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.

• Design and develop jigs, fixtures, moulds, gauges, and assembly aids for aerospace component manufacture and assembly, from concept through release to production.
• 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.
• Industrialise 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.
• Develop detailed tooling concepts, layouts, and 3D CAD models (fixtures, jigs, moulds, dies, assembly aids).
• Present design concepts in reviews.
• Analyse data and write reports applicable to allocated tasks.
• Ensure that customer and project requirements are met.
• Geometric tolerancing to ensure designs meet manufacturability and serviceability requirements.
• Specify materials, surface treatments, heat treatments, and any other relevant processes where required.
• Produce specifications, BOMs, and engineering drawings for tool fabrication and procurement.
• Work with suppliers to source, quote, and qualify tool suppliers; manage tool fabrication, acceptance, commissioning.
• Collaborate with manufacturing engineers to integrate tooling within production lines; support prototype runs and process validation.
• Troubleshoot tooling issues (wear, alignment, repeatability) and propose corrective actions or improvements.
• Manage configuration and configuration management of fixtures, jigs, moulds, dies, assembly aids and tooling documentation and registers.
• Maintain a high level of confidentiality and integrity when handling company and customer data and documentation.
• Drive continuous improvement initiatives within your expertise and skillset.
• Investigate and introduce new tooling processes, methods, and technologies.
• Execute tasks within agreed to budgets and timescales.
