Senior Robotics Software Engineer at Relivity Space Long , CA

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.

The Additive Technology team operates at the frontier of research and development, where creativity meets capability. This is an R&D‑driven environment where problems are open‑ended and solutions are yours to define. You’ll work alongside welders, robotics engineers, data scientists, and systems engineers at the intersection of hardware and software, creating an end‑to‑end additive manufacturing platform that serves a wide variety of applications.

From exploring new materials to unlocking faster print speeds, to designing complex, organic geometries that can’t be built any other way, it’s high‑impact work that sets the foundation for the future of additive manufacturing.

The Robotics Team at Relativity Space is responsible for building and refining the hardware that powers our autonomous systems. From advanced perception and robotics for manufacturing and additive processes to specialized robots that support development and deployment, our R&D Software engineers work in close collaboration with hardware and automation to develop cutting‑edge technologies that push the boundaries of space exploration and industrial manufacturing.

As a key member of the team, you’ll bring your software expertise to revolutionize the way robotics cooperate and additively manufacture here on earth and off planet.
