Requirements

10+ years of software engineering experience with significant time in mobile; 5+ years building and shipping iOS apps in Swift; 3+ years with React Native at scale
Expert in Swift/SwiftUI (and/or UIKit), Xcode tooling, Instruments, and Apple platform fundamentals (background tasks, permissions, Keychain, App Store Connect, TestFlight)
Strong React Native fundamentals (bridge/native modules, performance profiling, Hermes, Metro/bundling, OTA, navigation)
Proven track record designing reusable component systems (design tokens, accessibility, theming, API ergonomics, documentation)
Hands-on experience using AI to accelerate coding (scaffold code/tests, refactors, docs) and productizing AI in-app (safe prompts, evaluation, guardrails)
Depth in mobile data flows (REST/gRPC, GraphQL, streaming), offline-first sync, error handling, and app state management
Quality mindset: unit/UI/e2e testing (XCTest, snapshot testing, Detox), monitoring, crash analytics, metrics/SLOs
Security and privacy literacy suitable for healthcare contexts (e.g., PII/PHI handling patterns, least-privilege, secure storage)
Clear technical communication: design docs, ADRs, tradeoff analysis, and stakeholder alignments

Responsibilities

Own the mobile architecture across iOS (Swift/SwiftUI/UIKit) and React Native—modularity, performance, security, and observability
Create and maintain reusable mobile component libraries (design-system alignment, theming, accessibility, localization, dark mode)
Ship AI-enabled features that surface insights visually (charts/plots/progressions) and responsibly—privacy-by-design, auditable outputs
Raise engineering standards: testing (unit/snapshot/e2e), CI/CD for mobile, OTA strategies, release automation, crash analytics, and telemetry
Mentor and unblock engineers; drive clear design docs, ADRs, and code reviews; partner deeply with Product, Design, Data Science/Medical, and Security
Lead cross-team initiatives (performance, reliability, offline/edge patterns, network/data sync, app startup time, bundle size reduction)
Champion AI-assisted workflows to boost delivery speed and quality (intentional prompts, verification practices, secure usage guidelines)
Collaborate with Data Science/Medical to integrate model outputs safely and clearly into the UI, including uncertainty and context visualization
