Senior Propulsion Test Engineer (R4639)

About the role

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.

You will serve as the focal point for propulsion testing, ensuring test results accurately characterize engine and subsystem performance, de-risk integration, and inform flight readiness decisions. This role is hands-on, data-driven, and highly cross-functional - requiring close collaboration with propulsion engineers, design engineers, technicians, controls, airframe, and flight test teams.

What you will do in this role

• 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.

Required qualifications

• Bachelor’s degree in Aerospace Engineering or a related engineering discipline.
• 5+ years of experience in propulsion or engine testing in aerospace development environments.
• Hands-on experience with engine test cells, test stand design, instrumentation, and DAQ systems.
• Strong understanding of gas turbine engine performance, transients, and test methodologies.
• Proficiency in Python (or similar) for data reduction, automation, and analysis workflows.
• Experience supporting flight test readiness and test-to-flight transitions.
• U.S. Citizenship or ability to comply with ITAR requirements.
• Ability to obtain a S//SAR level security clearance desired.

Preferred qualifications

• Experience testing low-bypass turbofan engines or propulsion subsystems on UAVs or tactical aircraft.
• Familiarity with REFPROP, GFSSP, ANSYS, or FEA to support test interpretation and correlation.
• Experience designing structural test fixtures, load paths, thermal management, and safety systems for hot-fire environments.
• Background in controls integration, actuator testing (e.g., TVC), and transient characterization.
• Experience operating in a test-driven, hardware-centric aerospace development environment.
• M.S. in Aerospace Engineering or a related discipline.
