- Design, build, and consume REST APIs on the backend

- Build scalable frontend interfaces with React

- Collaborate closely with the CTO and founding team to define technical direction

- Model and manage data using PostgreSQL and Supabase

WHAT WE'RE LOOKING FOR

Required:

- Proficiency in full-stack development with TypeScript/JavaScript and Python

- Backend experience with Node.js and REST API design/consumption

- Frontend experience with React for building scalable UIs

- Experience with PostgreSQL and Supabase for data modeling and storage

- Hands-on experience integrating AI/ML features via providers like OpenAI or Claude

- Ability to thrive in a founding-stage startup environment — owning features and shipping rapidly

- Strong communication and cross-functional collaboration skills
