Typical comp shape
Game engineers usually earn private rsu or options. Common employers include Epic Games, Riot Games, Roblox, Unity. Epic and Riot are private, so secondary tender offers become the main liquidity event for vested equity.
What California changes
In California, every RSU vest, NSO exercise, and ESPP purchase carries 13.3% state tax on top of federal. For a senior game engineer with $300k+ of equity income, the state layer routinely adds $25-45k to the annual bill.
State AMT for ISO holders
If your game engineer role grants ISOs (common at pre-IPO startups, uncommon at post-IPO mega-caps), be aware that California runs its own AMT calculation. An ISO exercise-and-hold here generates AMT at two layers, not one.
Planning cadence
For a game engineer in California, the three planning windows are: after each RSU vest (withholding check and sell-vs-hold), before any ISO exercise (AMT model at both federal and state), and in Q4 (estimated tax top-up to clear the safe harbor).
