About The Position

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.

Requirements

• 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.

Nice To Haves

• 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.

Responsibilities

• 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.
