Notable employers in this market include Stripe, Airbnb, and Google, though the tech ecosystem sprawls across the Bay broadly. A median salary of $165,000 sounds solid until you factor in California's 9.3% state income tax and rents that run around $2,800 to $3,200 monthly for a one-bedroom in neighborhoods like the Mission or Hayes Valley.

Equity compensation often matters more than base pay in closing the gap between what you earn and what you actually take home.
