Technical Delivery

• Lead the design and development of mechanical systems, components, and assemblies.
• Produce and review engineering drawings, calculations, specifications, and technical reports.
• Develop robust engineering solutions from concept through to manufacture and implementation.
• Apply engineering analysis techniques, including FEA, to support design decisions.
• Ensure compliance with relevant engineering standards, regulations, and company procedures.
• Support design reviews, technical reviews, and engineering assurance activities.

Project Support

• Deliver engineering work packages to agreed quality, cost, and schedule requirements.
• Manage technical risks and support resolution of engineering issues.
• Liaise with customers, suppliers, manufacturing teams, and multidisciplinary stakeholders.
• Support project planning, estimating, and progress reporting activities.

Manufacturing & Continuous Improvement

• Support manufacturing, assembly, testing, and commissioning activities.
• Apply Design for Manufacture and Assembly (DFMA) principles throughout the design process.
