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.

  • Fit up, fixture, tack, prep and clean parts. Inspect them with micrometers, calipers and torque wrenches
  • Program and touch up robot paths, align laser optics and maintain weld cells, KUKA or FANUC cobot experience is a plus
  • Run test welds with Weld Engineers to develop parameters, and troubleshoot equipment and weld defects
  • Record weld data in travelers, follow laser safety rules and Relativity Space standards, and help keep the team inclusive

Job requirements

  • 6+ years of hands-on laser or GTAW welding experience (manual, semi-automated or automated), preferably in aerospace to AWS D17.1 or similar requirements
  • Familiar with welding and fabrication of common aerospace alloys such as aluminum, stainless steel and nickel alloys
  • Can read blueprints and GD&T callouts, and can inspect parts and assemblies at every assembly level
  • Able to lift 25 lbs and work in confined spaces, reasonable accommodations will be made
