About the role

Systems Engineer to build and operate production services for Cloudflare's User and Entity Behavior Analytics (UEBA) pipeline, focusing on behavioral detections, risk scoring, and customer-facing investigations within Cloudflare One.

Responsibilities

  • Build behavioral detections. Turn product requirements and 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.

Qualifications

  • 3+ years of professional experience building, testing, and operating backend or distributed systems in production.
  • Strong proficiency in at least one systems programming language (e.g., Go, Rust, C/C++) with a track record of writing clean, maintainable code.
  • 3+ years of practical experience with databases and data-intensive services—for example, PostgreSQL, ClickHouse, or comparable relational or analytical stores.
  • Experience reasoning about event-driven systems: message delivery, duplicate or late events, state, failure recovery, and safe changes to live consumers or APIs.
  • Clear written and verbal communication, and an ability to work through technical decisions with product and engineering partners.
  • Experience using metrics, logs, traces, profiling, and experiments to understand production behavior and validate improvements.
  • Bring strong opinions, clear judgment, and a willingness to revise your view when data, users, or production reality prove otherwise.
