Job Overview As a Senior SOC Analyst, you will serve as a technical escalation point within the SOC, lead complex investigations, and help advance the SOC's risk-driven detection and response capabilities. The role combines day-to-day security operations with deeper expertise in at least one of the following areas: Advanced Incident Response, Threat Hunting, SIEM Automation, or Detection Engineering.

You will independently handle complex work, mentor analysts, and translate incidents, threat intelligence, and business risks into improved use cases, detections, hunts, and automated workflows. The successful candidate should have at least three years of hands-on experience in one or more of these specialty areas; broader or multi-domain experience is preferred.

Key Responsibilities

- Serve as a senior technical escalation point for complex or high-impact security alerts and incidents, validating severity, scope, business impact, and required escalation.
- Lead security incidents through the investigation life cycle, including scoping, evidence collection, containment and remediation guidance, root-cause analysis, status reporting, and lessons learned.
- Conduct proactive threat hunting using hypotheses derived from threat intelligence, incident findings, attacker behaviours, environmental risk, and known detection gaps; document methods, evidence, and outcomes.
- Own or lead the security use case life cycle by identifying and prioritizing detection needs based on threats and business risks; defining objectives, data sources, logic, response actions, ownership, testing, and review requirements; and driving tuning, improvement, or retirement.
- Design, develop, test, validate, and tune SIEM, endpoint, or other security detections; identify coverage gaps and map detection logic to relevant threat behaviours or frameworks.
- Design, test, document, and maintain SIEM/SOAR automation and orchestration workflows that improve investigation and response consistency, reduce repetitive manual effort, and preserve appropriate approvals and audit trails.
- Translate incident, threat-hunting, and threat-intelligence findings into new or improved detections, use cases, playbooks, automation, and recommendations for security controls.
- Review use case, detection, and automation performance using operational metrics and analyst feedback,



and recommend improvements to alert quality, coverage, investigation efficiency, and response effectiveness.
- Mentor SOC Analysts, support complex investigations, and perform peer review of queries, detections, playbooks, automation, and investigation findings when appropriate.
- Maintain clear procedures, playbooks, knowledge articles, investigation records, and shift handoff documentation to support repeatable and auditable SOC operations.
- Stay current on cybersecurity threats, attacker techniques, technologies, and best practices, and apply relevant developments to SOC monitoring and detection strategy.
- Support routine monitoring and response across SIEM, EDR, email security, DLP, network security, and other SOC technologies when required.
- Support the maintenance of the Information Security Management System (ISMS) by following corporate policies and providing supporting evidence for audits when required.
- Additional responsibilities as assigned.
