  • Advance our detection-as-code platform through version control, peer review, automated testing, CI/CD, and improved pipeline reliability and observability.
  • Identify emerging threat surfaces and build integrations that strengthen data ingestion, enrichment, and coverage across internal and third-party systems.
  • Evaluate AI-powered security capabilities, including secure MCP integrations, threat hunting, anomaly detection, and response automation.
  • Turn threat intelligence into actionable detection and retrospective scanning.
  • Partner closely with Security Operations during investigations, incidents, table top exercises, detection maintenance, and code pairing.
  • Champion Samsara’s cultural principles as we scale globally.

Qualifications

  • 6+ years in security engineering, detection engineering, or a related technology discipline.
  • Strong Python and SQL skills, with experience analyzing large datasets to build and validate detections.
  • Hands-on experience with detection-as-code, Git-based workflows, automated testing, and CI/CD deployment.
  • Deep experience with modern SIEM platforms, including data onboarding, advanced queries, dashboards, and threat intelligence enrichment.
  • Working knowledge of AWS, Linux, containers, and EDR.
  • Proven ability to build systems from scratch, lead projects independently, learn new technologies quickly, and communicate technical concepts clearly through documentation, RFCs, and presentations.
