Job summary

Qualifications

• 6+ years in security 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.

Responsibilities

• Build, deploy, and continuously improve MITRE ATT&CK–aligned detections across cloud, endpoint, identity, email, and application telemetry, with clear false‑positive thresholds.
• Own the full detection lifecycle—from hypothesis, data validation, and baselining through deployment, tuning, validation, and retirement.
• 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, role model, and embed Samsara’s cultural principles (Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team) as we scale globally and across new offices.
