f7d8749a-72d6-407c-bf98-292ea630c73a Manager of Propulsion leading fuel system development and integration for the X-BAT vehicle with a fighter-class jet engine. Oversee architecture, integration, testing, and operational support of flight-critical fuel systems.

Responsibilities

We are seeking a Manager of Propulsion to lead fuel system development and integration for the X-BAT vehicle, powered by a fighter-class, afterburning jet engine. This role oversees the architecture, integration, testing, and operational support of flight-critical fuel systems operating across demanding thermal environments, aggressive maneuvering conditions, and mission-critical operating profiles.
Lead fuel system development activities from architecture through testing and flight operations.
Support and mentor fuel system REs responsible for fuel tanks, pumps, valves, vent systems, and associated propulsion hardware.
Drive system integration efforts considering elevated-G maneuvers, transient operation, vapor ingestion, cavitation, thermal effects, and fault tolerance.
Guide teams through fuel system thermodynamic and fluid dynamic trade studies involving heat soak, vapor pressure behavior, venting, and transient flow response.
Coordinate testing activities, instrumentation planning, and performance validation efforts.
Support failure investigations, root cause analysis, and design iteration activities.
Ensure schedules, technical execution, and supplier activities remain aligned with program goals.
Collaborate closely with propulsion, airframe, mission systems, and manufacturing teams.
