· Translate technical telemetry, forensics, intelligence reporting, and analytic findings into clear, actionable technical, operational, and executive-level summaries; prepare and deliver recurring and on-demand briefings to leadership, tenant organizations, and mission partners.

· Serve as a subject matter expert on adversary tradecraft and provide threat context, intelligence support, and analytic recommendations to incident responders and other SOC teams during active investigations.

· Develop and maintain SOPs, work instructions, hunt methodologies, analytic playbooks, detection use cases, and knowledge-management artifacts; identify capability and workflow gaps, recommend improvements, and enhance automation for enrichment, case management, reporting, dashboards, and metrics.

· Hands-on experience conducting hypothesis-driven threat hunts, developing detection logic and analytic queries, and pivoting from external threat reporting, IOCs, and OSINT to internal enterprise telemetry.

· Demonstrated experience querying, analyzing, and correlating high-volume SIEM, EDR, endpoint, network, NetFlow, packet, log, and other host- or network-based security data; working knowledge of TCP/IP, common ports and protocols, network traffic flow, OSI model, system administration, defense-in-depth, and enterprise security architecture.

· Strong written, verbal, analytical, and collaboration skills, including the ability to produce technical and executive-level reports and briefings; ability to work independently, manage competing priorities, and work effectively with technical and non-technical mission partners.
