Senior Security Engineer - Enterprise Security

About the role:

The Senior Security Engineer – Enterprise Security shares ownership of the day-to-day operation of the Samsara security environment. You will keep our network access, device trust, and visibility systems running, tuned, and resilient at enterprise scale in partnership with a global team. Utilizing modern principles, you’ll maintain and evolve a modern zero trust program, spend time both on policy design and real-time triage for escalations.

You take security seriously and believe the best solutions are low-friction and built in partnership with others. You are comfortable owning and maintaining production systems for long term success - troubleshooting systemic issues, tuning policies based on real incidents, and continuously improving what is already built. You bring an automation mindset to repetitive work, whether using Python, SOAR platforms, or AI-assisted tools. You enjoy supporting teammates and helping other engineers build their security knowledge.

This is a remote position open to candidates residing in the United Kingdom. Relocation assistance will not be provided for this role.

About this team:

Enterprise Security is a global team spanning the US, EMEA, and India. We work in close partnership with our coworkers as collaborators rather than gatekeepers. Leadership is hands-on and technical, and our culture encourages everyone to contribute across the full stack.

Executive leadership actively champions security as a competitive advantage that builds customer trust and helps win enterprise partnerships. You will see a direct line between the zero trust systems you operate and the security that protects our physical operations partners worldwide. Our on-call rotation for the highest severity incidents is spread evenly across the team for one week out of every ten.

In this role, you will:

• Co-own the day-to-day operation, triage, and tuning of the Samsara endpoint security environment by responding to escalations, investigating anomalies, and resolving issues
• Continuously improve existing endpoint visibility tools and workflows in partnership with our Security Operations team, and based on real usage patterns and incident learnings
• Write clear, concise documentation and runbooks for enterprise security workflows
• Collaborate with partners across Engineering, IT, and Security to ensure proper implementation of security tools and policies
• Assist the Security Operations team during security investigations, acting as a technical subject matter expert within your domain
• Partner with engineering teams to triage and support remediation of vulnerabilities and misconfigurations
• Mentor engineers on the Security team to grow their domain knowledge, tool-specific skills, and communication abilities
• Champion, role model, and embed Samsara cultural principles (Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team)

Minimum requirements for the role:

• 5+ years of relevant experience in an Enterprise Security role with demonstrated impact
• Hands-on experience operating and maintaining endpoint security and visibility tools at enterprise scale (e.g. Crowdstrike, osquery, or similar)
• Exposure to at least one additional enterprise security tool stack beyond endpoint security, such as Secure Access Service Edge (SASE), zero trust systems, email security, Data Loss Prevention (DLP), or Identity and Access Management (IAM)
• An automation mindset with experience scripting and debugging code with Python (with or without AIassistance) and using SOAR platforms
• Strong familiarity with common security challenges and the ability to independently evaluate their severity and business impact
• Track record of delivering impactful work across multiple quarters and collaborating effectively across teams

An ideal candidate also has:

• Significant breadth across the endpoint security ecosystem, including designing layered controls with EDR tools, passive telemetry, integration with threat intelligence feeds, and operation in cloud and containerized environments.
• History of building out security programs using modern SaaS security platforms such as Crowdstrike, Mimecast Incydr, and Splunk
• Experience with infrastructure as code deployments using Terraform
• Experience with AI-driven automations
