Title bump + different salary band. There's other SV expats here with similar compensation packages. Base salary is lower, but it's made up for in loads of stock with very fast vesting schedules. Tax wise it's nice because I'm no longer paying California state tax or most of my federal taxes (via Foreign Earned Income Exclusion). I'm just sitting on loads of RSUs, I'll probably quit once I get my permanent residency and retire for a few years to sell off and rebalance my portfolio.
There's a good post that goes into how salary bands work in the EU for SV Expats [1]. Basically for global talent, the total comp can be 4x to 5x what a local dev would expect to make. For obvious reasons, this isn't widely broadcasted or talked about.
