About the role

  • 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.

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.
  • 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.
  • 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.

Requirements

  • You have shipped polished product surfaces that real users depend on, not internal tools or one-off prototypes.
  • You have an opinion on component architecture and can defend it against simpler-looking alternatives that do not scale.
  • When the role does not exist yet, you can carry the product weight yourself with taste the team trusts.
  • Comfort working across the stack into APIs, data layers, and platform integration.
  • You have built systems that handle real-time updates, streaming results, and partial failures gracefully.

Nice to have

  • Background in scientific computing, technical product surfaces (developer tools, data platforms, research interfaces), or other domains where the user is technical and the underlying capability is non-trivial.
  • Experience as the first or near-first product engineering hire at a fast-growing company, with a track record of standing up the function as the company scales.
  • This role is based in Boston.
  • We evaluate on technical breadth, product sense, shipping velocity, and the quality of what you have built.

Compensation

  • This role is based in Boston.
  • We will consider remote candidates on a case-by-case basis.
  • We offer competitive compensation including salary, benefits, and meaningful early-stage equity.
  • We evaluate on technical breadth, product sense, shipping velocity, and the quality of what you have built.

Company info

  • We are seeking engineers to build platform infrastructure at the intersection of computational science, AI systems, and software engineering.

Equal opportunity

  • We are an equal opportunity employer and value diverse perspectives in building platforms for AI-driven discovery.
