Job Duties:
Operationally develop, deploy, and maintain high‑fidelity detections across SIEM, EDR, and other security telemetry platforms to support continuous monitoring and response.
Work closely with the Detection & Response team to validate alerts, refine workflows, and ensure engineered detections align with operational needs and real‑world analyst workflows.
Provide rapid detection‑focused support during active incidents, including tuning recommendations, data enrichment, and technical guidance for investigation teams.
Conduct ongoing tuning and optimization to improve detection fidelity, reduce false positives, strengthen efficiency, and close visibility gaps across the enterprise.
Perform advanced threat and telemetry analysis to confirm detection performance, identify adversary behaviors, and ensure coverage of emerging threats.
Operationalize Cyber Threat Intelligence (CTI) by translating observed TTPs, indicators, and behavioral patterns into reliable, actionable detections aligned with DCO mission requirements.
Partner with CTI, Offensive Security Operations (OSO), and Purple‑Team operators to validate detection logic through adversary emulation, exercise detection coverage, and refine monitoring gaps identified during testing.
Convert threat‑hunting discoveries, vulnerability insights, and purple‑team findings into improved detection logic, analytics, and monitoring enhancements.
Maintain clear documentation for detection logic, tuning actions, workflows, and operational standards to support consistency and repeatability across the SOC.
Mentor Detection Engineering analysts and support development of Detection & Response personnel to strengthen operational capability and readiness.
Contribute to ESOC/DCO improvement initiatives, including engineering sprints, automation efforts, detection content onboarding, and process refinement.
Lead post‑incident detection reviews to identify root‑cause gaps, update detection coverage, and improve overall defensive posture.
Enhance dashboards, analytics, and tooling used across ESOC to support monitoring, triage, and investigative operations.
Support the ESOCs 24/7/365 operational needs as required to maintain continuity of coverage during high‑priority or elevated‑tempo events.
Perform additional duties and support other operational tasks as assigned to meet mission and organizational needs.
