Propulsion Design Engineer II, Valves

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:

In this role you will be responsible for the design analysis development and qualification of flow control devices for the Aeon R engine and Terran R launch vehicle.

Specific responsibilities will include:

• Design and analysis of clean sheet of cryogenic pneumatic proportional or solenoid valves
• Detailed fluid thermal and structural analysis of piece parts and assemblies
• Development and qualification test planning and execution of internally developed valves
• Engine and vehicle test support for existing flow control products
• Conducting trade studies to produce architectures and designs that satisfy system requirements

About You:

• Bachelors degree in relevant engineering discipline (Mechanical or related)
• 2 years of professional engineering experience
• Direct experience applying engineering fundamentals in thermodynamics structures fluid dynamics and heat transfer
• Experience with programming languages such as Matlab Python or C
• Experience with CFD and FEA tools (ANSYS)
