Mechanical Design Engineer

Description This role is based at a state-of-the-art manufacturing and engineering facility in Sedgefield, County Durham. An exciting opportunity has arisen for a Mechanical Design Engineer to join an established engineering team, working on advanced RF and microwave products from concept through to volume production. The role offers the opportunity to work with experienced engineers, advanced design tools and in-house RF/mmWave manufacturing capability across telecommunications, aerospace, defence, space and other high-reliability applications. Purpose of Role To provide end-to-end mechanical engineering support for advanced RF systems, modules and amplifiers, ensuring mechanical performance, thermal efficiency, reliability, manufacturability, quality and cost requirements are achieved. Key Duties: Design precision mechanical components and assemblies, including lightweight enclosures, heatsinks, liquid cooling solutions and waveguide-based architectures. Develop modular mechanical designs considering mass, volume, mounting interfaces and serviceability. Ensure designs meet RF, thermal, mechanical and environmental requirements, including EMI shielding, structural stiffness, tolerance control, CTE compatibility, vibration, shock and ingress protection. Create detailed 2D drawings and 3D CAD models using SolidWorks. Select suitable materials, finishes and manufacturing processes to support performance, reliability and manufacturability. Carry out or support thermal analysis, CFD, conjugate heat transfer and FEA for vibration, shock, fatigue and other load conditions. Work closely with RF, electronics and systems engineers on features affecting RF performance, including cavity geometry, plating, tolerances, materials and precision alignment. Develop designs for manufacture, assembly and cost reduction using CNC machining, die-casting, additive manufacturing and sheet metal processes. Produce manufacturing documentation, including BOMs, GD
