Engine Systems Design & Analysis Team - Propulsion Analyst II

Long Beach, United States

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:

Responsible for the thermal, structural, dynamic, and durability (fatigue/fracture) analyses on Aeon-R engines to guide design decisions and ensure reliability and performance requirements are met
Responsible for the analysis of 3D-printed engine components, complex mechanical assemblies, and/or the structural integrity of the fully integrated engine assembly
Work hand-in-hand with mechanical designers and manufacturing engineers to arrive at optimal solutions for the engine and vehicle programs
Develop and execute tests to support development and qualification, including hands-on work like test article integration, instrumentation setup, and data processing

About You:

Bachelor's degree in a science, engineering, technology, or mathematics field
2+ years of relevant analysis experience, preferably with complex engineering systems
Experience with Finite Element Analysis
Experience with computer aided design (CAD) software
Detail-oriented, organized, and able to follow through
Strong drive to deliver on ambitious schedules

Nice to haves, but not required:

Experience with design of liquid propulsion components and systems
Experience with Siemens NX, Teamcenter, and ANSYS workbench
Familiarity with industry best practices
Familiarity with aerospace standards
