• Oversee security transformation projects, ensuring seamless migration from legacy solutions to new platforms and processes.
• Work closely with internal stakeholders and external partners to ensure compliance with industry standards and customer SLAs.
• Conduct ongoing security assessments, identifying vulnerabilities and recommending strategic improvements.
• Lead and mentor on-site security teams, instilling a culture of accountability, resilience, and continuous improvement.
• Provide senior-level reporting on risks, incidents, and project progress to Executive Leadership.
• Support major operational change initiatives, including new site commissioning, upgrades, and facility expansions.

Required experience:

• Proven experience in a senior physical or operational security leadership role, ideally within Data Centres, critical infrastructure, or similarly high-assurance environments.
• Strong experience managing security transformation or transitional security programmes.
• Deep understanding of physical security systems, access control, compliance frameworks, and incident management.
• Excellent stakeholder management skills, able to influence at all levels and operate confidently in fast-moving environments.
• Strategic, structured, and proactive mindset, with the confidence to lead organisational change.
• Relevant security certifications or industry qualifications are highly desirable.
