Principal Threat Hunting and Emulation Engineer - InfoSec

Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale — unleashing the potential of businesses and people. The Elastic Search AI Platform, used by more than 50% of the Fortune 500, brings together the precision of search and the intelligence of AI to enable everyone to accelerate the results that matter. By taking advantage of all structured and unstructured data — securing and protecting private information more effectively — Elastic’s complete, cloud-based solutions for search, security, and observability help organizations deliver on the promise of AI.

What Is The Role :

What You Will Be Doing :

• Lead structured, hypothesis-driven threat hunting operations across Elastic’s cloud, SaaS, endpoint, and CI/CD environments using frameworks such as PEAK, TaHiTI, or equivalent.
• Develop and maintain a threat hunting program at scale. Defining hunt hypotheses based on threat intelligence, ATT&CK mappings, and environmental risk profiles.
• Design and execute adversary emulation exercises and purple team engagements to validate detection pipelines, identify coverage gaps, and simulate real-world threat actor TTPs.
• Build and maintain a threat emulation library of reusable attack simulations, leveraging tools such as Atomic Red Team, Caldera, Scythe, or custom-developed tooling.
• Leverage AI and machine learning capabilities to accelerate hypothesis generation, anomaly detection, and the analysis of large, complex datasets during hunts.
• Translate hunt findings into production-ready detections, collaborating closely with Detection Engineering to ensure durable coverage.
• Document and codify hunt methodologies, playbooks, and emulation plans so that findings are repeatable, reviewable, and transferable.
• Partner with Threat Intelligence to inform hunt hypotheses based on emerging adversary campaigns, newly disclosed vulnerabilities, and sector-specific threat profiles.
• Identify visibility gaps exposed through hunting and emulation, and collaborate with Security Engineering to onboard the log sources needed to close them.
• Support incident response activities by applying hunting skills to accelerate investigation, scope incidents, and identify attacker dwell time or lateral movement.
• Contribute to the broader security community through blog posts, conference talks, open-source tooling, and other public knowledge sharing.

What You Bring :

• At least 8 years of experience in information security with a focus on threat hunting, detection engineering, incident response, or red/purple team operations with the Elastic Stack.
• Demonstrated experience in conducting structured and hypothesis-driven threat hunts in complex enterprise or cloud-native environments. The focus is on forward-thinking threat hunting, not just reactive investigation.
• Familiarity with threat hunting frameworks such as PEAK, TaHiTI, or Sqrrl, and the ability to apply them operationally and at scale.
• Experience designing and executing adversary emulation exercises or purple team engagements, including scoping, execution, and post-exercise reporting.
• Working knowledge of adversary TTPs through frameworks such as MITRE ATT&CK, and the ability to map real-world threat intelligence to hunt hypotheses.
• Experience using AI-assisted tooling or large language models to support threat hunting workflows, such as hypothesis generation, log summarization, or anomaly triage.
• Scripting or coding ability to automate repetitive hunt tasks or build custom tooling.
• A curious, research-driven mindset. You read threat reports, study malware, and seek to understand attacker behavior at a deep level.
• Strong written communication skills with an ability to document technical findings clearly for both technical and executive audiences.
• Is eligible to work in Department of Defense (DoD) Impact Level 4 or above cloud service environments.

Bonus Points :

• Background in both detection engineering and incident response—understanding how hunts feed detections and how incidents inform future hunts.
• Experience threat hunting in cloud environments (AWS, GCP, Azure).
• Familiarity with CI/CD and developer supply chain threat hunting (GitHub Actions, code pipeline integrity, dependency confusion, etc.).
• Contributions to open-source threat hunting or detection engineering projects, or public threat research publications.
