Lead the design, development, and integration of propulsion systems for our advanced UAV platforms. Responsible for ensuring that engines, powertrains, and associated subsystems deliver safe, efficient, and reliable performance across all flight conditions. Support the end-to-end introduction of new designs into production and operations.

The role is pivotal to shaping the propulsion architecture and ensuring seamless integration between airframe, power, and control systems.

• 
  
• Lead the design and integration of propulsion systems, including engine installation, vibration isolation, cooling, exhaust, and power transmission.
  
• Develop and maintain propulsion system requirements and interface definitions with airframe, fuel, electrical, and control systems.
  
• Support the development of test plans and participate in ground and flight test activities to verify propulsion system performance.
  
• Collaborate closely with avionics, airframe, manufacturing, and flight test teams to ensure successful integration and validation.
  
• Maintain relevant technical, compliance, operational and production facing documentation (maintenance programme, inspection checklists, etc).
  
• Conduct or coordinate analytical assessments and simulations (structural, thermal, and vibration) to validate designs.
  
• Provide technical guidance and mentorship to junior engineers, contributing to the team’s growth and knowledge base.
  
• Other responsibilities as agreed with your manager.
  
• Act always in a safe manner and in support of our Health and safety agenda.
  
• Work in accordance with company values, policies, procedures and guidelines.

• Degree in Mechanical, Aerospace, or related Engineering discipline (or equivalent).
  
• 8+ years of experience in propulsion system or engine integration design, preferably within aerospace, UAV, or high-performance vehicle sectors.
  
• Strong understanding of mechanical design principles related to rotating and reciprocating machinery.
  
• Demonstrated ability to work across disciplines and manage complex integration challenges.
  
• Excellent communication, analytical, and problem-solving skills.
  
• Experience introducing and supporting new systems into production and into operations.
  
• Experience with air-cooled engines, hybrid propulsion, or alternative powertrains.
  
• Background in UAV power system certification or qualification testing (desirable).
  
• Proficiency with 3D CAD software (SolidWorks preferred) and familiarity with PDM systems.
  
• Experience with FEA and vibration analysis, or CFD/heat transfer simulation (desirable).
  
• Understanding of propulsion system control and monitoring interfaces (desirable).
  
• Right to work within the UK.
  
• Vetting and security clearance (as required by role, location or client).
  

• 
  
• Technically rigorous with a hands‑on, proactive approach.
  
• Strong collaboration skills across avionics, aircraft systems, manufacturing, flight test & operations teams.
  
• Attention to detail and commitment to safety and reliability.
  
• Ability to lead technical workstreams and deliver results under tight schedules.
  

The above is only an outline of the tasks, responsibilities and outcomes required of the role. You will carry out any other duties as may reasonably be required by the company. The job description may be reviewed on an ongoing basis in accordance with the changing needs of the organisation.

You should pursue a programme of continuous professional development in accordance with any relevant professional registration or statutory requirements, while maintaining appropriate awareness of service provider requirements.
