Senior Security Analyst (L3 SOC Analyst)
We are seeking a Senior Security Analyst (L3 SOC Analyst) to provide advanced security monitoring, investigation, and incident response within a fast-paced Security Operations Centre. In this role, you will act as a senior escalation point for complex and high-impact security events, helping to protect critical systems, applications, networks, and data. You will investigate sophisticated threats, determine root cause, assess business impact, and coordinate appropriate containment and remediation activities.
Your responsibilities will include analysing alerts and telemetry from SIEM, EDR, network security, identity, cloud, and vulnerability management platforms; leading investigations into suspected compromise, malware, insider threats, credential abuse, and data exfiltration; and developing detailed incident timelines and technical reports. You will validate detection logic, improve correlation rules and use cases, support threat hunting, and contribute to the development and maintenance of playbooks and response procedures. You will also mentor junior analysts, provide guidance on complex investigations, participate in incident reviews, and work closely with infrastructure, engineering, risk, and compliance teams to strengthen the organisation’s security posture.
The successful candidate will have substantial experience in a SOC, incident response, digital forensics, threat detection, or a closely related security function, with proven capability operating at an L3 or senior level. You should have strong knowledge of security monitoring principles, attack frameworks such as MITRE ATT&CK, common exploitation techniques, and investigative methods across endpoint, network, cloud, and identity environments. Experience with SIEM and EDR technologies, scripting or automation using tools such as Python or PowerShell, and security operations in cloud platforms is highly desirable. Excellent analytical, written, and verbal communication skills are essential, along with the ability to remain calm under pressure, manage competing priorities, and make sound decisions during critical incidents. Relevant certifications such as GIAC, CISSP, or equivalent professional experience would be advantageous.
