About the Job

Requirements

  • At least 7 years of experience in security operations, including at least 4 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 security information and event management platforms such as Splunk, Sentinel, or Elastic, and endpoint detection and response platforms such as CrowdStrike, Defender, SentinelOne, or Tanium.
  • Demonstrated experience using artificial intelligence and large language model-assisted tooling, such as Security Copilot, custom GPTs, agentic workflows, or embeddings-based analytics, to accelerate hunting, triage, and analytic development.
  • Working knowledge of hunting in artificial intelligence and large language model environments, including familiarity with the MITRE ATLAS framework, OWASP Top 10 for LLM Applications, and common AI-specific threats such as prompt injection, model theft, training data poisoning, agent abuse, and sensitive data leakage through AI channels.
  • Working knowledge of threat intelligence frameworks, including the Diamond Model, Kill Chain, and Pyramid of Pain.
  • Strong scripting and automation skills in Python, PowerShell, Go, and/or Bash.
  • Deep understanding of common network and application stack protocols, including TCP/IP, DNS, TLS, HTTP, and SMTP.
  • Experience with signature and analytic development, including CQL/KQL/SPL analytics, Sigma, YARA, and Snort/Suricata.
  • Strong analytical and problem-solving ability, a research mindset, and an interest in investigative problem solving.
  • Strong written and verbal communication, including the ability to produce executive-ready summaries of technical findings.
  • Demonstrated leadership and mentorship capability.
  • Motivation to learn and train in new technologies and techniques, and ability to work independently.
  • Demonstrated ownership of end-to-end hunting programs, including hypothesis generation, data source evaluation, hunt execution, findings analysis, stakeholder communication, and outcome measurement.

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, including SIEM, EDR/XDR, identity, cloud, and network data, to uncover adversary tradecraft that evades existing detections.
  • Perform identity-centric hunting across Entra ID, Active Directory, and SaaS platforms for 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-to-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 and 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, model supply-chain compromise, 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 intelligence into targeted hunt missions and feed collection requirements upstream.
  • Support purple team exercises and validate detection efficacy against adversary emulation campaigns using Atomic Red Team, CALDERA, and Stratus Red Team.
  • Develop and maintain custom tooling and automation to support hunting, investigation, and analyst efficiency.
  • Mentor junior hunters and 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 and communicate 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.

Desired Qualifications

  • Proficiency in KQL/CQL/SPL and comfort building complex queries and analytics across large datasets.
  • Experience hunting in cloud environments such as AWS, Azure, and M365 using native telemetry such as CloudTrail, Azure Activity, M365 Unified Audit Log, and identity provider logs.
  • Adversary emulation experience using Atomic Red Team, CALDERA, Stratus Red Team, or equivalent.
  • Recent experience with malware analysis and reverse engineering.
  • Hands-on experience securing or hunting within AI/ML pipelines, model registries, vector databases, and agentic systems.
  • Hands-on experience with vulnerability research, penetration testing, or exploit development.
  • Experience with container and Kubernetes security telemetry, including Falco, runtime security, and cloud workload protection.
  • Experience consuming deception technology outputs as a hunting data source.
  • Familiarity with threat hunting maturity models such as the Hunting Maturity Model (HMM), and ability to advance program maturity.
  • Experience with insider threat or fraud-adjacent hunting use cases.
  • Published research, conference talks, CTF participation, or contributions to open-source detection content such as Sigma rules, Atomic Red Team, or hunt libraries.
  • Familiarity with OT/ICS or IoT environments.
  • Relevant certifications such as GIAC GCTD, GCTI, GCFA, GCFE, GNFA, GREM, GDAT, or GCIA; offensive certifications such as OSCP, OSCE, or CRTO; cloud certifications such as AWS Security Specialty, AZ-500, or SC-200; AI/ML security certifications, MITRE ATLAS training, or AI red-team credentials; or foundational certifications such as CISSP or CEH.
  • Tool-specific certifications in Splunk, Sentinel, CrowdStrike, or similar platforms.
