OVERVIEW
Physical Superintelligence is a stealth 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 engineers to build platform infrastructure at the intersection of computational science, AI systems, and software engineering.
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
- Own the customer-facing product surfaces at PSI end-to-end. Design and build the web applications, dashboards, and workflow interfaces that physicists, researchers, and engineering teams use to run physics discovery on our platform. Every screen ships with intent: clear information hierarchy, fast interactions, real-time feedback on long-running scientific workflows.
- Translate raw platform capability into product experience. Our AI agents run multi-hour physics simulations, search experiment spaces, and produce results that users need to monitor, compare, and act on. Build the interfaces that make agentic physics legible, not opaque, to a working scientist.
- Build for scale from day one. Component architecture, performance, accessibility, and observability are first-order concerns, not afterthoughts.
- Drive product decisions, not just implementation. You partner with other engineers, platform engineers, physicists, and product managers to decide what to ship and how it should feel. Strong product judgment is the differentiator; visual taste and engineering rigor are both table stakes.
WHAT WE'RE LOOKING FOR
- Five or more years building production user-facing products at companies known for engineering and product rigor. You have shipped polished product surfaces that real users depend on, not internal tools or one-off prototypes.
- Deep fluency with the modern frontend stack: TypeScript, React or comparable, the build and bundling layer, state management, and performance characteristics. You have an opinion on component architecture and can defend it against simpler-looking alternatives that do not scale.
- Strong product and design instincts. You can read a specification, identify what is missing, propose what should be there, and partner with designers and product peers when
the role
exists. When
the role
does not exist yet, you can carry the product weight yourself with taste the team trusts.
