The Network Platform Organization (formerly Meraki) builds and operates Cisco’s cloud-managed platform powering millions of devices globally. Within NPO, the Network Platform Security Organization (NPSO) is responsible for protecting the platform, infrastructure, and customers through mature engineering and operation of security controls.
The Security Engineering team within NPSO engineers and operates enterprise-grade security platforms across a diverse, large-scale, hybrid cloud environment.
This role is ideal for a senior-level endpoint security engineer who wants to own the lifecycle, reliability, and operational maturity of SentinelOne as a critical EDR platform while influencing the security design of platforms used by tens of millions of customers worldwide.
Your Impact
Own SentinelOne as a production EDR control, improving endpoint coverage, policy lifecycle management, agent reliability, alert quality, upgrades, troubleshooting, and incident support.
Engineer endpoint protection for Linux, cloud-hosted, Kubernetes/EKS, and container workloads while balancing security, performance, reliability, and operational maintainability.
Deliver repeatable endpoint controls through infrastructure-as-code, configuration management, Git-based CI/CD, Ansible, Terraform, ArgoCD, and automated validation workflows.
Build scripts, runbooks, and guardrails that make endpoint security operations scalable and support vendor evaluations and design reviews for endpoint, workload, and cloud security platforms.
Integrate EDR telemetry with Splunk, Grafana, Prometheus, and related observability platforms; track health, coverage, detection, and response metrics; and close logging or alerting gaps.
Mentor engineers and partner with SRE, infrastructure, compliance, and security teams to keep endpoint security aligned with production needs and regulatory requirements.
