We are seeking a Senior Cyber Security Analyst to act as deputy to the Group Head of Cyber Resilience and Security. This is a hands-on role combining security operations, incident response, vulnerability management, identity security, cyber risk and governance.

You will investigate and coordinate security incidents, manage vulnerabilities, assess cyber risk across projects and third parties, and help strengthen security controls and resilience. You will also provide technical guidance to other analysts and represent the Security function with key stakeholders.

Key responsibilities:

  • Lead and investigate security incidents, coordinating containment and remediation.

  • Use SIEM, EDR, Microsoft Defender and Sentinel to investigate suspicious activity.

  • Manage vulnerability assessment, prioritisation and remediation.

  • Conduct cyber risk assessments across projects, systems and third parties.

  • Support ISO 27001, Cyber Essentials and security governance.

  • Work across Entra ID, Conditional Access, Active Directory and IAM.

  • Drive improvements to security controls, processes and cyber resilience.

  • Support and mentor less experienced analysts and act as a senior escalation point.

About you:

  • Strong hands-on experience across security operations and incident response.

  • Good knowledge of Microsoft security technologies, with KQL/Sentinel experience desirable.

  • Strong understanding of IAM, endpoints, networking, cloud and enterprise security.

  • Practical vulnerability management and cyber risk assessment experience.

  • Experience with ISO 27001, Cyber Essentials or similar frameworks.

  • Strong communication skills and confidence working with technical and senior stakeholders.

Certifications such as CISSP, CISM, SSCP, CySA+, BTL1/BTL2 or SC-200 are desirable, but practical experience is the priority.
