About this role

ABOUT THE ROLE

Join a pre-seed AI startup as Engineer #4 on the founding team, working directly with the CTO and fellow founding engineers. This is a high-ownership, fast-paced role where you'll ship features to production daily and own entire product areas from concept to deployment. The company is building fully agentic systems that automate complex workflows — technically challenging, high-impact work at the earliest stage.

- 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
