The Role
We are looking for a high-intensity full-stack engineer with React Native DNA.
You understand that mobile engineering is a game of constraints: memory, CPU, and bridge latency.
You hate jank, obsess over 60 FPS animations, and understand that frontend extends into how the API is structured for mobile consumption.
You are not just building screens; you are building the standards that ensure our mobile performance never degrades.

Key Responsibilities
• Lead the architecture of our React Native ecosystem: implement patterns for robust offline-first capabilities, complex state persistence, and real-time data synchronization
• Design and optimize Python (FastAPI/Django) backend services to ensure APIs are tailored for mobile efficiency with minimized payloads, efficient polling, and WebSocket integration
• Own the frame budget: identify and fix render bottlenecks, memory leaks, and excessive bridge traffic to ensure the app always feels native
• Act as the final line of defense in code reviews: establish strict linting, TypeScript patterns, and automated testing using Detox and Jest
• Architect seamless mobile interfaces for interacting with AI stock agents, ensuring complex data science looks simple and responds instantly on a 6-inch screen
• Oversee or implement Native Modules in Swift and Kotlin when the JavaScript bridge cannot meet our performance standards

Ideal Candidate Profile
• 5–10 years of professional engineering experience; you must have shipped and maintained at least one high-traffic, complex React Native app from 0 to 1 in the App Store or Play Store
• Expert in React Native, TypeScript, React Navigation, and Reanimated
• Solid experience with Python (FastAPI/Django), PostgreSQL, and caching strategies including Redis
• Deep understanding of the mobile release cycle: App Store Connect, Play Console, and Fastlane
• Degree in Computer Science from a top-tier university; GPA 3.7+ preferred
• A track record of shipping: you treat the company's product quality as a personal reflection of your craft
