We're looking for a senior mobile engineer with real native iOS and Android depth to build the mobile experience for a secure healthcare app. The mobile app is the main product, and the standout features — Apple Wallet passes, home-screen widgets, Live Activity / Dynamic Island — are native OS extensions that can't be built in JavaScript. This is not a "React dev who also does some mobile"; it's a real mobile engineer. The app serves healthcare field representatives who need secure mobile workflows for managing documents, credentials, status visibility, and access in the field. What you'll own: - Web: React + TypeScript, working against an API client generated from the backend so the two never drift - Mobile (cross-platform): React Native + Expo for shared app UI and logic - Mobile (native): the real differentiators — Apple Wallet passes (PassKit), home-screen widgets (WidgetKit), Live Activity / Dynamic Island (ActivityKit) — native iOS (Swift) and Android (Kotlin) - On-device security: storing credentials safely with platform secure storage (Keychain/Secure Enclave on iOS, Keystore/StrongBox on Android) Must have: - React and TypeScript (modern hooks, a server-cache library like TanStack Query) - React Native and Expo, ideally on the current New Architecture - Real native iOS (Swift) and Android (Kotlin) experience, not just JS wrappers - App Store / TestFlight / Play Console release experience - On-device secure storage (Keychain/Keystore) awareness Strongly preferred: - Apple platform extensions: PassKit, WidgetKit, ActivityKit (Live Activity) - Working against a generated / contract-driven API client - Monorepo and shared-package experience - Front-end testing discipline

Core concept — it's a metronome built specifically for dancers. Instead of just a click or beep, it speaks counts aloud ("1, 2, 3, 4") or calls out dance-specific cues ("Slow, Slow, Quick, Quick") timed to the beat. Think of it as a rhythm coach rather than a musician's tool. The main features planned: Metronome with voice counts — numerical ("1, 2, 3…") or ballroom-style ("Slow"/"Quick"), where a Slow = half note and Quick = quarter note Move builder — users can sequence counts together to define a named dance move (e.g. "Foxtrot Basic: Slow, Slow, Quick, Quick"), tag it by dance style (Salsa, Waltz, Tango, etc.), and save it for reuse Umbrella sequences — group moves together into a full routine (e.g. "Rumba Basic Sequence" = Basic Square + Underarm + Crossover) Training modules — Step, Rhythm, and Freestyle modules with progressive learning, including biomechanical reminders ("Shoulders down", "Butt tucked in") and footwork diagrams Audio file player — upload a music file, adjust its speed, loop sections, and layer in voice callouts over it Goal tracking — log classes attended, moves learned, social dances, performances, etc. User accounts — login, subscriptions (monthly or annual), demographic profile (dance style, level, lead/follow), and progress memory across sessions Multi-device — phone, tablet, laptop, and TV casting In short: it's a dance training app that wraps a smart metronome with voice coaching, move choreography tools, and progress tracking — aimed at dancers from beginner to pro level across Latin, Smooth, and other styles.
