Relativity Space is developing the Terran R rocket vehicle to deliver payloads to orbit. The Propulsion team is responsible for designing, developing, and qualifying highly performant and manufacturable engines. As a Fluids Analyst II, you will contribute to the design and qualification of combustion devices hardware—including injectors, thrust chambers, heat exchangers, and igniters—through computational fluid dynamics (CFD) analysis.
Key responsibilities include:
- Perform CFD analyses to support design and qualification of combustion device hardware
- Review test and flight data to evaluate and validate analytical models
- Interface with hardware designers and apply thermofluid expertise to influence design decisions
- Develop and recommend analysis approaches to reduce design iteration time
- Demonstrate strong commitment to accountability, collaboration, and execution
You will work within a propulsion team that emphasizes bottoms-up decision-making, ownership, and accountability at all levels. Engineers own the full lifecycle of their components, from initial design through production, qualification, and flight. The team is currently exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.
Requirements:
- Bachelor's degree in a science or engineering field
- 2+ years of experience performing computational fluid dynamics analyses (employment, internships, or project experience)
- Familiarity with typical CFD analysis steps including pre/post-processing, meshing, boundary conditions, and related workflows
- Experience with basic engineering scripting in Python, MATLAB, or similar languages
- Strong background in fluid mechanics and heat transfer
Nice to haves (not required):
- Graduate degree in a science or engineering field
- Experience with Siemens STAR-CCM+
- Working knowledge of rocket engine subsystems, such as combustion devices
- Prior aerospace experience is not required; varied perspectives and backgrounds strengthen the team
