Software Engineer - Kubernetes

Many of Cloudflare’s critical internal services run on Kubernetes. These services include those responsible for Cloudflare’s control plane and APIs, data analytics and other internal tools used to manage our global network. These Kubernetes platforms are purpose-built from the ground up and run on bare metal Linux in different regions around the world. The scale we work at involves tens of thousands of containers and terabits per second of network traffic. The team takes pride in knowing this platform helps run parts of the global Internet.

As an engineer on the Kubernetes platform team, you'll be building the tools to help engineers deploy and operate the services that make Cloudflare work.

• A firm grasp of IP networking including routing and iptables
• Excellent debugging skills in a Linux environment
• Source control experience including branching, merging and rebasing
