The role:

As a Deputy Security Metal Controller, you will help drive our goals by:

• Perform and witness key weighments in refining and chemicals processes, particularly at points of creation and consumption of high-risk materials (sponges and solid PGM); randomly check operator weighments and support monthly local stock checks.
• Review and analyse all weighment data to identify patterns, issues, and losses; assist in creating monthly stock and loss data, SPC outputs, and reports, including audit findings and recommendations for continuous improvement.
• Create, trial, and implement new weighment/control points to increase metal data and reduce business risk; conduct regular audits of metal production processes and apply SPC techniques to monitor compliance and process stability.
• Support development of semi-automated, data-logged witness-weighing systems (including liaison with Security and CCTV); work with the Security Metal Controller Lead and cross-functional teams to improve monitoring, secure systems of work, and refine production procedures across sites.

• Proficient in Microsoft Office, highly self-motivated, with strong time management skills and the ability to deliver effectively in a fast-paced environment.
• Able to learn complex operations, deliver innovative and practical solutions, and use data objectively to drive clear, unbiased decision-making.
• Strong communicator and collaborator, capable of building cross-functional relationships, seeing the wider business and customer context, and translating complex information into clear, concise summaries for both operational and technical audiences.
