At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.
About the Team:
The Interplanetary Sciences Program is building a philanthropically funded Mars science orbiter targeted to launch in 2028. You will build the integrated hardware-in-the-loop (HITL) test capability that allows the spacecraft team to test early, continuously, and with real hardware. Then carry that ownership into final spacecraft integration and test leading up to flight.
This is a hands-on integration and test role spanning hardware, software automation, and spacecraft-level validation. You will take the HITL environment from an empty rack to a running, automated, always-on validation system that proves our payloads, avionics, flight software, and interfaces work together as intended.
You will build the bench, the software fixturing that exercises flight software against real and representative hardware, and the CI and regression infrastructure that continuously checks the system as it evolves. You won't just execute test procedures—you'll understand what each test proves, why it matters, and whether the result is actually credible.
You will work shoulder to shoulder with engineers across the spacecraft. If you like owning a capability end to end, debugging across hardware and software boundaries, and being the reason the rest of the program can move quickly with confidence, this is that seat.
