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 Engine Manufacturing team is dedicated to delivering high-performance engines and advancing innovative manufacturing systems that continuously improve cost, quality, and lead time. You're not just executing on designs; you actively provide input that shapes new hardware iterations and regularly interface with engineers to make critical decisions for the Aeon R program. Having successfully developed and refined processes for our initial development engines, the team is now focused on producing flight engines at rate for Terran R's aggressive launch manifest.

About the Role

As a Turbomachinery Engineer, you will produce components and assemblies for the fuel and oxidizer turbopumps of the Aeon-R and Aeon-R Vac engines. As a Propulsion Manufacturing Engineer, you will own the manufacturing trades and then develop the processes for fabricating, testing, and delivering critical Aeon-R hardware and subassemblies.

You will serve as the main point-of-contact between the manufacturing and design teams as we optimize Aeon-R architecture and scale manufacturing operations. To be successful in this role, you should thrive in ambiguity and drive your own projects to completion. You must have the passion, tenacity and resolve to work through challenging issues unique to rocket turbopumps and additively manufactured hardware. We are looking for someone multifaceted, and capable of working at the interfaces of design, development, and analysis of turbomachinery. Ideally, you have come from a fast paced, aerospace environment, having completed difficult projects while collaborating effectively with multidisciplinary groups.

About You

• Degree in engineering or related technical field and 2+ years of relevant experience
• Experience with turbopump assembly procedures, including rotor balancing, interference fits, clearance checks, structural proofing, and leak checks
• Manufacturing Process Experience: Fluids Testing, Machining, Additive
• Knowledge of general assembly and test procedures, including tolerance stack-up analysis, structural proof testing, and pressurized leak checks
• Experience with Siemens NX or other CAD and analysis tools
• Experience with Tooling design, including conceptualization, modeling and drafting, and detailed analysis

Nice to haves but not required

• Experience working with additively manufactured engine hardware
• Experience with GD&T (ASME Y14.5) and industry specifications
• Experience in a startup or agile development environment
• Experience working in a flight development program

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more!

Hiring Range: $112,000-$143,000 USD
