The local read

Why hiring a mobile app 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 mobile app developer here is a ~$359K year-one outlay after benefits, payroll tax, and the 60–90 day search. We're a $10,000+ 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 mobile app developer, owned end to end on a flat-price engagement. No coordination overhead, no junior-on-the-bench, no estimation theatre.

  • Cross-platform RN with Expo prebuild for native modules when needed
  • Push notifications, deep links, OTA updates via Expo Updates
  • Store submission (Apple Developer + Play Console) handled end to end
  • Offline-first storage where it matters (TanStack Query persist or RxDB)
  • Crash reporting, analytics, performance instrumentation wired correctly

FAQ

About hiring vs engaging in San Francisco

How fast can you start?

+
Most engagements begin within seven days of the first call. There's no recruiter pipeline, no notice period, no relocation timeline.

React Native or native?

+
RN by default — 90% of features are identical and you ship to both stores at once. Native if you have hard requirements (live activities, complex camera, low-level audio).

Is this a full-time replacement?

+
No — we're a senior engineer on a flat-price engagement. For most pre-seed and seed-stage products, that ships more than a salaried hire would in the same window. When you outgrow it, we hand off cleanly to the team you hire.

Who owns the code?

+
You do, from commit one. Repo in your GitHub, infra in your cloud account. When you do hire someone, they onboard onto your code, not ours.
