Desirable

• Lead the team: Build, mentor and manage the performance of a Security Operations team across the UK and Australia, creating an environment of continuous learning, clear ownership and psychological safety
• Evolve incident response: Develop our incident response processes, especially around AI, maintain playbooks and standard operating procedures, and run exercises that build team confidence when it matters most
• Hunt threats: Proactively hunt for threats before they become incidents, and work with penetration testers, red teams and bug bounty programmes to find weaknesses, then partner with security engineering and technology teams to close gaps
• Own detection and tooling: Own our security monitoring and detection capability, including SIEM, EDR and threat intelligence platforms, driving the tooling roadmap, tuning detections to cut noise, and championing automation
• Report on what matters: Define and own Security Operations KPIs and KRIs, and give senior stakeholders clear reporting on the health of the function, including mean time to detect, mean time to respond and coverage trends
• Support compliance and governance: Make sure our security operations posture supports our regulatory and contractual obligations, acting as a key stakeholder in audits, assessments and customer security reviews, and working closely with Legal, Compliance and Privacy
