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.
What you'd do
- Design fluid systems (gas, liquid, cryogenic) including Piping & Instruction Diagrams (P&IDs), analysis, and component selection
- Design structural and mechanical systems including 3D modeling, analysis, and fabrication drawings
- Source components and develop detailed fabrication work instructions
- Bring new test stands to life by managing fabrication, activation, and initial operations
- Design and implement upgrades to operational test stands to enable new test capabilities
- Maintain test stands through preventive maintenance and rapid response to anomalies & equipment failures
- Conduct test operations on high-energy components, engines, and stages
- Control test stand and test article through GUIs and automation while monitoring cameras and telemetry
- Conduct flight acceptance, qualification, and development testing campaigns to validate designs and continuously improve the rocket
- Develop and optimize GUIs, procedures, control automation, and data review processes
What they want
- Proficiency in 3D modeling and drafting, including GD&T
- Strong engineering fundamentals in Thermal Fluid Systems and Structures
- Hands-on fabrication experience for complex assemblies
- Working knowledge of fluid components and ability to understand/develop fluid P&IDs for large-scale test systems
- Experience safely operating complex fluid systems, including high pressure gas, cryogenic fluids, flammables, and hydraulics
- Technical writing or documentation experience
About Relativity Space · Stennis Test
The Stennis Test team designs, builds, and operates test sites to evaluate Terran R's high-energy components, rocket engines, and both booster and upper stages. Team members are hands-on with these large-scale, complex systems, pushing hardware to the limits and directly contributing to flight readiness. The work is fast-paced, highly operational, and collaborative.
