An excellent opportunity for an experienced Senior Mechanical Design Engineer to join a global RF technology group as part of a specialist R&D team in the UK. This role focuses on designing and developing advanced mechanical solutions for RF, antenna, and electronic systems used across aerospace, defence, naval, space and medical applications. The position is ideal for a highly motivated and innovative engineer with extensive experience in mechanical design for demanding environments, who thrives on solving complex technical challenges and working collaboratively with multidisciplinary teams across international sites.

Responsibilities

• Lead and contribute to the mechanical design of RF, antenna, and system products from concept through CAD, prototyping, fabrication and final assembly.
• Collaborate closely with RF and electronics engineers to optimise designs for challenging applications and integrate systems effectively.
• Produce detailed CAD models, drawings and analysis for strength, vibration, thermal behaviour, environmental performance and compliance with military standards (e.g. MIL-STD‑810).
• Support proposal generation with concept CAD, analysis and presales input.
• Develop and optimise prototypes, models, fixtures and specialised test equipment.
• Oversee environmental and mechanical testing, verification and product qualification.
• Work directly with suppliers and manufacturing partners to ensure high‑quality fabrication and testing.
• Industrialise designs and manage handover to production, including documentation, training and assembly instructions.
• Produce technical reports, customer‑facing documentation and participate in design reviews with customers.

Requirements

• Bachelor’s degree in Mechanical Engineering (Master’s preferred).
• Extensive experience in mechanical product design, ideally within defence, aerospace, naval or space applications.
• Proven ability to deliver designs from concept to CAD, fabrication and final assembly.
• Experience in design for environmental requirements including vibration, shock, humidity and ingress protection.
• Strong expertise in environmental qualification, product testing and verification.
• Mastery of CAD tools (e.g. Solidworks, Autodesk Inventor).
• Knowledge of composites, structures, aerospace, robotics or electromechanical systems.
• Practical experience in prototyping, machining and assembly.
• Experience working with suppliers, machinists and toolmakers.
• Proven track record of working directly with customers in a consultative and collaborative manner.
• Excellent problem‑solving skills, resilience and attention to detail.
• Shipborne, maritime or space‑related equipment experience.
• Thermal, ingress, corrosion and EMC considerations in enclosure design.
• Mechanical design of healthcare‑related products.
• Experience with FEA tools and MATLAB.
