Job description

About The Team

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 Stage Manufacturing team turns design into reality, owning the build of Terran R’s primary structures. This isn’t about turning the same bolt every day; it’s about building the systems to build the rocket. Engineers and technicians work side by side, with deep collaboration and real-time feedback, to shape how we build better and faster. With a manifest and a launch date, it’s up to the team to deliver on Terran R: solving challenges in real time, optimizing for scale, and constantly improving processes. As the vehicle evolves, so will the factory, with opportunities to apply automation, machine learning, and advanced technologies. What we build here sets the blueprint for the future of scaled launch.

This is a first-shift position with a standard schedule of Monday through Friday, 5:00 a.m. to 3:30 p.m. PT. The role is structured around a 50-hour workweek, including 10 guaranteed overtime hours each week.

About The Role

• Collaborate with engineering teams on building the 1st Terran R mechanism assemblies
• Follow precise work instructions to successfully complete build operations
• Assemble and test complex electro-mechanical assemblies using a variety of hand tools and test equipment
• Work closely with a team of technicians to successfully execute daily operations

About You

• 5+ years of aerospace mechanical experience or related field
• Demonstrated ability to work in fast paced environments with flight hardware
• Proficient in using calibrated tools such as torque wrenches and precision inspection equipment
• Experience in wiring, harnessing, avionic, and building and testing of electro-mechanical systems
• Proficiency of relevant aerospace industry standards and specifications, showcasing strong attention to detail and concern for product quality
• Experience troubleshooting electrical mechanical assemblies

Nice To Haves But Not Required

• Experience with electrical testing, high and low voltage
• Airframe and Powerplant license
