f7d8749a-72d6-407c-bf98-292ea630c73a Senior Propulsion Test Engineer leads propulsion test campaigns for the X-BAT UAV, managing test architecture, execution, and data analysis. This role collaborates cross-functionally to ensure engine performance and flight readiness.

Responsibilities

We are seeking a Senior Propulsion Test Engineer to lead the planning and execution of propulsion test campaigns for the X-BAT platform. This role is responsible for end-to-end ownership of propulsion test activities—from test architecture and test stand design through execution, data analysis, and iteration - supporting a low-bypass turbofan-powered Group 5 UAV.
Own the propulsion test program from requirements through execution, data review, and test-to-flight handoff.
Architect, design, analyze, and build test stands and fixtures for engine, fuel, oil, bleed air, and TVC-related testing.
Define and implement instrumentation plans, DAQ architecture, calibration methods, and test procedures.
Lead ground test campaigns, including performance mapping, transient response, and edge-of-envelope testing.
Analyze test data to validate performance, identify anomalies, and drive design or control updates.
Partner with propulsion REs and controls engineers to ensure test coverage closes risk against CONOPS and mission profiles.
Drive root cause investigations for test anomalies and implement corrective actions.
Author test plans, reports, and readiness reviews; represent propulsion test in design and flight readiness reviews.
