- 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 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:
You will lead a team that is responsible for the design and analysis of integration hardware, as well as overall engine layout and packaging. This role will require managing a small team, requiring strong mentorship, project management, establishing priorities, communicating with leadership, providing technical guidance, and recruiting. Close collaboration with stakeholders within Propulsion Engineering (Combustion Devices, Turbomachinery, and Components) and external to Propulsion Engineering (Stage, Test Stand, and Integration) is essential. Designs and packaging trades will be informed by both fluid and structural analytical and computational models. You will strategically leverage 3D printing, as well as traditional manufacturing methods, to dramatically reduce the cost, weight, and part count of Aeon-R. To be successful in this role, you should be someone who thrives in ambiguity and knows how to lead (and guide) projects to completion.
About You:
- Bachelor’s degree in a science, engineering, technology, or mathematics field
- Experience with fluid systems design and/or structural design
- Experience in mentoring and demonstrated leadership skills
- Experience with computer aided design software
- Experience with Finite Element Analysis (FEA) and commercial tools such as Ansys, Abaqus, or Nastran
- Experience applying fluid, thermal, structural, and mechanical design fundamentals
- Experience driving to deliver on ambitious schedules
Nice to haves but not required:
- Experience in leading teams
- Experience in the design of liquid propulsion components and systems
- Experience with Siemens NX and Teamcenter, specifically
- Experience with large CAD model management, change management, and configuration management
- Familiarity with aerospace standards (AS, NAS, SAE, etc.)
