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 Guidance, Navigation, and Control (GNC) and Performance teams are responsible for defining and analyzing how Terran R flies, from liftoff to landing.
