Relativity Space is building rockets to serve today's needs and tomorrow's breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting growing demand for launch capacity. The company operates with a culture of autonomy, ownership, and impact at every level, where employees solve novel problems and see their work come to life rapidly.
The Stage Fluids team designs and delivers propellant, pressurant, pneumatics, and other fluid systems that enable Terran R to function. The team maintains full ownership across design, production, test, and flight operations, with a holistic view of integrated functionality rather than isolated components. Working on-site at the factory enables rapid iteration and tight feedback loops between design and manufacturing.
As the Stage Fluids Analysis Manager, you will lead a team of analysts providing essential technical guidance for hardware design and operations across fluid dynamics and thermal systems. You will apply deep expertise in internal flow and thermal analysis to guide component, systems, propulsion, and guidance/navigation/control teams.
Key responsibilities include:
- Manage a high-performing fluids analysis team aligned with program milestones
- Define, scope, and schedule required analyses to support program execution
- Ensure analysis fidelity is appropriate for each development phase
- Oversee resource planning and analysis progression to meet program timelines
- Set clear team goals and drive accountability
- Perform thermal-fluid calculations to size and design compressible and incompressible systems using hand calculations, custom scripts, network solvers, and CFD models
- Develop and execute CFD analyses for complex vehicle problems
- Collaborate across teams to ask the right questions and find optimal solutions
You will work on-site at the factory, never far from hardware, enabling rapid iteration and tight feedback loops. This is an opportunity to shape decisions and see your work come to life in record time, at a unique moment when the company is early enough to leave your mark on the product and culture, but far enough along that Terran R is tangible and gaining momentum.
