Infrastructure Technician III

Job Description

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 Stennis team at Relativity Space is responsible for designing, building, and operating world-class test stands to support the Terran R stages, engines, and components.

Unique to this location, you will have the opportunity to get hands-on experience with the fully integrated engine and stage assemblies, push the hardware to the limits, and witness rocket engines firing up close and personal! This team was critical to the launch success of Terran 1 and recently made fire on both sides of our dual bay Aeon R engine test stand, among many other firsts!
