📋 Description

• Lead engineering of iOS and Android mobile apps from development builds through app store distribution. • Architect tactile, gesture-driven interactions such as mystery pack tears, loot-box carousel reveals, card flips, and real-time drop tickers using TypeScript, React Native Reanimated, Gesture Handler, and Skia. • Identify and eliminate thread bottlenecks, dropped frames, sluggish view hierarchies, and memory leaks across iOS and Android devices. • 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 Apple App Store and Google Play deployment workflows, 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. • Develop custom native modules or haptics where JavaScript bridges create performance limitations.

🎯 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. • Experience configuring crash monitoring with Sentry and over-the-air (OTA) updates. • Focused individual contributor comfortable writing production code, optimizing performance, and shipping 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.
