Powertrain Engineer Internal Combustion Engine; ICE

The eVTOL Powertrain ICE Engineer will be responsible for the design, development, integration, and certification of internal combustion engine-based propulsion systems for a hybrid eVTOL Cargo UAV System. This role focuses on piston engine integration within a certified aircraft environment, ensuring compliance with applicable aviation regulations and system engineering processes.

• Lead the design and integration of internal combustion engine systems into hybrid eVTOL UAV architecture.
• Ensure proper integration of engine, fuel system, cooling, exhaust, and mechanical interfaces with the airframe and hybrid powertrain.
• Optimize engine performance for efficiency, reliability, weight, and operational envelope.
• Collaborate with multidisciplinary teams (aerodynamics, structures, avionics, flight controls).
• Apply system engineering principles in accordance with ARP
  4754.
• Develop system requirements, architectures, and verification/validation strategies.
• Support safety assessments in line with ARP
  4761, FHA, FTA, FMEA.
• Ensure compliance with applicable regulations such as CS UAS, SC VTOL, CS 23, CS E, CS P.
• Plan and execute testing programs to validate the performance and safety of the eVTOL powertrain.
• Analyze test data and iterate on designs to address any identified issues.
• Support certification activities, including documentation and authority interaction.
• Maintain verification documentation and compliance artifacts.

• Bachelor's or Master's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• Minimum 8+ years of relevant experience in aircraft propulsion or engine integration.
• Proven experience in certified aerospace projects and regulatory compliance.
• Strong knowledge of piston/internal combustion engines and fuel systems.
• Proficiency in simulation and modeling tools for powertrain analysis.
• Solid understanding of system engineering processes (ARP
  4754) and safety analysis (ARP
  4761).
• Hands‑on experience in testing, integration, and troubleshooting.
• Familiarity with hybrid propulsion systems is a strong plus.
