About the role

  • Implement and operate detection systems, including a scalable cloud-native SIEM platform supporting ingestion from identity, endpoint, SaaS, and infrastructure sources.
  • Develop and maintain detection coverage maps aligned to MITRE ATT&CK techniques, threat modeling, and incident history.
  • Leverage AI to accelerate detection rule creation, enrichment, and triage insights, and conduct AI-assisted threat hunting to surface novel behaviors and codify them as deterministic detections.
  • Build detection observability tools and dashboards to monitor rule effectiveness, alert volumes, and system performance.
  • Design and implement SOAR workflows and automated response playbooks with built-in observability, rollback, and reliability controls.
  • Leverage AI within SOAR for adaptive enrichment, workflow generation, and documentation, while continuously tuning automation based on incident outcomes.
  • Lead incident response activities as part of the incident commander rotation, and drive continuous improvement of runbooks and playbooks using lessons learned and AI support for timelines and summaries.
  • Collaborate cross-functionally with engineering and business stakeholders to embed detection and response into system design, operational processes, and organizational priorities.

Requirements

  • 5+ years in security engineering, detection engineering, or threat-focused automation roles.
  • Strong knowledge of MITRE ATT&CK framework, detection logic, and IOC/IOA patterns.
  • Familiarity with MITRE D3FEND for defense-in-depth and response playbook design.
  • Hands-on experience designing, deploying, or managing SIEM platforms (vendor-neutral mindset preferred).
  • Strong Python scripting skills for integrations, enrichment logic, and playbook development.
  • Experience working with structured data formats such as JSON, YAML, logs, and metrics.
  • Familiarity with SaaS logging constraints and cloud-native telemetry, preferably AWS.
  • Understanding of event-driven architecture and API-driven integrations.
  • Demonstrated ability to use AI tools to accelerate scripting, generate or translate detection rules, or assist with enrichment workflows, always with human validation for accuracy.
  • Comfortable working autonomously and cross-functionally to deliver reliable detection outcomes.
  • Preferred:
  • Experience building or maintaining detection pipelines using Elastic, Panther, or similar platforms.
  • Experience with detection-as-code practices, managing detection logic as version-controlled code with testing and CI/CD.
  • Experience writing detection rules in formats such as Sigma, including contributing to open-source or internal detection libraries.
  • Experience with MITRE frameworks: ATT&CK (adversary techniques), D3FEND (defensive techniques), and ATLAS (AI-related attacks).
  • Experience with OWASP guidance on application telemetry and detection (e.g., AppSensor, Logging Cheat Sheet).
