About the role

Key responsibilities & impact
  • As a Software Developer on iOS, you'll own the systems, architecture, and tooling behind apps used by millions.
  • Design, develop, and sustain high-performance iOS applications in Swift, SwiftUI, and Objective-C.
  • Lead architectural modernization — decompose monoliths, build shared libraries and frameworks, improve modularization.
  • Evaluate and adopt new Apple platform capabilities and lead their rollout.
  • Build and extend our internal AI harness — agents, automation frameworks, evaluation pipelines, guardrails.
  • Define observability standards, telemetry pipelines, and fault-tolerance strategies for production-grade mobile systems.
  • Partner closely with product, design, backend, and data; drive technical discussions.

Requirements

What you’ll need
  • Deep experience building production iOS applications with Swift and SwiftUI.
  • You've personally owned and operated a consumer iOS app at significant scale — 1M+ monthly active users or comparable.
  • Daily, fluent use of AI coding tools in real production work today.
  • Deep command of modern Swift concurrency (async/await, actors) and Objective-C interop within a large, long-lived codebase.
  • Technical leadership across multiple teams: you've owned the architecture of a major system or module.
  • Hands-on ownership of production reliability for mobile clients: SLOs/SLIs, instrumentation and telemetry pipelines.
  • A track record of measurable wins — performance, reliability, or user impact — that you drove.
