The local read
Why hiring a typescript developer in San Francisco is hard
SF founders compete with OpenAI, Anthropic, and every Series B sitting on $200M in dry powder. A senior engineer offer that actually wins here is $400K all-in, plus relocation, plus equity refreshers. At seed stage that's most of the round.
One named engineer with AI agents now does what a four-person team used to. Three-week timelines instead of three months. Flat-price quote in 24 hours after a discovery call. Pacific Time, overlap with your Sand Hill investors and your early customers in the same window. Code in your GitHub from commit one.
A senior typescript developer here is a ~$388K year-one outlay after benefits, payroll tax, and the 60–90 day search. We're a $6,000+ flat engagement that starts inside seven days.

The work, concretely
What we'd own day to day
The same scope you'd hand to a salaried typescript developer, owned end to end on a flat-price engagement. No coordination overhead, no junior-on-the-bench, no estimation theatre.
- Strict-mode TS with no implicit any, no @ts-ignore creep
- Schema-first runtime validation (Zod) wired to compile-time types
- Shared types between frontend and backend via tRPC or generated clients
- Domain types modeled with discriminated unions — illegal states unrepresentable
- CI checks that fail on type regressions, not just runtime errors
