Senior Prototyping Engineer (f/m/d) – Aircraft Engine

As a Senior Prototyping Engineer – Hybrid Power & Fuel System Integration, you will become an integral part of our Prototyping team, supporting the development of our Reliant platform – a next-generation long-range eVTOL unmanned aerial system designed for demanding ISR and logistics missions. Reliant combines exceptional endurance, modularity, and operational flexibility to deliver mission-critical capabilities in the most challenging environments.

In this role, you will take ownership of the integration, development, and validation of the aircraft's hybrid power generation system, including the internal combustion engine, fuel storage and delivery system, generator, and associated electrical and control interfaces. You will ensure reliable, safe, and efficient operation of the complete propulsion system throughout the prototype development cycle by working closely with mechanical, electrical, propulsion, avionics, and systems engineering teams.

Lead the integration of the hybrid propulsion system, including the combustion engine, fuel system, generator, and power electronics into prototype aircraft.

Develop and validate fuel storage, distribution, and delivery systems, including tanks, pumps, filters, valves, sensors, and plumbing.

Design, build, and commission test rigs and dedicated test stands.

Develop and execute functional, endurance, and performance test campaigns for fuel and hybrid power systems.
