I'm in almost precisely the same position as you. Will be 9 years in December. I've been promoted three times and have the highest official position that an IC can have at this company. LCOL area, $150-175k / year depending on bonus, fully remote, devil I know, good FTO policy and work/life balance, etc. Even some equity (that seems to have a lower-and-lower expected value as the years pass, but that's another story)…
(Side note: I talked to a recruiter a few month ago who was telling me they lost clients left and right. Clients were mostly telling them they don’t have any issues finding talent on their own anymore)
