Staff Vehicle Fluid Systems Engineer (Product)

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 Stage Fluids team designs and delivers the propellant pressurant pneumatics and other fluid systems that turn structures into functioning rockets. The team has full ownership across design production test and flight maintaining a holistic view of Terran R focused not on isolated parts but integrated functionality. Working on-site at the factory means youre never far from the hardware enabling rapid iteration and tight feedback loops across design and manufacturing. You wont just be handed requirements: youll be expected to ask the right questions collaborate with partners across the company and ultimately find the best solutions for Terran R.

About the Role:

As a Vehicle Fluids Product Responsible Engineer you will be responsible for the fluid system architecture and function for a given vehicle product line. You will apply deep expertise in system architecture complex systems operations and fluid thermodynamics applications to guide hardware design system analysis manufacturing validation and operations.

You Will:

• Own the integrated stage-level fluid architecture and schematics ensuring seamless functionality across all propellant pressurant and pneumatic subsystems
• Lead cross-functional interface definitions and negotiations with partner vehicle teams (Propulsion/Engine Structures GNC and Avionics) to ensure flawless system integration
• Assist with sizing and fluid 1D steady-state thermofluids analysis at both the system and component levels when necessary to
• Define development qualification and acceptance testing scopes to buy down technical risk prior to vehicle-level integrated testing
• Participate in concept of Operations (CONOPS) development and operation data review to take ultimate ownership of the successful operational philosophy and testing execution of the fluid systems at the integrated vehicle level

About You:

• Bachelors degree (Mechanical Engineering or relevant)
• 7 years of experience working with complex fluids systems
• Strong background in fluid system architecture operations and application of engineering fundamentals in system design thermodynamics fluid dynamics and heat transfer
• Proficient with one or more fluid or thermal modeling tools for internal compressible and incompressible fluid analysis
• Experience using programming languages such as Matlab Python or C for data analysis or modeling
• Direct experience designing or operating launch vehicle or spacecraft fluid or propulsion systems

Nice to haves but not required:

• Experience with certification of a vehicle fluid system for NSSL and/or range certification
