iOS Engineer

Location San Francisco Office Employment Type Full time Department Engineering Our Mission Build everyday AGI. Trustworthy, consumer-grade agents that redefine human–AI collaboration for millions. Software shouldn’t wait for commands; it should partner with you, amplifying what you can do every single day. You’ll own the iOS surface for our agent — the app, the keyboard, the share‑sheet integrations, the on‑device runtime, and every place an Apple user expects an AI agent to show up but mostly hasn’t. This is for the engineer who has strong opinions about ProMotion, who reads Apple Human Interface Guidelines for fun, and who can tell within thirty seconds of opening an app whether it was built by people who care. Tasks you will own The iOS app and SDK end-to-end — architecture, performance, and polish — alongside our CTO Our on-device agent runtime on Apple silicon, and the Apple framework integrations (Core ML, MLX, App Intents, Live Activities, Shortcuts) The boring-but-existential stuff — App Store review, entitlements, background execution, battery and thermal profiles Areas where you will assist Research, by helping land models that run fast and small enough on Apple silicon Product, by prototyping interaction patterns no one has shipped on iOS before Android engineers, by pushing back when something deserves to be deeply native vs. cross‑platform Skills you'll be expected to teach How to ship iOS that survives Apple review and feels first‑party How to read an iOS perf trace and find the actual bug Skills you'll be expected to learn Running LLMs on Apple Neural Engine at consumer scale What an agent looks like with full system context vs. inside the Apple sandbox Reliable agentic systems from the people who published the canonical papers on it Timeline of success After 30 days — You’ve shipped a meaningful improvement to our iOS app — perf, polish, or a new capability — that a user would notice. You’ve named three things below bar and started fixing one. After 60 days — You own the iOS roadmap with the CTO. You’ve shipped a capability that uses an iOS‑specific surface (App Intents, Live Activity, Shortcuts, or Apple Intelligence) in a way that makes the agent feel native. Other engineers ask you before they touch the iOS code. After 90 days — Our iOS experience is something you’d happily demo to an Apple engineer. You’ve shaped a launch and have a strong, opinionated plan for what an AGI iOS app looks like in twelve months that the team has bought into. Compensation Competitive cash and meaningful equity. Top‑tier relocation and immigration support. SF, in person. #J-18808-Ljbffr Pantera Capital
