• Network & Digital Forensics: Collecting, preserving, and analyzing forensic evidence across heterogeneous network infrastructure, edge routers, switches, cloud environments, and specialized network functions.
• Incident Response Leadership: Serving as the technical lead during major security incidents-driving containment, root-cause analysis, threat eradication, and network recovery.
• Network Telemetry Analysis: Interrogating full packet captures (PCAP), NetFlow/IPFIX, firewall logs, and router/switch artifacts to trace adversary lateral movement and data exfiltration.
• Memory & Endpoint Forensics: Analyzing volatility memory dumps, volatile network state, process execution artifacts, and compromised system state during active intrusions to uncover malware execution, persistence mechanisms, and lateral movement tactics.
• YARA & Signature Engineering: Architecting, authoring, and maintaining custom YARA rules for memory analysis, file carving, binary inspection, and continuous endpoint/network artifact matching.
• Threat Hunting & Evidence Extraction: Proactively dissecting advanced persistent threat (APT) TTPs, extracting indicators of compromise (IOCs), and converting forensic findings into actionable detections.
• Automation & Forensic Tooling: Scripting automated artifact collection, evidence ingestion, and triage workflows to accelerate response timelines.
• Playbooks & Process Maturity: Develop and refine specialized DFIR playbooks and runbooks for high-impact security incidents (e.g., state-sponsored intrusions, ransomware, supply chain compromises, and DDoS events).
• Executive Reporting: Produce comprehensive, high-quality forensic investigation reports detailing attack timelines, root cause, evidence analysis, impact assessment, and technical remediation recommendations.

This role can be located in any US based Verizon hub location.
