The role focuses on proactive threat detection rapid incident handling and improved security posture across a complex multinational environment.
Responsibilities
- Monitor security events across Logrhythm SIEM AlertLogic SIEM Arcsight and IBM Qradar platforms to identify patterns that indicate potential threats and emerging attack campaigns
- Investigate security alerts in a structured manner by correlating events from multiple SIEM sources and documenting clear findings for rapid stakeholder understanding
- Develop PowerShell scripts to automate repetitive monitoring enrichment and reporting tasks that increase detection efficiency and reduce analyst workload
- Configure advanced correlation rules and tuning changes in Logrhythm SIEM to minimize false positives while preserving strong detection coverage for critical use cases
- Configure and optimize AlertLogic SIEM content to strengthen visibility into cloud workloads and network traffic and align detections with organizational risk priorities
- Enhance Arcsight use cases by refining filters thresholds and content updates that support consistent detection of suspicious or policy violating behavior
- Maintain and improve IBM Qradar parsers reference sets and custom rules to support high fidelity alerts and reliable incident prioritization across hybrid infrastructure
- Coordinate incident handling activities with internal technology and business teams by providing clear technical explanations containment guidance and remediation recommendations
- Document incident timelines root cause analysis and lessons learned in a clear and repeatable format that supports audit readiness and future control improvements
- Collaborate with infrastructure and application teams to validate log sources ensure complete onboarding into all SIEM platforms and close gaps in visibility across critical assets
- Support creation and refinement of security runbooks that define step by step responses for frequent incident types and help ensure consistent handling and reduced response times
