Software Engineer, CDN Configuration Group

At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.

Cloudflare's Engineering team is responsible for the software platform that serves tens of millions of HTTP requests per second on average. We also build and run the tools that empower our colleagues to rapidly deliver products to market, as well as monitor and deploy software updates across the globe to over 200+ data centers. You'll experience the full breadth of technologies needed to run one of the world's largest networks serving the world's largest customers such as Shopify and VISA.

The CDN Configuration team oversees the end-to-end configuration ecosystem across our edge platform. Our core mission is delivering a coherent, safe, highly performant, and resilient experience that empowers customers to modify their traffic routing with absolute confidence. We enable users to build and tailor their own virtual network by rapidly generating settings and deploying updates globally without friction. While core teams engineer individual edge components, our group architecturally unifies these capabilities, enabling customers to seamlessly orchestrate their entire pipeline.

Collaborating with skilled software professionals, you will deliver robust mechanisms that grant users total governance and safety across their network settings. Your focus involves architecting services that let users seamlessly prototype, execute, evaluate, and discard tailored traffic rules, ensuring optimal alignment with their operational requirements. This scope extends far beyond a solitary codebase; you will directly interface with distributed edge platforms, partnering with cross-functional groups to streamline and fortify our global infrastructure.

In this role, you will stand at the intersection of core application deployment and infrastructure operations, driving technical alignment alongside engineering peers across the organization.
