An MCAD & Tool Designer within the Manufacturing Engineering department plays a critical role in supporting the industrialisation of new products from early prototyping through to full serial production. This position is responsible for conceptualising, designing, and developing specialised moulds, tooling, holding fixtures, and assembly aids that enable efficient, safe, and repeatable production processes, including:

• Design and develop jigs, fixtures, moulds, gauges and assembly aids for aerospace component manufacture and assembly, from concept through release to production Required to support
• Analyse engineering drawings and 3D models to define tooling requirements, tolerances and inspection strategies; apply GD&T to achieve required accuracy.
• Produce detailed 3D CAD models and 2D drawings, including BOMs and specifications, ensuring compliance with internal and customer standards.
• Industrialisation of products for prototyping and serial production.
• Collaborate with design, manufacturing, quality and shop floor personnel to optimise tooling for safety, ergonomics, cost, and producibility.
• Support build trials, commissioning, troubleshooting and continuous improvement of existing tools; implement design changes and maintain configuration control.
• Prepare usage instructions, maintenance plans, and inspection criteria; provide training and technical support to production users as needed.

A successful applicant will be working closely with design, manufacturing engineering, supply chain, and production teams. The MCAD & Tool Designer ensures that all solutions meet technical requirements, quality standards, and operational needs throughout the product lifecycle.
