Company Overview:

We invented a new approach to design, build, and fly our own rockets, starting with Terran 1 – the world’s first entirely 3D printed rocket and Terran R our reusable next generation 3D printed rocket.

Using our vertically integrated technology platform, leveraging additive manufacturing, artificial intelligence, and autonomous robotics to deliver superiority over traditional aerospace manufacturing methods, we’re disrupting 60 years of aerospace with our novelty approach to get to space, Mars, and beyond faster, more cost-effective, and more reliable.

We believe in a future where interplanetary life fundamentally expands the possibilities for human experience. Our long-term vision is to upgrade humanity’s industrial base on Earth and on Mars.


The Stennis team at Relativity Space is responsible for designing, building, and operating world-class test stands to support the Terran 1 and Terran R stages, engines, and propulsion components. As part of this team, you will help build and operate massive outdoor test stands at the historic Stennis Space Center on the Gulf Coast, the largest rocket engine test complex in the country. Unique to this location, you will have the opportunity to get hands-on the fully integrated engine and stage assemblies, push the hardware to the limits, and witness rocket engines firing up close and personal! This team is critical to the launch success of Terran 1, continued development of Terran R, among many other firsts! Check out this video to learn more about the Stennis test team.

What you’ll do:

Our mission is to change people’s conception of the way rockets are built and flown.

  • Plan, coordinate, and oversee any outsourced weld-related and certain material inspections
  • Review welded assemblies and provide input to engineers on the weldability and correct processes to use
  • Provide input on decisions of whether to accept or reject a given weldment
  • Document all quality assurance activities, consistent with company policies and procedures
  • Communicate significant issues or developments identified during quality assurance activities and provide recommended process improvements to management
  • Inspect, test, or measure materials, products, installations, or work for conformance to specifications
  • Measure dimensions of products to verify conformance to specifications, using measuring instruments such as rulers, calipers, gauges, or micrometers
  • Optionally: conduct other testing (example: soil, concrete, etc) and document results
  • Be aware of, and adhere to, safety practices and policies to ensure your own safety, as well as the safety of others who may be affected by your actions at work

What you need to know:

  • AWS Certified Welding Inspector (CWI) Certification
  • Minimum 5+ years of weld inspection experience
