Job Description: We are seeking a Senior Propulsion Design Engineer to support the development and delivery of propulsion hardware for the X-BAT platform, a next-generation UAV powered by a low-bypass turbofan engine. This role spans the full lifecycle of propulsion system components - from early layout and design through production release, test support, and flight operations. You will be a key contributor to turning propulsion architecture into manufacturable, testable, and flight-ready hardware across the engine, fuel, oil, and bleed air systems. This role is hands-on, detail-oriented, and highly cross-functional - requiring close collaboration with propulsion REs, technicians, machinists, production, controls, airframe, and flight test teams.
