React Native Developer

About the Role

We are looking for a Senior Android Engineer with deep React Native expertise to build and own the trading

experience on Android — real-time data, interactive charting, fluid interactions, and rock-solid performance. What We’re Looking For

You have shipped production React Native apps that handle real-time data streams, complex UI states, and

performance-sensitive rendering. You understand the Android platform deeply — native modules, bridge

performance, and platform-specific behaviour. Ideally, you have worked on trading, fintech, or data-intensive

mobile products. You take ownership of your features end-to-end, care about code quality, and are comfortable

driving technical decisions independently. What You’ll Do

• Own the mobile trading experience on Android — architecture, performance, and end-to-end quality. • Build and optimize real-time data rendering — WebSocket lifecycle management, efficient list rendering, and minimal re-renders for streaming data. • Integrate complex WebView-based components with bidirectional JavaScript bridge communication. • Collaborate with product and design to deliver polished, intuitive interfaces for a financial product where

trust and clarity are paramount. • Define mobile engineering standards — component architecture, state management patterns, testing

strategy, and performance benchmarks. • Drive code reviews, mentor team members, and champion best practices across the mobile team. • Participate in stabilization and release cycles — profiling, device matrix testing, and regression analysis. Must-Have

• 4+ years React Native experience with production apps on Google Play Store. • Strong TypeScript skills and deep understanding of React Native internals — bridge, native modules, and

performance optimization. • Experience with real-time data handling — WebSockets, efficient UI updates for streaming data, and

state synchronization. • Experience integrating WebView-based components with JS bridge communication. • Proficiency with state management at scale (Redux, Zustand, or MobX).

• Experience with push notifications (FCM), deep linking, and complex navigation patterns. • Strong debugging skills — Flipper, React DevTools, native crash analysis, and performance profiling. Nice-to-Have

• Prior experience building trading, brokerage, or fintech mobile apps. • Experience with charting library integration in mobile apps. • Knowledge of server-driven UI (SDUI) patterns. • Experience with feature flags, A/B testing frameworks, and app modularization. • Familiarity with native Android development (Kotlin) for bridge modules.
