• Lead complex, multi-stage investigations across endpoint, identity, network, cloud, and SaaS telemetry, including advanced malware analysis, credential-compromise, and lateral-movement investigations.
• Define detection strategy aligned to MITRE ATT&CK and the organization’s threat model; identify and recommend new detection logic across SIEM, XDR, EDR, and SOAR.
• Conduct threat hunts guided by threat intelligence, emerging TTPs, and gaps in detection coverage; convert findings into new detections, playbooks, and control recommendations.
• Lead Tier 2 SOC operations, ensuring shift priorities, case load, and blocking issue flow meet SLAs and quality standards.
• Build and maintain SOC playbook, runbook, and knowledge-based library; ensure content stays current with tooling and threat changes.
• Identify, build, and recommend process improvements across the SOC, measuring and reporting their impact.
• Chip in to and help implement the multi-year security operations strategy, including detection coverage roadmap, telemetry strategy, automation targets, and capability maturity.
• Interpret security findings as risk-centered advice for security engineering, IT, and business collaborators.
• Mentor and develop Tier 1 and Tier 2 analysts through structured mentoring, investigation walkthroughs, and technical training.
• Participate in cross-functional forums and collaborate with global security teams to ensure a cohesive, consistent approach to security operations.
• Provide senior on-call coverage for major incidents involving blocking issues.

• Bachelor’s degree in Information Systems, Cybersecurity, or a related field, or equivalent experience.
• Advanced certifications such as GCIA, GCIH, GCFA, GCDA, GNFA, GREM, OSCP, Microsoft SC-200 or equivalent are highly regarded.
• Expert knowledge of Windows, Linux, Active Directory, and Entra ID charge techniques; able to reconstruct an intrusion from raw logs without a playbook.

• Proficiency in Python or PowerShell for automation, data analysis, and tooling integration.
• Deep solid understanding of MITRE ATT&CK, the incident response lifecycle, malware analysis, and phishing investigation.
• Track record of defining standards, processes, and playbooks, and of improving them based on evidence.
• Demonstrated ability to mentor analysts and raise the technical bar of a team.
• Clear, structured technical writing, including incident reports, RCAs, and briefings for senior technical and non-technical audiences.
