f7d8749a-72d6-407c-bf98-292ea630c73a Senior Propulsion Design Engineer responsible for designing and releasing propulsion hardware for the X-BAT UAV platform. Collaborates cross-functionally to develop manufacturable, testable, and flight-ready propulsion system components.

Responsibilities

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.
Own the design and release of propulsion hardware supporting the engine, fuel, oil, and bleed air systems.
Develop and maintain CAD models, drawings, and assemblies using Siemens NX with proper GD&T.
Translate propulsion architecture and requirements into hardware that is manufacturable, testable, and robust in flight.
Work directly with the machine shop, production, and technicians to support builds, resolve non-conformances, and drive iterative improvements.
Support test campaigns by providing hardware design support, instrumentation accommodation, and rapid iteration based on test findings.
Apply engineering judgment and analysis (e.g., hand calcs, ANSYS, FEA, GFSSP, REFPROP) to support sizing, load cases, and design validation.
Support configuration management, BOM control, and change processes using Teamcenter or equivalent PLM.
Participate in design reviews, interface control efforts, and root cause investigations related to propulsion hardware.

Qualification
