About The Position

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 the growing demand for launch capacity. This role is on the Propulsion team, which 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. 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. This role will contribute to the design and qualification of combustion devices hardware (injectors, thrust chamber, heat exchangers, igniters) through Computational Fluid Dynamics Analysis. The engineer will review test and flight data as necessary to evaluate and anchor models, interface with hardware designers, and utilize thermofluid expertise to influence design decisions. They will also develop and recommend analysis approaches that may increase design iteration time. A strong commitment to accountability, collaboration, and execution is expected.

Requirements

Bachelor's degree in a science or engineering field
2+ years of experience in performing computation fluid dynamics analyses (employment, internships, project experience)
Familiar with typical analysis steps including pre/post-processing, meshing, boundary conditions, etc.
Experience with basic engineering scripting in Python, MATLAB, or similar
Strong background in fluid mechanics and heat transfer
A strong commitment to accountability, collaboration, and execution

Nice To Haves

Graduate degree in a science or engineering field
Experience in Siemens STAR-CCM+
Working knowledge of rocket engine subsystems, such as combustion devices
Prior experience in aerospace is not required
