Senior Security Engineer - Threat Detection
About The Position
Samsara Security is looking for a Senior Threat Detection Engineer. This is a hands-on engineering role where 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, including 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 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.
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.
Nice To Haves
- 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.
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.
Benefits
- Flexible, employee-led remote model
- Professional development stipend
- Comprehensive health and parental leave plans
- Above-market total compensation through a combination of base salary, performance-based bonus/variable pay, and equity (for eligible roles)
- Initial RSU grant with no vesting cliff, and ongoing refresh opportunities tied to performance
