Role Responsibilities

• Own the architecture, development, and high-quality release of mobile client features across UI, advanced navigation, state management, and offline behaviors.
• Lead the design and evolution of mobile client infrastructure, authoring comprehensive engineering design documents that align adjacent web, platform, and device teams.
• Trace and resolve complex, customer-facing bugs across service boundaries, including the GraphQL gateway, auth layers, and device control paths, contributing directly to backend repositories when required.
• Oversee the complete mobile release pipeline, managing EAS Build/Submit/Update toolchains, provisioning, TestFlight, staged rollouts, and rapid hotfix deployment strategies.
• Instrument applications for production stability—monitoring crashes, cold starts, and delivery metrics for WebSocket and push-driven real-time alert systems.
• Actively mentor junior and mid-level engineers, establish technical thought leadership, and elevate team-wide standards for code reviews, design docs, and testing paradigms.
• Partner directly with Product, Design, QA, and DevOps to translate complex business requirements into scalable, performant mobile technology.

Requirements

• 6+ years of professional software engineering experience, with a proven track record of shipping production mobile applications and driving cross-team technical alignment.
• 3+ years of professional React Native experience (or 4+ years of native iOS/Android with extensive production RN deployment) and an active portfolio in the App Store and Google Play.
• Deep production experience utilizing Expo (managed/bare workflows), EAS tools, TypeScript (strict mode, generics), and advanced client-state architectures (React Query, Zustand, Context).
• Strong background implementing production push notifications (APNs/FCM lifecycle), real-time network connectivity (WebSockets), and device-level authentication (OAuth/OIDC, secure storage, biometrics).
• Demonstrated success profiling real devices for startup speed, list virtualization (FlashList), memory leaks, and fluid animations (Reanimated).
• Proven ability to rapidly digest unfamiliar codebases, contribute meaningfully within a quarter, and effectively navigate legacy infrastructure lacking documentation.
• Exceptional interpersonal skills with the executive presence to guide cross-discipline design reviews and articulate complex technical tradeoffs clearly to engineering leadership.

Qualifications

• Nice to have: Native module development (Swift/Kotlin), WebRTC video streaming, offline synchronization patterns, automated mobile testing depth (Detox/Maestro), or familiarity with our broader stack (Node.js, NestJS, Apollo Federation, IoT).
