About the 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.

What You'll Do

  • 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.
