Propulsion Engineer

Propulsion Engineer - (Senior/Lead)
Salary: DOE
Full-time, permanent

We are working an organisation focuses on developing dependable, low-cost autonomous aircraft solutions designed to deliver long-range logistics and support where infrastructure is limited or unavailable. As a Propulsion Engineer you will be working on a self-flying cargo aircraft with integrated autopilot and mission control software, is in operation across various industries that require dependable, heavy-lift, long-range unmanned aerial systems (UAS). This role is based in Fareham.

Requirements of a Propulsion Engineer

Lead the design, development, and integration of propulsion systems for advanced UAV platforms. This role is responsible for ensuring that engines, powertrains, and associated subsystems deliver safe, efficient, and reliable performance across all flight conditions.

You will play a pivotal role in defining propulsion architectures and ensuring seamless integration between the airframe, power, and control systems, supporting the end-to-end introduction of new propulsion designs into production and operation.

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 creation and execution of test plans, and participate in ground and flight testing to verify propulsion system performance.

Collaborate with avionics, airframe, manufacturing, and flight test teams to ensure successful integration and validation.

Maintain relevant technical and operational documentation (maintenance programmes, inspection checklists, compliance records, etc.).

Conduct or coordinate analytical assessments and simulations (structural, thermal, vibration) to validate designs.

Provide technical leadership and mentorship to junior engineers, contributing to the team's capability and knowledge base.

Ensure safe working practices and uphold the organisation's health and safety standards.

Work in alignment with company values, policies, and procedures.

Qualifications, Skills & Experience for a Propulsion Engineer

Degree in Mechanical, Aerospace, or related Engineering discipline (or equivalent).
