Mechanical Engineer - Advanced Aerospace & Defence Systems

Are you a skilled Mechanical Engineer with a passion for innovative design and complex engineering challenges?

We're seeking a talented Mechanical Engineer to join a growing engineering team developing cutting‑edge aerospace and defence technologies. This is an exciting opportunity for a design‑focused Mechanical Engineer to work on advanced propulsion and aircraft systems, contributing to projects at the forefront of aerospace innovation.

As a Mechanical Engineer, your primary focus will be the design and development of advanced mechanical and engine‑related systems. You'll play a key role in taking concepts from initial design through testing, validation and implementation, working alongside multidisciplinary engineering teams to deliver world‑class solutions.

This position would particularly suit a Mechanical Engineer who has experience designing engines, propulsion systems, or complex rotating machinery within sectors such as aerospace, motor sport, automotive, defence or other high‑performance engineering environments.

While direct aerospace experience is highly desirable, candidates from other engineering sectors with strong engine design expertise are encouraged to apply.

Working closely with Mechanical Engineering, Systems Engineering and Avionics teams, you'll help develop innovative technologies capable of operating in demanding real‑world environments.

• Lead the design and development of advanced mechanical and engine‑related systems.
• Create detailed designs and engineering solutions for aerospace and defence applications.
• Support engine development programmes from concept through to testing and validation.
• Develop testing plans, technical reports and engineering documentation.
• Perform structural, thermal and fluid dynamic analysis using simulation tools.
• Collaborate with Mechanical Engineering, Systems Engineering and Avionics teams to ensure successful product integration.
• Support manufacturing and assembly activities, ensuring quality and compliance requirements are met.
• Conduct root cause investigations and implement design improvements.
• Research and evaluate new materials, technologies and manufacturing methods.
• Ensure compliance with aerospace and defence engineering standards.

• Degree qualified in Mechanical Engineering, Aerospace Engineering or a related discipline.
• Proven experience as a Mechanical Engineer in aerospace, defence, automotive, motor sport or another high‑performance engineering environment.
• Strong mechanical design experience, ideally involving engines, propulsion systems or complex mechanical assemblies.
• Proficient with CAD and simulation software such as CATIA, Solid Works, ANSYS or similar.
• Strong understanding of mechanical systems, thermodynamics, materials and fluid dynamics.
• Ability to translate engineering requirements into practical, manufacturable designs.
• Excellent analytical and problem‑solving capabilities.
• Strong communication skills and experience working within multidisciplinary engineering teams.
• Right to work in the UK.
• Eligible to obtain and maintain UK Security Clearance.

• Aerospace propulsion systems.
• UAV or autonomous vehicle development.
• Additive manufacturing and advanced materials.
• Defence or military engineering programmes.
• Chartered Engineer status or progression towards chartership.
• Lean, Six Sigma or Agile methodologies.
• Full UK driving licence.

• A passion for engineering excellence.
• A hands‑on approach to solving complex technical challenges.
• Creativity and innovation in mechanical design.
• The ability to thrive in a fast‑paced engineering environment.
