Early-Stage Startup Engineer

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

• 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.
