Jobs in Stillington

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
