[Hiring] Senior Security Engineer - Threat Detection @Samsara

Role Description

Samsara Security is looking for a Senior Threat Detection Engineer. This is a hands-on engineering role: you will build and operate the signals, pipelines, and tooling that power how we discover threats against Samsara and our customers.

• The Threat Detection team owns the detection platform end to end — the data pipelines that feed it, the detection content that runs on it, the CI/CD that ships it, and the AI-assisted tooling that scales what a small team can cover.
• You will write detections, and you will also build the machinery that makes the next detection faster to develop, safer to deploy, and measurable in production.
• You will report to the Director of Threat Detection and Response and work closely with Security Operations, Application Security, and Enterprise Security, as well as engineering teams across the company.
• We are looking for someone who takes projects from idea to proof-of-concept to production, who is comfortable being the first person to build something, and who is genuinely interested in what AI can and cannot do for detection engineering — including where it introduces risk rather than removing it.

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.

Requirements

• Experience with data orchestration platforms such as Airflow or Databricks.
• Applied experience with LLMs, agentic frameworks, and MCP integrations, including their security risks and failure modes.
• Experience with behavioral analytics, anomaly detection, feature engineering, and model evaluation.
• Familiarity with risk-based alerting, ChatOps, distributed alerting, and attack simulation.
• Additional experience with Go, Terraform, malware analysis, digital forensics, or FedRAMP environments.

Benefits

• Your efforts will result in real-world impact—helping to keep the lights on, get food into grocery stores, reduce emissions, and most importantly, ensure workers return home safely.
• If you put in the work, this role won't be your last at Samsara. We set up our employees for success and have built a culture that encourages rapid career development, countless opportunities to experiment and master your craft in a hyper growth environment.
• The vision we have to digitize large sectors of the global economy requires your full focus and best efforts to bring forth creative, ambitious ideas for our customers.
• At Samsara, we win together, celebrate together and support each other. You will be surrounded by a high-caliber team that will encourage you to do your best.
