Senior/Lead Propulsion Engineer

The successful applicant will ensure that engines, powertrains, and associated subsystems deliver safe, efficient, and reliable performance across all flight conditions, supporting the end-to-end introduction of new designs into production and operations. This role is integral 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 documentation such as maintenance programmes and inspection checklists
• 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
• Act in accordance with Health and Safety guidelines and support the safety agenda
• Work in accordance with company values, policies, procedures, and guidelines

• Degree in Mechanical, Aerospace, or related Engineering discipline (or equivalent)
• 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
• Proven 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 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, and operations teams
• Attention to detail and commitment to safety and reliability
• Ability to lead technical workstreams and deliver results under tight schedules
