Wolviston Management Services is delighted to be working with our amazing client to recruit a Mechanical Design Engineer to join their established engineering team.

This is an excellent opportunity to contribute to the design and supporting programmes from initial concept through to full-scale production across telecoms, aerospace, defence and space sectors.

The Role As a Mechanical Design Engineer, you will provide end-to-end engineering support across, modules and amplifiers. The role demands a strong focus on mechanical integrity, thermal performance, reliability and manufacturability within high-specification environments.

You will play a key role in delivering robust, lightweight and thermally efficient designs suitable for demanding industrial and high-reliability applications.

• Design precision components and assemblies including enclosures, heatsinks, liquid-cooled systems and waveguide structures
• Develop modular architectures for integration into larger system-level assemblies
• Ensure compliance with RF, thermal, environmental and mechanical performance requirements
• Produce detailed 3D CAD models and engineering drawings (Solid Works)
• Define materials, finishes and manufacturing processes aligned to performance and cost targets

• Undertake thermal analysis including CFD to validate cooling strategies
• Perform structural and dynamic analysis (FEA) covering vibration, shock and fatigue
• Validate analytical models through testing and data correlation

• Collaborate with RF and electronics teams to optimise mechanical impact on RF performance
• Support design of wave guides, precision features and PCB-integrated assemblies
• Contribute to electromechanical concept development

• Design for manufacture, assembly and cost efficiency across CNC machining, casting, additive and sheet metal processes
• Produce engineering documentation including BOMs, GD&T drawings and assembly instructions
• Support prototype builds, first article inspection and production introduction
• Participate in design reviews and change control processes (ECN/ECO)

• Support build and validation of development hardware
• Assist with environmental and reliability testing (thermal, vibration, humidity, shock)
• Contribute to development of production tooling, jigs and fixtures

• Degree (or equivalent) in Mechanical Engineering
• Strong 2D/3D CAD capability (Solid Works preferred)
• Experience designing high-precision assemblies in demanding environments
• Knowledge of PCB integration, RF shielding and EMI/EMC considerations
• Good understanding of materials, manufacturing processes and GD&T
• Experience producing detailed engineering drawings
• Strong team collaboration and stakeholder engagement skills

• Experience in aerospace, defence, telecoms or space-related programmes
• Familiarity with RF/mmWave systems and high-frequency product design
• Experience with FEA and thermal simulation (e.g. Solid Works Simulation/Flow)
• Knowledge of light weighting and structural optimisation techniques
• Exposure to high-reliability standards (MIL-STD, ECSS)
• Experience with environmental testing and qualification processes
• Understanding of RoHS/WEEE compliance

• Strong analytical and problem-solving capability
• Detail-oriented with a proactive, hands-on approach
• Able to manage multiple priorities and deliver to deadlines
• Effective communicator across multidisciplinary teams and stakeholders
• Self-motivated and committed to continuous development
