About the role

Performing hand calculations and FEM analysis to achieve structural closure, including but not limited to static structural, thermal, fatigue, and damage tolerance analyses

Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity.
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.
Interface with hardware designers to influence design decisions to ensure hardware meets performance and safety requirements

Bachelor's 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
Working knowledge of engine subsystems, such as combustion devices

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.
At Relativity Space, we are committed to transparency and fairness in our compensation practices.
We are an equal opportunity employer and value diversity at our company.
At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level.
