You want to exit big tech, but don't want to give up the comp? I think you may have to make a tough choice.
It's very possible that you'd be perfectly happy on less comp, in a role that's more fulfilling. IME, this is a fact that people realize 4ish years into a high-earning career.
For me, I realized that being happy every day is immeasurably more important to me than making a marginal pre-tax $150k/year, and that the FAANG environments are intentionally designed to be incompatible with what brings me happiness, day-to-day. YMMV.
