Propulsion Structural Engineer, Combustion Devices

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: 

• Support the design and qualification of Aeon-R combustion devices hardware throughout the entire development cycle, from initial concept through detailed design, testing, and flight, including high-fidelity modeling, test data analysis, model anchoring, and risk assessment
• Performing hand calculations and FEM analysis to achieve structural closure, including but not limited to static structural, thermal, fatigue, and damage tolerance analyses
• Interface with hardware designers to influence design decisions to ensure hardware meets performance and safety requirements
• Define test objectives that validate analytical models and verify hardware performance

About you:  

• Bachelor's degree in a science or engineering field
• 1 or more years relevant experience in structural analysis or structural modeling
• Experience applying engineering first principles in structural mechanics including but not limited to beam bending, pressure vessels, buckling, etc.
• Experience applying engineering first principles in thermodynamics, heat transfer, and fluid mechanics
• Familiarity with structural analysis packages (ANSYS, FEMAP, NASTRAN, ABAQUAS, etc.) 

Nice to haves, but not required:  

• Experience with ANSYS Mechanical -Graduate degree engineering or science
• Relevant experience in rocket engine development and/or test environment
• Working knowledge of engine subsystems, such as combustion devices
