69d•Onsite

About The Position

Lead complex, hypothesis-driven threat hunts across multiple enterprise data sources and enclaves to identify sophisticated or previously undetected adversary activity. Proactively analyze security telemetry to identify indicators of compromise, anomalous behavior, and adversary activity that has not met an incident threshold or has evaded automated security controls. Assess and correlate data from multiple sources, including network, endpoint, identity, SIEM, threat intelligence, vulnerability, and other available security data. Document hunt activity, findings, evidence, and recommended follow-on actions in authorized systems and initiate or support incident-response processes when malicious activity is identified. Provide relevant findings and trends for SOC operational reporting, significant-activity reporting, and defensive awareness. Develop and prioritize hunt campaigns based on threat intelligence, mission risk, adversary TTPs, detection coverage, incident lessons learned, and environmental changes. Perform advanced behavioral analysis and identify patterns indicative of persistence, credential abuse, lateral movement, command and control, collection, or other adversary activity. Serve as an escalation point for junior threat analysts and provide technical guidance on hunt methodology, analytical pivots, and evidence validation. Translate successful hunt findings into actionable requirements for detection engineering, watch operations, security engineering, and incident response. Develop reusable hunt playbooks, queries, analytic methods, documentation standards, and training materials. Mentor junior personnel and support exercises, knowledge sharing, and assessment of threat-analysis proficiency.
