Cloudflare One brings together secure access, network connectivity, and data protection. Our products generate massive amounts of signals about how people and agents access applications, use the network, and handle data—but a security practitioner needs more than isolated events.

What you'll do

• Build behavioral detections . Turn product requirements and available: telemetry into production-ready detections across signals such as Access, Gateway, DNS, device posture, and data protection. Define the data dependencies, evaluation approach, and how you will assess signal quality before release.

• Make risk understandable . Help connect detection output to event history,: logs, and customer-facing investigations so practitioners can see what triggered a finding and how a user’s risk changed.

• Design & Scale Infrastructure: Architect, deploy, and maintain robust distributed systems, focusing on high availability, low latency, and horizontal scalability.

• Collaborate across teams . Collaborate with Product and engineers in Access,: Gateway, Analytics and Reporting, Logs, and other data-producing or data-consuming teams to agree on event contracts and deliver end-to-end functionality.

• Ensure Reliability . Participate in architecture reviews, capacity planning,: and proactive system health monitoring to guarantee maximum uptime and resilience.
