Responsibilities
You will lead a team that is responsible for the design and analysis of integration hardware, as well as overall engine layout and packaging.
Close collaboration with stakeholders within Propulsion Engineering (Combustion Devices, Turbomachinery, and Components) and external to Propulsion Engineering (Stage, Test Stand, and Integration) is essential.
Designs and packaging trades will be informed by both fluid and structural analytical and computational models.
You will strategically leverage 3D printing, as well as traditional manufacturing methods, to dramatically reduce the cost, weight, and part count of Aeon-R.
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.
