Job Description:

We are seeking a Senior Propulsion Engineer to serve as the Responsible Engineer (RE) for a propulsion subsystem on the X-BAT platform, a next-generation UAV powered by a low-bypass turbofan engine. This role demands cradle-to-grave ownership of assigned propulsion hardware - from requirements and architecture through design, build, test, flight, performance validation, and operational support.

You will serve as the focal point for all technical matters related to your assigned subsystem-whether engine modules, fuel delivery, oil systems, bleed air, valves, or actuation - ensuring it delivers the required performance, integrates cleanly with the engine and vehicle, and supports the full range of operational demands. This role is hands-on, analysis-driven, and highly cross-functional-requiring collaboration with design, fluids, controls, airframe, manufacturing, flight test, and mission teams.

What you will do in this role:

• Act as the single-threaded owner for the engine, accountable for all technical decisions from concept to flight.
• Define and manage engine requirements, interfaces, integration strategy, and performance goals.
• Lead ground and flight testing of the engine, including instrumentation planning, data acquisition, and analysis of key performance parameters (thrust, fuel flow, margin, transients).
• Analyze engine performance data across the flight envelope to validate behavior, identify anomalies, and close design-to-mission gaps.
• Collaborate with airframe, controls, and mission engineering teams to ensure engine integration supports aircraft-level CONOPS, maneuverability, and reliability.
• Own engine-level fault management, failure investigations, and margin assessments.
• Guide the development of engine control logic and tuning, including throttle schedule design and transient response shaping.
• Represent the engine in design reviews, technical readiness checkpoints, leadership briefings, and customer engagements.

Required qualifications:

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline.
• 5+ years of experience in jet engine development, testing, and integration.
• Demonstrated ownership of engine hardware through test and flight operations.
• Strong knowledge of aerospace engine fundamentals, including thermodynamic cycles, thrust modeling, operability limits, and transient response.
• Hands-on experience in engine testing, including sensor planning, data systems, and test execution.
• Proficiency in Python for performance analysis, data reduction, and model correlation.
• U.S. Citizenship or ability to comply with ITAR requirements.

Preferred qualifications:

• Experience with low-bypass turbofan engines on UAVs, tactical aircraft, or similar aerospace platforms.
• Familiarity with GFSSP, REFPROP, ANSYS, or FEA to support performance modeling and test correlation.
• Experience with engine control development, feedback tuning, and transient validation.
• Background in rocket engine development with transferable test or turbomachinery experience.
• Proficiency with Siemens NX and Teamcenter for interface review and configuration context.
• M.S. in Aerospace Engineering or a related discipline.
