About this role

Mountain View, CA | AI Fund | Full-time

AI Fund is a venture studio founded by Dr. Andrew Ng in 2017. We build AI companies from the ground up with corporate partners, investors, and elite founders, backed by a fund from top-tier global corporations and VC firms. Our purpose is to build AI companies that move humanity forward.

A Principal Builder decides which bets are worth making. The core of the role is technical insight applied to business judgment: seeing how a deep tech idea can uniquely solve a market need, and bringing the intellectual heft that elite founders and corporate partners respect in a co-founder. You drive each idea forward until it's either falsified and ended, or handed to a newly formed company.
