This role operates at a senior or L3 capability level within the Security Operations Centre. You will act as a key escalation point for complex security events, lead high-impact investigations, improve detection and response capability, and provide technical guidance to analysts across the team. You will report to the Cyber Operations Team Lead and work closely with analysts at all levels, incident response leads, and cross-functional stakeholders including Group GRC.

Lead investigation and response to complex or high-severity security incidents, acting as the senior escalation point for SOC analysts.
-
Conduct advanced threat hunting across enterprise, endpoint, identity, network, and cloud environments.
-
Develop, tune, and improve detections across SIEM, EDR/XDR, cloud security, and identity platforms.
-
Support digital forensic investigations, including endpoint, disk, memory, network, identity, and cloud evidence analysis.
-
Develop automation and identify practical AI-assisted improvements across SOC workflows, including alert enrichment, triage, containment, reporting, and knowledge management.

Improve incident response playbooks, runbooks, escalation criteria, and operating procedures.
-
Build and maintain effective working relationships with Group GRC, supporting governance, compliance, and control validation activities as they relate to security operations.
-
Produce clear investigation notes, incident reports, root cause analysis, and executive-ready summaries.
-
Mentor junior and mid-level analysts through coaching, peer review, and knowledge sharing.
You are an experienced cyber security operations professional who takes ownership of complex investigations, makes sound decisions under pressure, and guides others during incidents. You are comfortable working across technical domains and can translate detailed findings into clear, actionable outcomes.
You Will Bring
-
Significant hands-on experience in cyber security operations, SOC analysis, incident response, threat hunting, detection engineering, or a closely related field, operating at a senior analyst or L3 escalation level.
