Senior Propulsion Analyst, Engine Systems Design & Analysis

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats 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 youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its 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 Rs 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:

• Bachelors degree in a science engineering technology or mathematics field
• 5 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
