Job description

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 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 second-shift position with a standard schedule of Monday through Friday, 3:00 p.m. to 1:30 a.m. PT. The role is structured around a 50-hour workweek, including 10 guaranteed overtime hours each week. In addition to base pay, employees receive a 10% shift differential.

About the Role:

• Assisting in FSW operations which will include running the equipment, prepping welds for welding, and post weld blending
• Responsible for completing standard lift operations or assisting in critical lift operation
• Perform precision blending/deburring using a combination of standard power tools or hand tools
• Perform in process inspections using hand tools such as micrometers, calipers, and pi tape
• Uphold high Relativity Space standards regarding safety and shop cleanliness
• Foster and inclusive environment for all members of the team

About You:

• Experience with material joining processes (friction stir welding, arc welding, soldering, brazing, etc)
• Experience with metal fabrication techniques (forming, bending, etc)
• Proficient in the use of common hand tools and inspection tools
• Proficient in the use of Microsoft Office or other team communication tools such as Slack (or equivalent)

Nice to haves but not required:

• Experience with rigging and crane operations
• Experience with machining equipment (mill, lathe, etc)
• Experience with running CNC equipment or robotics
• Familiarity with NDT operations
