Physicist, Theo Collaborators Program

Remote, Worldwide

Overview: FirstPrinciples is an independent, non-profit research organization building Theo, the AI Physicist - an autonomous scientific system designed to reason about fundamental physics from first principles. Our long-term vision is to accelerate deep scientific discovery by combining machine reasoning with human scientific judgment.

As part of this effort, we are launching the Theo Collaborators Program: a small, selective group of expert physicists who will work with us to validate, guide, and stress-test the scientific reasoning produced by the AI Physicist in a focused research domain. This is not a tool evaluation program, and it is not a traditional advisory role. Collaborators engage with a concrete scientific direction, help assess whether the system’s reasoning is sound, and contribute to shaping what “good AI-generated physics” should look like.

The Theo Collaborators Program is open to late-stage PhD students, postdoctoral researchers, early-career faculty, and industry researchers with strong theoretical backgrounds.

We operate as a global nonprofit organization , with a Canadian foundation, a US-based 501(c)(3).
