• Create detailed 3D models, 2D drawings, and bills of materials
• Bring designs to life — from proof-of-concept through to prototype and final product
• Support the manufacturing process: material selection, finishes, tolerance control, and supplier liaison
• Tackle real-world engineering problems through hands-on build, assembly, and testing
• Maintain configuration control and detailed design documentation
• Mentor junior engineers and support collaboration across multi-disciplinary teams
• Drive continuous improvement in design standards, processes, and tools

What you bring

• Qualifications in Mechanical Engineering or a related field
• Experience in a similar mechanical engineering role, ideally within high-tech or defence sectors
