Integrations Developer building custom API and data transformation solutions for MaintainX’s industrial work execution platform. Partnering with consultants, clients, Engineering, and Product teams.
About the role
- Senior React Native Engineer building Pack.com’s iOS and Android gamified shopping apps. Delivering high-performance animations, resilient data flows, and dual-store releases.
Responsibilities
- Architect tactile, gesture-driven interactions such as mystery pack tears, loot-box carousel reveals, card flips, and real-time drop tickers using React Native Reanimated, Gesture Handler, and Skia.
- Optimize frame rates and native performance across iOS and Android devices, eliminating thread bottlenecks, dropped frames, sluggish view hierarchies, and memory leaks.
- Build resilient mobile query pipelines with GraphQL and TanStack Query, including optimistic cache updates, pagination, network dropout handling, and reconnection reconciliation during live unboxings.
- Manage end-to-end deployment workflows for Apple App Store and Google Play, including TestFlight, provisioning profiles, store review navigation, testing tracks, policy compliance, Expo (EAS), fastlane, Sentry, and OTA updates.
- Leverage React Native New Architecture features, including Fabric and TurboModules, and develop custom native modules or haptics where JavaScript bridges limit performance.
- Lead engineering of Pack.com’s iOS and Android mobile apps from development builds through app store distribution as a hands-on individual contributor.
Requirements
- Strong production experience building and maintaining cross-platform mobile apps in React Native and TypeScript, with direct involvement in apps shipped to both the Apple App Store and Google Play.
- Deep, hands-on production experience with React Native Reanimated (worklets, shared values) and Gesture Handler.
- Experience with Shopify React Native Skia or custom canvas shaders is a major advantage.
- Ability to profile real devices using Xcode Instruments, Android Studio Profiler, and React Native DevTools to diagnose UI/JS thread contention and excessive memory footprints.
- Hands-on mastery of GraphQL and TanStack Query (React Query) for managing client caching, race conditions, mutations, and offline/reconnection state handling on unstable mobile connections.
- Practical experience managing builds and submissions through both Apple App Store Connect and the Google Play Console, as well as configuring crash monitoring (Sentry) and over-the-air (OTA) updates.
- Focused individual contributor prepared to write production code, optimize performance, and ship releases in a tight engineering team without people management overhead.
Benefits
- Direct IC Ownership: Pure technical focus with full autonomy over code quality, implementation details, and tooling choices directly alongside technical leadership.
- High-Growth Ecosystem: The financial backing and operational stability of a proven 2024 parent operator paired with the impact of rolling out a brand-new native mobile app.
- 100% Remote: Flexible, asynchronous work environment centered on shipped features and smooth mobile experiences.
