Senior Software Engineer, Flight Software; Rust

Position: Senior Software Engineer, Flight Software (Rust)
Umbra is an American space technology company delivering advanced systems, from sensors to spacecraft, that empower customers worldwide with unmatched access to critical information from space. Our mission is simple and ambitious: redefine space—for people, systems, and missions in every domain. Umbra’s ecosystem operates through three business units:
Remote Sensing (the data), Space Systems (the components), and Mission Solutions (the platforms). Together, our teams develop capabilities that deliver persistent access, resilient performance, and mission-ready solutions, advancing U.S. space leadership while keeping the world safe and informed.

About The Team

Space Systems – The Components Space Systems is where Umbra turns hardware and software designs into on-orbit realities; developing, implementing and iterating mission-ready core technology, while simultaneously advancing the next generation of our own satellite constellation. Space Systems is vertically integrated across the satellite architecture, thus the team designs, builds, and tests an array of critical components and subsystems, including power systems, communications, control systems, deployment hardware, avionics, and payloads, as well as the flight software, firmware and digital design solutions to support the entire hardware stack.

Our focus is on first principles engineering, and our mandate is simple: it has to work when it counts. Every bolt, board, and binary is proven on our own SAR constellation, ensuring flight‑proven reliability where failure is not an option.

If you want to work on cutting‑edge space technology that’s redefining what’s possible in space platforms, you belong here at Umbra.
