About the role

Senior Associate Builder at AI Fund focuses on rapid prototyping and market validation to determine real demand for new AI-enabled company ideas, working with partners, founders, and users to generate actionable market signals.

Responsibilities

  • Work with commercial partners, including corporates, VCs, and LPs, and with elite founders to identify, shape, and validate new company ideas.
  • Build prototypes that answer the open question about an idea. Start with the simplest design that works and add complexity only when the evidence calls for it.
  • Put prototypes in front of users, run user research, and turn what you hear into clear market signal.
  • Support partners and founders during the 12-week Build with hands-on product design and go-to-market work.
  • Present what you learned to the team and to potential founders: what worked, what failed, and what they need to decide next.
  • Stay at the frontier by reading papers, model cards, and technical writeups, and fold what you learn into the next build.

Qualifications

  • Technical ability, a real understanding of frontier AI, and hands-on experience coding with AI.
  • Experience as an engineer, product manager, or in go-to-market.
  • Hands-on experience building GenAI applications, such as LLM calls, RAG, agentic workflows, and evals.
  • Skill with AI coding tools like Claude Code, Cursor, or Codex, directing them to ship working software while you own the quality bar.
  • The judgment to write scrappy, disposable code for a fast prototype and clean code when it needs to last.
  • Personal experience and interest in building, hacking, and prototyping.
  • The ability to communicate with rigor and back your views with analysis.
  • A STEM or research degree from a top research university, or an equivalent background where you've built the same rigor.
