Propulsion Structural Engineer, Combustion Devices

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 focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making free from technical gatekeeping where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification the team is now exploring modifications for future engines including thrust upgrades new cycles and design for mass production.

About the role:

• Support the design and qualification of Aeon-R combustion devices hardware throughout the entire development cycle from initial concept through detailed design testing and flight including high-fidelity modeling test data analysis model anchoring and risk assessment
• Performing hand calculations and FEM analysis to achieve structural closure including but not limited to static structural thermal fatigue and damage tolerance analyses
• Interface with hardware designers to influence design decisions to ensure hardware meets performance and safety requirements
• Define test objectives that validate analytical models and verify hardware performance

About you:

• Bachelors degree in a science or engineering field
• 1 or more years relevant experience in structural analysis or structural modeling
• Experience applying engineering first principles in structural mechanics including but not limited to beam bending pressure vessels buckling etc.
• Experience applying engineering first principles in thermodynamics heat transfer and fluid mechanics
• Familiarity with structural analysis packages (ANSYS FEMAP NASTRAN ABAQUAS etc.)

Nice to haves but not required:

• Experience with ANSYS Mechanical -Graduate degree engineering or science
• Relevant experience in rocket engine development and/or test environment
• Working knowledge of engine subsystems such as combustion devices
