## Job description

## Overview

Physical Superintelligence is a startup with roots at Google, NVIDIA, Harvard, Meta, MIT, Oxford, Johns Hopkins, Cambridge, and the Perimeter Institute building AI systems to discover new physics at scale. We are seeking fundamental physicists, theorists and experimentalists, to run research campaigns on open problems with AI systems, and to make the results verifiable. Our mission is to discover and commercialize transformative physics breakthroughs at scale with artificial superintelligence, safely, verifiably, and for broad public benefit. The last century's golden age of physics gave us transistors, lasers, and nuclear energy. We believe artificial superintelligence will unlock the next one. We're creating the infrastructure to industrialize scientific discovery and usher in this new era. We have one product: new physics, at scale.

## Role and Responsibilities

- Run research programs on open problems in your area: formulate, direct AI systems at them, judge what comes back, own the result.
- Make physics legible to machines: encode what counts as a correct answer, verify AI output against it, and stand behind results before they leave the building.
- Go deep in one lane: quantum theory, many-body and condensed matter; statistical mechanics and complex systems; atomic, molecular and optical; high energy, particle and nuclear; gravity and cosmology; mathematical physics.
- Write the manuscripts and own the path to publication, working with AI researchers on how agents reason about physics.

## What We're Looking For

- Three or more years of research experience after a PhD, or five or more after a master's degree, with publications in top-tier journals in one area of fundamental physics, and rigor with a certificate behind it. You derive results and check them; you know when a numerical hint is not a proof and when a signal is an artifact of the setup; and you reach for exact or SDP certificates, interval arithmetic, computer algebra, proof assistants, or large-scale numerical experiments with the artifact ruled out, when the problem calls for them.
- Three or more years of hands-on work at the physics-ML intersection. You have used machine learning or AI systems on a physics problem, trained or directed a model, and can read a modern ML paper, reason about what an agent is doing, and say how to evaluate its output.
- Deep expertise in one area of theoretical or experimental physics:
- Quantum theory, many-body and condensed matter.
- Statistical mechanics and complex systems.
- Atomic, molecular and optical.
- High energy, particle and nuclear.
- Gravity and cosmology.
- Mathematical physics.

## Nice to Have

- Strong Python: production code, not just notebooks.
- Results on named open problems or conjectures in your field.
- Converting physics problems into machine-verifiable tasks; benchmark or verification systems for physics or mathematics results.
- Refereeing for top journals.

Related Roles If your background is computational or applied physics (CFD, FEA, multiphysics, surrogate modeling, digital twins), apply to Member of Technical Staff, Applied AI instead. That team does applied physics plus AI, and this role is fundamental physics.

## How We Work

We hold a high technical bar and give people full ownership of their work, from spec to ship to on-call. We write contracts before logic, test against real systems instead of mocks, and favor simple designs that ship over clever ones that do not. Our development process is AI-native: we work with agentic coding tools daily, write specs that are legible to humans and agents alike, and lead with leverage. Location and Compensation This role is hybrid, three days a week in person in our Cambridge, MA office. We offer competitive compensation including salary, benefits, and meaningful early-stage equity. We evaluate on physics depth, rigor, intellectual breadth, and shipping velocity. We are an equal opportunity employer and value diverse perspectives in attacking hard problems in science.
