Produce detailed 3D models, 2D manufacturing drawings, and BOMs using SolidWorks (or similar CAD software)
Own projects from concept through to completion, including DQ, FAT, and SAT support
Ensure designs comply with GMP, CE, and industry-specific safety standards
Work cross-functionally with Controls, Electrical, and Project Management teams
Perform risk assessments, DFMEA, tolerance stack-ups, and design reviews
Collaborate with suppliers and manufacturing to optimise for cost, performance, and ease of assembly
Mentor and coach junior mechanical designers and engineers
Continuously evaluate new technologies, materials, and design methodologies to improve machine performance and reliability
Plan the work using the approved Project Methodology and Standard Work-Flows and to the User Requirement Specification, through Design.
Own Design Reviews both internally and externally.
Check/Monitor detailed design drawings & bills of material completion.
Maintain live and accurate data in our PDM System.
Specification & sourcing of off-the-shelf components.
Liaising with manufacturers and OEM equipment providers.
Lead Design Reviews with the Automation and Electrical team so that the Machine Design foresees all of the requirements, including Mechanical, Automation, Electrical, Safety and Functional Performance.
Champion the Company Values in relation to GMP Design, Ease of Use and Maintenance, Repeatability, Efficiency.
Maintain the 'Sources of Truth of The Project in an Internal Design Specifications Folder so that Machine Building Team have an accurate source of reference and that Internal Pre-FAT and FAT Documents can be created.
