Physical Superintelligence, Boston
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.
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.
We are seeking a Head of Core AI to lead Core AI: the team that builds the models, agents, and training systems that do physics. This is applied work in service of a product. Everything Core AI builds exists to make PSI's AI-for-physics capability better.
Motivation for this specific job is assessed at the first conversation: why this over a frontier lab.
Work Authorization: Candidates must be authorized to work in the United States. PSI is not able to sponsor or take over sponsorship of employment visas for this role, now or in the future.
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.
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 AI research judgment, technical depth, leadership track record, and shipping velocity. We are an equal opportunity employer and value diverse perspectives in building platforms for AI-driven discovery.
Export Controls. PSI's work involves technology that may be subject to U.S. export control laws. To comply with those laws, PSI may require that the person in this role be a U.S. person, meaning a U.S. citizen or national, a lawful permanent resident, or an individual granted refugee or asylum status in the United States, or be eligible to receive any required U.S. government export authorization. PSI will confirm eligibility with each candidate in the same way, and only to the extent export control laws require.
Equal Opportunity. PSI is an equal opportunity employer and does not discriminate on the basis of citizenship status, national origin, or any other characteristic protected by law.
