What You’ll Do

The Traffic team's mission is to build software systems that improve the performance and reliability of our customers' traffic : from each end user to their destination.

  • The remit of the team is broad and we measure success by three key indicators : how successful end users are at reaching our network;
  • how successful our network is in reaching their destinations; and finally, how well we accelerate traffic between the two in order to provide the best experience.

    As a member of the Traffic team you will work on a variety of tools, systems, and even products to achieve these goals. You will contribute not only to internal systems that manage Cloudflare's network but also our customer-facing Argo Smart Routing product.

    You will participate in all stages of the software development lifecycle, from designing and documenting systems, to writing code and automated tests, to planning, managing, and monitoring production software deployments.

    You will work with a wide range of technologies and programming languages, including Go, Rust, Python, Linux networking, ClickHouse, Kafka, Salt, PostgreSQL, Grafana, Kubernetes, and more.

    Because you’ll be solving problems of massive scale and significance, and shaping the future of security and performance on the Internet, you are a growth-oriented individual who enjoys being outside of your comfort zone.

    You are comfortable in a fast-paced but sensible work environment.
