About the Role

Join a fast-moving, pre-seed AI startup that is redefining how top talent finds their next opportunity — automating the headhunting process end-to-end with an agentic AI system. As a Founding Engineer Intern, you'll work shoulder-to-shoulder with the founding team, shipping production features daily and owning meaningful pieces of the product from ideation to deployment. This is a high-ownership, high-output role for a builder who thrives in lean, early-stage environments.

This is a hybrid role based in San Francisco, CA. Visa sponsorship is available.

What You'll Do

  • Build and ship end-to-end features to production on a daily cadence.

  • Collaborate closely with the CTO and founding team to own components from ideation through deployment.

  • Develop and iterate on a fully agentic system designed to automate headhunting end-to-end.

  • Engage directly with users to measure impact on hiring speed and candidate experience.

  • Contribute to a fast, high-output, low-ego engineering culture.

  • Work in a hybrid/hacker-house setup with a strong ownership mindset.

What We're Looking For

Dealbreakers (must-haves):

  • 6+ months of professional or project-based experience building production features in TypeScript and React.

  • Full-stack development focus with a demonstrated ability to build and ship end-to-end features — not primarily an ML engineer or heavily specialized in a single language (e.g., Python, C++).

  • Currently enrolled in or actively pursuing a degree in computer science, software engineering, or a related field.

Required:

  • Production experience with Supabase, Prisma, and Typesense in a React/TypeScript stack.

  • Experience using Cursor as a development tool.

  • Portfolio or GitHub showcasing full-stack projects and open-source contributions.

  • Standout credentials or projects — e.g., strong GPA, notable university, active GitHub, or recognized side projects.

  • Prior experience in entrepreneurial or early-stage environments with a rapid iteration and shipping cadence.

  • Strong ownership mindset — comfortable driving features from concept to production independently.

Nice to Have:

  • Openness to working in hacker-house settings, including locations in Latin America.

  • Comfort with a high-intensity, 7-day-a-week work pace during the internship.

Tech Stack

  • Languages/Frameworks: TypeScript, React

  • Tools & Infrastructure: Cursor, Supabase, Prisma, Typesense

Location & Logistics

  • Location: San Francisco, CA (hybrid)

  • Visa sponsorship: Available

  • Employment type: Internship
