- Own end-to-end product areas from initial concept through deployment
- Design, build, and consume REST APIs on the backend
- Build scalable frontend interfaces with React
- Integrate AI/ML capabilities using providers such as OpenAI or Claude
- 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
- Willingness to work on-site in San Francisco (hackerhouse environment) or commute as needed
