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.

Ship features to production on a daily cadence

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

Location & Work Arrangement

This role is based on-site in San Francisco, CA . The team works out of a shared hackerhouse/office environment. Visa sponsorship is available.
