About the role

  • Oversee security event triage, validation, and response workflows; ensure timely investigation of high-priority alerts and anomalies.
  • Collaborate with detection engineering and threat intelligence to refine investigative signals and improve visibility.
  • Maintain incident management processes, categorize, document, and escalate incidents as needed; ensure adherence to playbooks and compliance standards (CISA, GDPR, NIST, ISO 27001).
  • Perform continuous operational improvements: tune detection rules, optimize log ingestion, and enhance alert enrichment pipelines.
  • Conduct security gap analysis and work with engineering to improve log collection, normalization, and visibility across environments.
  • Lead forensic investigations into intrusions, insider threats, APTs, and account compromises; perform disk, memory, and network forensics.
  • Perform log analysis, correlation, and anomaly detection across endpoint, network, and cloud telemetry; use Python and SQL to extract insights from large-scale logs.
  • Investigate real-time security incidents and conduct post-incident root cause analysis with documentation and mitigation recommendations.
  • Oversee security monitoring operations, optimize SIEM queries, log pipelines, and case management to improve threat visibility.
  • Develop playbooks, SOPs, and automated solutions (log parsing scripts, enrichment tools, case correlation) to streamline investigations.
  • Build log analysis pipelines, custom detection logic, and scalable solutions for PCAP analysis, network flow monitoring, and cloud event detection.
  • Correlate multi-source logs and use threat intelligence APIs (VirusTotal, AbuseIPDB) to enrich investigations and automate IOC processing.

Requirements

  • 3+ years of experience in incident response, security operations, and forensic analysis.
  • Proven ability to lead crisis situations and make data-driven security decisions.
  • Strong expertise in incident management, root cause analysis, and forensic investigation methodologies.
  • Hands-on experience with SIEM (SQL, ELK), SOAR, and EDR (CrowdStrike) for real-time monitoring and response.
  • Expertise in cloud security (AWS, GCP, Azure) and containerized workloads (Kubernetes, Docker) security incident handling.
  • Experience managing large-scale security incidents with effective escalation and business alignment.
  • Proficiency in OKR methodologies, Agile workflows, and project prioritization strategies.
  • Strong understanding of threat intelligence, attacker tactics (MITRE ATT&CK), and real-world attack chains.
  • Proficiency with Python, SQL, and data engineering techniques for large-scale log analysis.
  • Participation in a shared on-call rotation with rotating weekend and holiday shifts.
  • Nice-to-have: Certifications GCFA, GNFA, GREM, GCIH or equivalent.
  • Nice-to-have: Familiarity with SOAR platforms and security case management automation.
  • Nice-to-have: Experience in Red Teaming, Threat Intelligence, or Malware Analysis.
  • Nice-to-have: Understanding of cloud-native security monitoring (AWS, GCP, Azure).
