About The Role

You will lead a team that is responsible for the design and analysis of integration hardware, as well as overall engine layout and packaging. This role requires managing a small team, strong mentorship, project management, establishing priorities, communicating with leadership, providing technical guidance, and recruiting. Close collaboration with stakeholders within Propulsion Engineering and external teams 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. To be successful, you should thrive in ambiguity and know how to lead and guide projects to completion.
