Descrizione del lavoro

Relativity Space is seeking a CFD-focused engineer to contribute to the design and qualification of propulsion hardware, including injectors, thrust chamber, heat exchangers, and igniters, using CFD methodologies. You will collaborate with hardware designers and apply thermofluid insights to guide design decisions and reduce iteration time.

We value a strong background in fluid mechanics and heat transfer, 5+ years of CFD experience, and scripting skills in Python or MATLAB.

Competenze

• 5+ years of experience performing CFD analyses.
• Familiar with 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.

Mansioni

• Contribute to design and qualification of combustion devices hardware through CFD analysis.
• Interface with hardware designers and use thermofluid expertise to influence design decisions.
• Develop and recommend analysis approaches to shorten design iteration time.
• Perform CFD reviews of injectors, thrust chamber, heat exchangers, igniters.
• Demonstrate accountability, collaboration, and execution in projects.

Descrizione del lavoro

At Relativity Space, we're building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that's just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we're writing together. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

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
