Staff Thermal Analyst, Propulsion

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful 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:

• Responsible for the thermal analyses on Aeon-R engines to guide design decisions and ensure reliability and performance requirements are met
• Responsible for the analysis of 3D-printed engine components complex mechanical assemblies and/or the thermal integrity of the fully integrated engine assembly.
• Work hand-in-hand with mechanical designers manufacturing engineers and junior thermal analysts to arrive at optimal solutions for the engine and vehicle programs
• Develop and execute tests to support development and qualification including hands-on work like test article integration instrumentation setup and data processing
• Guide the advancement of the Propulsion departments thermal analysis discipline by development of best practices standards documents and the training and mentorship of others

About You:

• Bachelors degree in a science engineering technology or mathematics field
• 8 years of relevant engineering experience
• Experience with Finite Element Analysis
• Experience with computer aided design (CAD) software
• Able to work completely independently balancing multiple deliverables with competing priority and deadlines
• Experience with defining thermal and fluid instrumentation suites for tests

Nice to haves but not required:

• Experience with Finite Element Analysis using ANSYS products including ANSYS Workbench ANSYS Classic and ANSYS Parametric Design Language (APDL) and ANSYS Customization Toolkit (ACT)
• Experience with Siemens NX and Teamcenter
• Familiarity with industry best practices
• Familiarity with aerospace standards particularly SMC-S-016
• Experience with phase-change heat transfer (boiling and condensation)
• Experience with design of liquid propulsion components and systems
• Experience defining best practices for thermal analyses of varying scope and levels of technical complexity for products throughout the full development cycle
