About the role

You’ll guide, coach and uplift teams to build a culture where cyber awareness feels empowering, not intimidating, and where every site feels supported and ready for the future. You will partner closely with operators, site managers, and trusted third‑party integrators. You will develop assured approaches to working, nurture standard methodologies, and champion a joined‑up approach to cyber resilience.

From shaping training and standards, to coordinating emergency response, and providing calm, expert leadership when it matters most, you will be the steady, supportive presence that keeps our operations not just moving, but thriving. If you love combining technical depth with people-focused influence, this role gives you the space to make a real and lasting impact.

Key accountabilities include:

• Lead and embed Operational Technology Cyber Security standards across operational sites, driving compliance, governance and knowledge uplift.
• Partner with Site Managers, Operators and Integrators to coordinate cyber‑secure maintenance planning, ensuring SAP‑PM tasks, PPMs and resource needs are fully aligned to production schedules.
• Provide expert incident and emergency coordination as the SME, ensuring swift response to any blocking issue and effective 24/7 support.
• Collaborate with third‑party integrators to ensure assured methods of operation, strong alignment to Diageo standards and continuous improvement across hardware, software and processes.
• Analyse data and Cyber Security benchmarks to build improvements, improve risk assessments and drive performance across your sites.
• Support team development and training plans, coaching colleagues and building confidence in cyber‑secure behaviours.
• Oversee Management of Change, Business Continuity and Disaster Recovery processes, as well as secure remote access and controlled environment requirements for OT equipment.
• Participate in routine Cyber Security review meetings, bringing data‑driven insight and a collaborative, solutions‑focused approach.
