Job description

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launchcapacity. But that’s just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science, exploration, and innovation, pioneering progress that reaches beyondthe 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. Nowis a unique moment in time where it’s early enough to leave your mark on the product, the process, andthe culture, but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Propulsion team at Relativity is responsible for the successful development of the engines that will power the Terran R vehicle. We own their design from concept through to launch and reuse. Our team partners heavily with Manufacturing, Test, Launch, and Integration teams, striving to develop our engines in record time and to support Terran R's first launch in 2026. As part of this team, you will help build, test, and iterate on the full product lifecycle of our Aeon-R engine systems, seeing them mature and eventually bring Terran R into space.

About the Role:

The Propulsion Integrated Design team owns the overall layout and packaging of Relativity’s engines, as well as the design and analysis of critical structural and fluids components. As a Responsible Engineer on the team, here are some things you may work on:

• Own overall engine layout and packaging, including conducting layout trade studies of different possible engine configurations
• Control and release the CAD/eBOM for top-level engine assemblies.
• Design and analyze hardware such as the engine gimbal, cryogenic and hot propellant ducting, fluid manifolds, tubing and secondary structures
• Lead the development of new methods for manufacturing or testing critical flight hardware to improve performance, reliability, and/or cost
• Collaborate closely with our partner teams: Manufacturing, Test and Vehicle Design

About You:

• Bachelor's degree in an engineering field and 5+ relevant industry experience
• Demonstrated project/technical leadership skills
• Strong understanding of engineering fundamentals in structures, fluids, thermal, and mechanisms
• Experience designing, assembling, and/or testing hardware

Nice to haves, but not required:

• Experience with Siemens NX and Teamcenter, specifically
• Experience in the design of liquid propulsion components and systems
• Experience with Finite Element Analysis (FEA) and commercial tools such as Ansys, Abaqus, or Nastran
• Familiarity with aerospace standards (AS, NAS, SAE, etc.)

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.
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!To see some of the benefits & perks we offer, please visit here.
