L3 SOC Analyst

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.

What You Will Do

• 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.
