Senior Propulsion Test Engineer (R4640)

Leads end-to-end propulsion test campaigns for low-bypass turbofan-powered UAV, including test stand design, instrumentation, execution, data analysis, and flight readiness. Requires 5+ years in engine testing, hands-on experience with test cells/DAQ, and Python proficiency.

About the job

Responsibilities

  • 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.

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.
