Senior Propulsion Test Engineer (R4640)

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.

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

Requirements

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

Nice to have

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; Ability to obtain a S//SAR level security clearance desired
