Job description

About the Team: 

The Propulsion team at Relativity 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. But designing engines with a quarter million pounds of thrust is just the beginning. 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.

About the role: 

  • Contribute to design and qualification of combustion devices hardware (injectors, thrust chamber, heat exchangers, igniters) through Computational Fluid Dynamics Analysis
  • Review test and flight data as necessary to evaluate and anchor models
  • Interface with hardware designers and utilize thermofluid expertise to influence design decisions
  • Develop and recommend analysis approaches that may decrease design iteration time
  • A strong commitment to accountability, collaboration, and execution

About you:  

  • 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

Nice to haves, but not required:  

  • We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required
  • Graduate degree in a science or engineering field 
  • Experience in Siemens STAR-CCM+
  • Working knowledge of rocket engine subsystems, such as combustion devices
