• 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.

About You

• Degree qualified in Mechanical Engineering, Aerospace Engineering or a related discipline.
• Proven experience as a Mechanical Engineer in aerospace, defence, automotive, motorsport 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, SolidWorks, 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.

Desirable Experience

• 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.

What You''ll Bring

• 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.
• A collaborative mindset focused on delivering high-quality results.

Why Join?

• Work on highly innovative aerospace and defence programmes.
• Be at the forefront of next-generation propulsion and aircraft technologies.
• Join a collaborative team of talented engineers and technical specialists.
• Hybrid working based around Marlborough.
• Excellent career development and progression opportunities.
• Opportunity to make a genuine impact on future aerospace capabilities.
