Job description

Overview

• Build and launch the mobile app (iOS + Android) using React Native (Expo),
• Implement core features: daily health goals, meal logging
• Design and optimize a seamless, habit-forming user experience

The Role

We’re looking for an entrepreneurial Junior Full-Stack Developer who thrives on building from scratch. You’ll be the first dedicated engineer, owning the development of a mobile app that blends:

• Personalized nutrition
• AI-powered meal analysis
• Diagnostics-driven health guidance
• Habit tracking
• A frictionless experience for healthy living.

This is your chance to take full ownership, iterate fast, and lay the foundation for a product that could redefine how millions of people eat, live, and age.

What You’ll Do

• Build and launch the mobile app (iOS + Android) using React Native (Expo), owning development end-to-end.
• Implement core features: daily health goals, meal logging, AI-powered photo analysis, diagnostics integration, and personalized recommendations.
• Design and optimize a seamless, habit-forming user experience that makes healthy eating effortless.
• Develop and manage the backend (Supabase/Node.js), including user data models, authentication, and API integrations.
• Ship fast and iterate constantly, releasing frequent updates based on real user feedback.
• Establish technical foundations: CI/CD, analytics, secure data handling, and app store deployment.

What We’re Looking For

• Strong experience in React Native (Expo)
• Competent in full-stack development (Node.js / Supabase / TypeScript)
• Skilled in API integrations, auth flows, notifications, and mobile UI components
• Comfortable with rapid prototyping and building 0 → 1 products
• Hungry — wants to build something meaningful, not just follow tickets
• Entrepreneurial — thrives in ambiguity, moves fast, figures things out
• Obsessively user-centric — every detail matters
• Strong ownership and self-direction — you’ll be the first engineer
• Experience with AI/ML model integration.

Nice to Have

• Experience deploying apps on Apple App Store / Google Play
• Passion for health, fitness, longevity, or preventive care.

Fresh graduates with strong technical skills and a passion for building impactful products are welcome to apply.
