Job Description
At Samsara, we embrace a flexible working model that caters to the diverse needs of our teams.
Key Responsibilities
- 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.
- This role is open to candidates residing in the US except the San Francisco Bay Metro Area, NYC Metro Area, and Washington, D.C. Metro Area.
- 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.
Requirements
- 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.
- 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 & Perks
- At Samsara, we build for the people who keep the global economy moving. We want owners, not passengers, which is why our rewards are designed to fuel high-impact builders. Our compensation program delivers above-market total compensation through a combination of base salary, performance-based bonus/variable pay, and equity (for eligible roles) in a high-growth public company. We meaningfully differentiate pay for our top performers, who have the opportunity to earn above-market compensation that can outpace the broader market over time.
- Beyond compensation, we provide the foundations that enable long-term success: a flexible, employee-led remote model, a professional development stipend, comprehensive health and parental leave plans, and more. If you’re ready to build for the long term and own the outcome, your journey starts here.
