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 mission of the Engine Manufacturing department is to deliver high-performing products and innovative manufacturing systems while driving continuous improvements in cost, quality, and lead time. Through cross-functional collaboration, high levels of accountability, and a focus on safety we play a crucial role in building our reusable rocket, Terran-R. We are responsible for providing design feedback on new hardware iterations, pioneering and implementing advanced manufacturing methods and systems, and ultimately delivering engine and vehicle hardware for testing prior to launch. Over the past year, the Engine Manufacturing Team has successfully developed, iterated, and delivered processes and hardware for the first Aeon-R development engines. Now, we are entering a critical phase: producing flight engines that will pave the way for Terran-R's inaugural launch to orbit.
