Careers

Come and build
with us.

We are a small, focused team working on genuinely hard problems. If you want your work to matter from day one, you are in the right place.

Why Supercritical

What it is like to work here.

Frontier science, real engineering

The core technology does not exist anywhere else. Every challenge is genuinely novel. You will not be maintaining a legacy codebase or refining a mature process.

Your work ships

Small team, short loops. What you design, build or analyse is in the lab or in the field within weeks. You see the results. You iterate on real data.

Backed and growing

Series A closed in 2025. Shell Ventures, Toyota Ventures, Al Mada Ventures and Lowercarbon Capital. The science is proven. The next chapter is commercial scale.

Two UK homes

The Global Technology Centre in West London, with lab, workshop and office space, and a second home in Teesside with an office and advanced scale testing facility. Not a hot-desk in a co-working space.
