As the Principal Lead Analyst of DART, you are the ultimate technical authority for cyber defense and incident response. This is a high-impact leadership role that combines elite-level technical expertise with strategic vision. You will oversee the most complex security breaches, drive the evolution of our threat-hunting program, and mentor the next generation of responders. You are responsible for ensuring that the organization is not just "ready" for a crisis, but resilient enough to withstand one. This role partners closely with Cyber Intelligence, Defense and Response, Application Security, and Cyber Resilience teams, and supports incident response efforts as an expert resource on adversarial capabilities.

Requirements

• 8+ years in Cybersecurity, with at least 5 years in a dedicated Incident Response or DFIR role.
• Proven experience leading response efforts for a large-scale enterprise or a top-tier IR firm (e.g., Mandiant, CrowdStrike).
• Solid understanding of deep-system forensics (Memory, Disk, Network) and specialized experience in Cloud IR (Azure/AWS/O365).
• Deep familiarity with enterprise forensic platforms (Nuix, Magnet AXIOM, EnCase) and the ability to guide L2 analysts in their usage.
• Expert-level understanding of TTPs (Tactics, Techniques, and Procedures) used by both state-sponsored and financially motivated (Ransomware) threat actors.
• High proficiency in automation (Python, PowerShell) to build custom response scripts or API integrations between security tools.

• Advanced SANS: GCFA (Forensics), GNFA (Network Forensics), GREM (Reverse Engineering Malware), or GXPN (Exploit Researcher).
• Leadership: CISSP-ISSMP (Management) or GCIH (Incident Handler).
• Decisiveness: The ability to make $1M+ decisions (e.g., "Shut down this data center now") with limited information during a live attack.
• Political Acumen: Skill in navigating the complexities of a large organization, working with Legal, Privacy, and Human Resources during sensitive internal investigations.
• Resilience: Unwavering composure during high-stress, 24/7 incident cycles.

Responsibilities

• Serve as the primary Incident Commander for all Tier 3/Critical-level events. You will direct the technical response across all workstreams (Forensics, Network, Cloud, Legal, and PR).
• Act as the technical voice for executive leadership. You must be able to translate complex exploit chains and technical risks into business-impact narratives for the C-Suite and Board of Directors.
• Lead "Purple Team" exercises to test DART’s readiness against specific APT (Advanced Persistent Threat) groups and real-world attack scenarios.
• Design and oversee the organization’s long-term threat-hunting roadmap, ensuring coverage across the MITRE ATT&CK framework for Cloud (Azure/AWS), Identity, and On-Prem infrastructure.
• Collaborate with engineering teams to ensure that hunt findings are converted into high-fidelity, automated detections and SOAR (Security Orchestration, Automation, and Response) workflows.
• Direct the consumption of tactical and strategic Threat Intelligence to proactively "harden" the environment before a known threat actor targets the industry.
• Elevate the entire SOC/DART capability by providing technical mentorship to L1 and L2 analysts. You are responsible for the technical "QA" of the team’s investigative output.
• Evaluate and select next-generation forensic and response technologies. You will drive the business case for new security investments.
