We conduct thorough Baseline Personnel Security Standard (BPSS) checks as a precursor to all higher-level clearances.

Role Overview: We are establishing a modern Security Operations Centre designed to deliver proactive, intelligence-driven security outcomes. Moving beyond traditional reactive monitoring, our SOC emphasises AI, automation, detection engineering, and deep cloud security visibility to identify and neutralise sophisticated threats at scale.

The L3 SOC Analyst will act as the senior technical escalation point within the SOC, leading complex investigations, driving automation initiatives, and mentoring junior analysts. This role requires strong hands-on expertise across cloud security, threat hunting, incident response, and orchestration technologies.

Incident Response & Technical Escalation

Act as the final escalation point for complex incidents originating from L1/L2 analysis.

Lead investigations into high-severity security events, including those impacting AWS, Kubernetes clusters and hybrid environments.

Perform advanced forensic analysis across endpoints, cloud workloads, and network telemetry to determine root cause, impact, and remediation actions.

Correlate telemetry from SIEM, EDR, CSPM, and cloud-native sources to identify sophisticated attack chains.

Security Automation & SOAR Engineering

Design, develop, and maintain automated response playbooks within the SOAR platform to improve response efficiency.

Build and maintain automation scripts (Python, go, etc.) for alert enrichment, evidence collection, and containment.

Integrate security platforms via APIs to enable streamlined, automated detection and response workflows.

Identify opportunities to reduce Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR) through automation and process optimisation.

Threat Hunting & Detection Engineering

Conduct proactive threat hunting across enterprise and cloud environments using intelligence-driven and hypothesis-based methodologies.

Serve as an SME for cloud security monitoring leveraging tools such as AWS GuardDuty, CloudTrail, CrowdStrike, and Proofpoint.

Develop and tune SIEM detections, correlation rules, and EDR queries aligned to MITRE ATT&CK tactics and emerging threat intelligence.

Mentorship & Continuous Improvement

Provide technical mentoring and guidance to L1/L2 analysts to strengthen SOC capability.

Maintain and enhance SOC documentation including SOPs, runbooks, and response playbooks.

Analyse incident trends and operational metrics to recommend improvements in detection coverage, automation effectiveness, and security posture.

Bachelor’s degree in Computer Science, Cybersecurity, or related discipline (or equivalent industry experience).

Extensive experience in Security Operations with demonstrable time in a senior analyst, threat hunter, or L3 role.

Strong hands-on experience in cloud security monitoring and incident response across AWS - AWS experience is essential for this role.

Proven scripting and automation capability using Python, Go, PowerShell,Bash,etc.

Practical experience with SOAR platforms (e.g., CrowdStrike Fusion SOAR) and SIEM technologies (e.g., CrowdStrike Falcon, Splunk, QRadar, Microsoft Sentinel).

Deep understanding of EDR tooling, host/network forensics, and detection engineering practices.

Strong working knowledge of the MITRE ATT&CK framework and its application in threat detection and hunting.
