About the Role
We are looking for talented Systems Reliability Engineers to build and operate our Edge platform running in more than 320 cities in over 120 countries. Our SREs come from diverse technical backgrounds and have built up their knowledge working in different environments, but common factors across all of our reliability-focused engineers include a passion for automation, scalability, and operational excellence.

SREs focus on the immediate state and functionality of the Cloudflare platform around the world, leveraging an array of monitoring, alerting and diagnostics tools while developing and enhancing the Cloudflare platform and its capabilities. We own a wide portfolio of applications and services, running a tight feedback loop of developer and operator patterns.
