**About Arrowfin**: We are looking for an experienced React Native Engineer to build the EdgeClear Mobile App from the ground up. ArrowFin is developing a web-based high-performance futures trading platform for EdgeClear, a futures trading brokerage. Your mission is to translate that desktop-grade power into a seamless, reliable, low-latency trading experience on iOS and Android.

**Key Responsibilities**:

- Architect and build the EdgeClear mobile app for iOS and Android using React Native and TypeScript.
- Implement real-time market data handling (WebSockets or equivalent) while keeping the UI responsive during high-volatility periods.
- Translate complex trading views (order books, DOM, charts, positions) into intuitive, touch-friendly mobile interfaces.
- Integrate with existing backend services and middleware for REST and streaming data.
- Manage native build configurations and support the App Store / Google Play release process.
- Collaborate with the web frontend team to share logic (types, hooks, utilities) and align patterns where appropriate.
- Design for mobile-specific constraints such as unreliable networks, reconnect logic, and safe input handling for trading actions.
- Implement secure authentication.

**Possible Stack**:

- **Core**: React Native (latest architecture preferred), TypeScript.
- **Styling**: NativeWind (Tailwind CSS for React Native) to match our web styling workflow, or standard StyleSheet if performance dictates.
- **State Management**: React Context / Redux / Zustand (aligned with web architecture).
- **Middleware Integration**: Consuming our existing Hono + Bun middleware for REST and WebSocket aggregation.

**Required Skills**:

- B2 or higher English language proficiency is required.
- 3+ years of professional experience with React Native and shipping high-quality iOS and Android apps
- Strong TypeScript skills; comfortable working with strict typing.
- Solid understanding of:

- React Native rendering behavior and performance optimization
- List rendering (FlatList/FlashList) for large or frequently updating data sets
- Navigation, deep linking, and app lifecycle events- Experience integrating REST APIs and ideally WebSocket-based real-time data.- Professional traits:

- High autonomy
- you may be the primary mobile engineer supported by a team of back-end and front-end developers.
- Attention to detail
- especially with critical trading inputs and error handling
- Strong problem-solving mindset, especially around mobile network and offline constraints

**Nice-to-Haves**:

- Experience building trading, fintech, or other real-time data apps.
- Hands-on work with WebSocket integrations in React Native.
- Experience implementing or integrating mobile charting (e.g., candlesticks, line charts).
- Familiarity with NativeWind or similar utility-first styling on mobile.
- Experience with monorepos or shared packages to reuse code between web and mobile.
- Exposure to native modules (Swift/Kotlin/Java) for performance-sensitive features.
- Experience setting up mobile app testing (unit tests, snapshot tests, or basic E2E flows).
