Mechanical Design Engineer Hartlepool 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 (SolidWorks) 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 waveguides, 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 (SolidWorks 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. SolidWorks Simulation/Flow) Knowledge of lightweighting 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
