Role Summary

You will join a small, agile team as an external contributor for a 4-month term to build and deploy the MVP of a mobile application that integrates AI-driven, personalized wellness recommendations. Upon successful completion of the MVP, you may be considered for a full-time staff developer position, contributing long term to a fast-moving mission-driven product at the intersection of wellness and AI.

• Build and integrate CRUD functionality and an AI agent service layer using standard third-party APIs (e.g., Anthropic, OpenAI, Google).

• Ability to integrate mobile features using existing cross-platform plugins (camera, notifications, storage, GPS).
• No deep native iOS/Android development required.
• Familiarity with publishing apps to the App Store and Google Play, or willingness to learn the process quickly.
• Strong UI implementation skills and solid understanding of mobile-first product design.
• Comfortable working in a fast-paced, iterative startup environment with a high degree of autonomy.
• Experience with backend-as-a-service platforms (e.g., Convex, Supabase, Firebase).

Preferred Qualifications

• Exposure to LLM-based or agentic systems.
• Exposure to state-of-the-art agentic libraries (e.g., LangChain, Google SDK, Swarm).
• Prior experience shipping a 01 MVP for an early-stage startup.
• Interest in wellness technology and user-centered product thinking.

Compensation / Benefits

• Initial engagement as an external contributor on a 4-month contract to deliver and deploy the MVP.
• Upon successful completion of the contract, eligibility to be considered for a full-time role as a staff developer.
• If converted to full time, potential eligibility for benefits, equity, and other perks (details to be defined at that stage).

If you're excited to work at the intersection of wellness and AI and help build an impactful product from the ground up, we'd love to hear from you.
