Technical Leadership

Act as the senior technical authority for manufacturing equipment and processes, providing direction on complex troubleshooting, root cause analysis and long-term technical solutions.

Lead the design, installation, qualification, optimisation and standardisation of lens production processes, equipment, tooling and controls, ensuring solutions are scalable and, where appropriate, deployed across multiple lines and value streams.

Drive year-on-year improvements in equipment OEE, process capability, yield and output through structured problem solving, data analysis and Lean / Six Sigma methodologies.

Develop and maintain technical roadmaps for assigned platforms, including obsolescence and aged-asset mitigation, technology upgrades and capability development.

Provide technical input to capital investment proposals, business cycle planning and cost-saving programmes.

Projects, NPI & Continuous Improvement

Lead large, cross-functional engineering projects from concept through design, installation, commissioning, validation and ramp-up, including new product introductions (NPI), line conversions and capacity expansion.

Identify and lead cost, quality and technical improvement initiatives under the site continuous improvement programme, quantifying benefits and delivering to agreed timelines and budgets.

Apply robust project management governance, providing timely and accurate status reporting to stakeholders and leadership.

Evaluate emerging technologies and industry trends, and introduce those that deliver a measurable benefit to safety, quality, delivery and cost.
