The Role
We are looking for a High-Intensity Full Stack Engineer with a 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 APIis 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 theJavaScript bridge cannot meet our performance standards

• 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
