We are looking for a highly skilled Senior or Principal SOC Analyst to play a key role in the detection, investigation, and response to advanced cyber threats within our Security Operations Centre.

• Act as the analyst "go-to" for questions, support and specialist analytical expertise
• Guide and mentor junior analysts, providing technical leadership during incidents
• Work with the analyst team to ensure proactive threat hunting using SIEM, EDR, and threat intel sources covers the pyramid of pain, and develops analysts into threat hunting beyond IoCs
• Analyse and validate security alerts, refining detection rules in collaboration with engineers
• Correlate signals from multiple platforms (e.g., EDR, network, cloud, identity) to identify adversary techniques (MITRE ATT&CK)
• Leverage threat intelligence (including MISP) to enrich investigations and build contextual awareness
• Contribute to detection use case development, helping to identify gaps in coverage and recommend improvements
• Support the evolution of incident response playbooks and knowledge base articles
• Collaborate with other teams to support vulnerability management, purple teaming, and security awareness activities
• Participate in the on-call rotation for high-priority escalations

• Strong working knowledge of:
- SIEM: Elastic Stack (Kibana, Logstash), Microsoft Sentinel
- EDR: Microsoft Defender for Endpoint, CrowdStrike Falcon, Elastic Defend
- Threat Intel: MISP (querying, correlation, pivoting)
- SOAR: Jira automations, Azure logic apps and logic functions
- Security Frameworks: MITRE ATT&CK, NIST, Cyber Kill Chain
• Proficiency in interpreting logs from systems, endpoints, cloud services (e.g., Azure, M365), and network sources
• Experience using threat intelligence to contextualise alerts and enhance response decisions
• Experience in developing and utilising hypothesis, analysis and iteration to drive results from threat hunting across the pyramid of pain
• Familiarity with threat hunting methodologies and anomaly detection approaches
• Ability to script or automate repetitive tasks (Python, PowerShell, or similar)
• Strong written and verbal communication skills for clear reporting and incident documentation
Desirable Skills
• Exposure to ITSM platforms like Jira (for incident workflows and automation)
• Experience with SOAR tools or Sentinel playbooks
• Participation in red/purple team exercises or incident simulation
