roles for as long as those folks are willing to stay (duration, 3 years at each of these two employers, though I know folks who've been at each at their current level for 6+ years).
That kind of stability and valuing "being effective at the role your comfortable with" meant a lot to me. I also felt like I saw the best versions of each role and fewer folks stretching parts of themselves across different aspects of different roles.
