Overview
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.

Key Responsibilities Mechanical Design & Development  
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  Analysis & Validation  
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  RF-Aware Engineering  
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  Manufacturing & Delivery  
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)  Prototyping & Testing  
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  Requirements Essential  
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  Desirable  
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  Personal Attributes  
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  Additional Information Candidates must be eligible to obtain UK Government Security Clearance
