Mechanical Design Engineer 

Copello are currently supporting a leading technology business in the search for a Mechanical Design Engineer to join its engineering team, working on advanced RF, microwave and mmWave products across telecommunications, aerospace, defence and space.

This is a hands-on role covering the full product lifecycle, from concept and design through to prototyping, testing and production.

Key Responsibilities

• Design precision mechanical components and assemblies for RF, microwave and mmWave products, including enclosures, heatsinks, cooling systems and waveguide structures.
• Create detailed 3D CAD models and engineering drawings using SolidWorks.
• Develop lightweight, thermally efficient and structurally robust designs for demanding applications.
• Carry out or support FEA, thermal and CFD analysis to validate mechanical and cooling solutions.
• Work closely with RF, electronics and systems engineers to ensure mechanical design supports RF performance, EMI/EMC, thermal and environmental requirements.
• Apply GD&T, tolerance analysis, material selection and DFM/DFA principles.
• Design for manufacturing using processes such as CNC machining, die casting, additive manufacturing and sheet metal.
• Produce BOMs, manufacturing drawings and technical documentation.
• Support prototyping, environmental testing, first article builds and production introduction.
• Work with suppliers and manufacturing teams to resolve technical issues and improve designs.
• Support engineering changes, design reviews and continuous improvement throughout the product lifecycle.

Key Requirements

• Degree or equivalent qualification in Mechanical Engineering.
• Strong 2D/3D CAD experience, ideally SolidWorks.
• Experience designing high-precision mechanical components and assemblies.
• Strong knowledge of GD&T, engineering drawings, materials and manufacturing processes.
• Experience with CNC machining, particularly aluminium, would be advantageous.
• Understanding of thermal management, structural design and mechanical analysis.
• Experience working within multidisciplinary engineering teams.
• Familiarity with PDM/PLM and engineering change processes.

Desirable

• Experience within aerospace, defence, space or telecommunications.
• RF/mmWave experience, including waveguides, filters, amplifiers or RF assemblies.
• Experience with FEA, CFD or thermal simulation.
• Knowledge of MIL-STD, ECSS or other high-reliability design standards.
• Experience with environmental qualification, vibration or thermal vacuum testing.
• Experience supporting suppliers, first article inspection or NPI.
