Lead Threat Hunter

Key Responsibilities

• Lead hypothesis-driven, intelligence-led hunt campaigns from formulation through reporting, mapped to MITRE ATT&CK
• Design and execute custom analytics against large-scale security telemetry (SIEM, EDR/XDR, identity, cloud, network) to uncover adversary tradecraft that evades existing detections
• Perform identity-centric hunting across Entra ID, Active Directory, and SaaS platforms - token theft, session hijacking, MFA bypass, OAuth abuse, and conditional access circumvention.
• Conduct cloud-native hunting across AWS, Azure, M365, and SaaS control planes, including audit logs, identity events, and workload telemetry.
• Convert hunt findings into durable detections, signatures, and SOAR playbooks in partnership with Detection Engineering, closing the hunt-to-detect loop
• Perform Deception Operations by defining adversary-aligned use cases, authoring detection requirements for deception-generated activity, and tuning signal vs. noise thresholds
• Leverage AI and LLM-assisted tooling to accelerate hunting - including query generation, log summarization, entity pivoting, anomaly clustering, and large-scale pattern discovery across disparate telemetry sources
• Hunt within AI and LLM environments - including enterprise copilots, internal/external LLM deployments, AI agents, RAG pipelines, model endpoints, and AI/ML infrastructure - for threats such as prompt injection, model abuse, data exfiltration via AI channels, agent hijacking, supply-chain compromise of models, and unauthorized model access
• Produce post-hunt reports with explicit evidence and measurable outcomes tied to exposure reduction
• Partner with Threat Intelligence to operationalize finished intel into targeted hunt missions and feed collection requirements upstream
• Support purple team exercises and validate detection efficacy against adversary emulation campaigns (Atomic Red Team, CALDERA, Stratus Red Team)
• Develop and maintain custom tooling and automation to support hunting, investigation, and analyst efficiency
• Mentor junior hunters; contribute to internal knowledge bases, hunt libraries, and team training
• Support Incident Response, Forensics, and Insider Threat/Fraud investigations as a senior technical resource when adversary expertise is needed
• Serve as a liaison for Threat Services across Cyber Operations, communicating findings clearly to technical peers and executive leadership
• Identify needs, drive solutions, and operate autonomously within strategic priorities
• Identify visibility and telemetry gaps discovered during hunts and partner with engineering teams to improve enterprise collection coverage
• Develop behavioral, anomaly-based, and baseline-deviation hunt methodologies beyond known ATT&CK tradecraft

Required Qualifications

• 7+ years of experience in security operations with 4+ of those years dedicated to threat hunting
• Deep experience hunting in large, complex enterprise environments
• Demonstrable experience executing MITRE ATT&CK-aligned hunts with documented outcomes and detection handoffs
• Hands-on experience with modern SIEM (Splunk, Sentinel, Elastic) and EDR/XDR (CrowdStrike, Defender, SentinelOne, Tanium)
• Demonstrated experience using AI/LLM-assisted tooling (e.g., Security Copilot, custom GPTs, agentic workflows, embeddings-based analytics) to accelerate hunting, triage, and analytic development.
• Working knowledge of hunting in AI/LLM environments - familiarity with the MITRE ATLAS framework, OWASP Top 10 for LLM Applications, and common AI-specific threats (prompt injection, model theft, training data poisoning, agent abuse, sensitive data leakage through AI channels)
• Working knowledge of threat intelligence frameworks: Diamond Model, Kill Chain, and the Pyramid of Pain
• Strong scripting and automation skills in Python, PowerShell, GO, and/or Bash
• Deep understanding of common network and application stack protocols: TCP/IP, DNS, TLS, HTTP, SMTP, etc.
• Experience with signature and analytic development: CQL/KQL/SPL analytics, Sigma, YARA, Snort/Suricata
• Excellent analytical and problem-solving skills, with a research mindset and a passion for puzzles
• Strong written and verbal communication, including the ability to produce executive-ready summaries of technical findings
• Demonstrated leadership and mentorship capability
• Strong motivation to understand and train in new technologies, techniques, and a self-starter
• Demonstrated ownership of end-to-end hunting programs, including hypothesis generation, data source evaluation, hunt execution, findings analysis, stakeholder communication, and measurement of outcomes
