Responsibilities

You will lead a team of analysts that is responsible for the analysis of integrated design hardware, which consists of things like the Aeon R engine's gimbal, bellows, flex hoses, propellant ducts, manifolds, primary structure, secondary structure, tubing, etc.

Additionally, your team will own generating interface loads via engine assembly FEA models that drive the sizing of hardware across the entire engine.

You will also be a key voice in conversations pertaining to best practices for analysis approaches, acceptable design factors, material allowables, etc.

Close collaboration with stakeholders within Propulsion Engineering (Combustion Devices, Turbomachinery, and Components) and external to Propulsion Engineering (Materials, Design Criteria) is essential.

Responsible for the thermal, structural, dynamic, and durability (fatigue/fracture) analyses on Aeon-R engines and subsystems, 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 structural integrity of the fully integrated engine assembly

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.
