Fluids Analyst II, Combustion Devices
About The Position
At Relativity Space, the Propulsion team develops and delivers performant, manufacturable engines for the Terran R vehicle. The team owns hardware across its lifecycle, from initial design through production, qualification, and flight, and is exploring future engine modifications, including thrust upgrades, new cycles, and designs for mass production. The Fluids Analyst II will contribute to the design and qualification of combustion-device hardware—including injectors, thrust chambers, heat exchangers, and igniters—through computational fluid dynamics (CFD) analysis. The role reviews test and flight data to evaluate and anchor models, works with hardware designers to influence design decisions using thermofluid expertise, and develops and recommends analysis approaches that may reduce design iteration time. Accountability, collaboration, and execution are important to the role.
Requirements
- Bachelor's degree in a science or engineering field.
- At least 2 years of experience performing CFD analyses; employment, internships, and project experience count.
- Familiarity with typical analysis steps, including pre- and post-processing, meshing, and boundary conditions.
- Experience with basic engineering scripting in Python, MATLAB, or a similar language.
- Strong background in fluid mechanics and heat transfer.
- Commitment to accountability, collaboration, and execution.
Nice To Haves
