ONE Consulting have been engaged on a search assignment for a Mechanical Engineer, on behalf of a leading defence electronics business based in Gloucester. The role is on-site and well placed for mechanical engineers living in or commutable from Gloucester, Cheltenham, Tewkesbury, Cirencester, Worcester and the wider surrounding area. This is a hands-on Mechanical Engineer role working on the design, development and integration of bespoke enclosures, chassis and electro-mechanical hardware used in technically demanding, mission-critical applications. The work runs across the full project lifecycle: concept, design, build, test and delivery, so you see what you design through to a finished, working system. As a Mechanical Engineer here, you will be part of a capable, experienced multi-disciplined engineering group with strong technical depth across mechanical, electronics and systems design. The role: Designing mechanical hardware (enclosures, chassis and electro-mechanical assemblies) to meet challenging technical and environmental specifications. Producing 3D CAD models and detailed manufacturing drawings, and managing material selection and BOM. Building, testing, fault-finding and integrating prototypes through to environmental qualification. Working alongside electronics, embedded software and systems colleagues on multi-discipline projects. Producing accurate technical documentation and contributing to internal design reviews. Supporting project planning, technical risk reviews and continuous improvement. About you: You are likely to be a degree-qualified Mechanical Engineer or Mechanical Design Engineer (or close equivalent) with post-graduate industry experience, ideally gained in a technically demanding sector such as defence, aerospace, electronics, instrumentation or precision engineering. Useful experience and skills for this Mechanical Engineer role: 3D CAD design using SolidWorks, Creo, Inventor or similar, including detailed drawings and tolerancing (GD&T). Design of sheet-metal, machined and fabricated parts, with a good feel for design for manufacture. Enclosure and chassis design for harsh environments. Working from written requirements and producing clear technical documentation. Just as important for a Mechanical Engineer joining this team: a methodical, curious mindset, an interest in the underlying physics of what you are building, and a willingness to take a problem from rough idea through to a tested result. Due to the nature of the work, applicants will need to hold UK Security Clearance, or be in a position to obtain it. What is on offer: A varied Mechanical Engineer role with real engineering content. Direct access to senior engineers and the people making decisions. Long-term project visibility where you will see your work go from blank page to deployed hardware. A supportive, low-bureaucracy environment with a sensible approach to work-life balance. Competitive salary based on experience, plus a wider benefits package. To apply: If this Mechanical Engineer role sounds like the right next step, please apply with an up-to-date CV. Shortlisted candidates will be contacted to discuss the position in more detail.
