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.

This is a unique opportunity to be a part of an experienced technical team and build the skills necessary to create and refine robust component and engine building processes. This role will be focused on supporting several in-house processes and support resources such as precision cleaning, hydrostatic proof testing, flow testing, component assembly and test, and engine assembly.

  • Strong technical and interpersonal, written and verbal communication skills.

Nice to haves but not required:

  • Familiarity with 5S manufacturing principles.
  • Familiarity with Lean Manufacturing principles.
  • Experience transitioning from development into high-volume production

Benefits:

  • 100% health care coverage on your first day
