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. We support our services in a “follow the sun” model with offices in East Asia, Europe and North America. This is a superb opportunity to join a high-performing team and scale our high-growth network as Cloudflare’s business grows. We live at the boundary between systems, network, and software, and love improving the glue that holds them together. Working with us, you will build tools to constantly improve service availability, performance, and operational velocity. You will nurture a passion for an “automate everything” approach that makes systems failure resistant and ready to scale. 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 range of applications and services, running a tight feedback loop of developer and operator patterns. The ideal SRE candidate has a passionate curiosity about how the Internet fundamentally works and has a strong knowledge of networking, Linux and TLS along with coding ability in Go or Python. This role may require flexibility to be on-call outside of standard working hours to address technical issues as needed.
