What You'll Do
Develop and launch the initial release of a mobile application focused on health optimization, using React Native with Expo and TypeScript. You'll take ownership of turning design concepts and product goals into a functional, reliable, and responsive user experience.
Design and implement seamless interactions between the app and both internal systems and external health platforms like HealthKit. Integrate AI-driven features, including LLMs and on-device processing, to deliver intelligent insights tailored to user behavior.
Work across the full development cycle—from defining API contracts to refining UI details—while ensuring code remains clean, testable, and performant. Help set engineering standards for testing, code reviews, and continuous integration as the mobile stack evolves.
Optimize for speed, security, and scalability, especially when handling sensitive health data. Your work will directly influence how users interact with their personal biomarkers and long-term wellness goals.
