We are Foundational

We're an early-stage, mission-driven startup tackling one of the hardest and most exciting engineering challenges in the space domain: building the most precise understanding of space and Earth using ground-based lasers.

Using satellite laser ranging (SLR) and space debris laser ranging (SDLR) data, we're giving the next generation of space companies exquisite orbital data - the foundation for resilient navigation, Earth observation, and precise space traffic control. This is essential infrastructure for the sustainability and resilience of the space domain, and we think it will be foundational to the future economy.

Our network doesn't stop at the ground. To close the loop on precision, we're building the small optical payloads that fly on-orbit and talk back to our stations, and the systems engineering that ties ground, space, and data platform into one coherent whole. That's where you come in.

The role

This is a hands-on engineering role where the successful candidate will be as happy working in the lab as they are behind a computer. You'll work in our space team but may get involved in ground systems as well - helping to define what we build, model it, then get hands-on to build, test, and prove it.

You'll see the full lifecycle: early concept and trade studies, through modelling and design, into integration, environmental test, and validation against our ground network. It's physics-first, hands-on work with a quick path from your bench to orbit. You'll sit in a small team of software and hardware engineers who don't draw hard lines between disciplines, and you'll be expected to cross those lines too.

Specifically, you'll get stuck into:

• Systems engineering. Turning mission needs into requirements, interfaces, and budgets (mass, power, link, pointing, timing, error). Running trade studies and making the case for a design decision with number
