About the role
About Us 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. Available Locations: Atlanta, GA, Austin, TX, Champaign, IL, Denver, CO, New York, NY, San Francisco, CA, Seattle, WA, Washington, DC About the Department Cloudflare's Engineering Team builds and runs the software that helps power millions of Internet properties. Product development covers both new features and functionality as well as scaling our existing software to meet the challenges of a massively growing customer base. The Content Delivery group helps make the Internet faster, safer, and more reliable by building and optimizing one of the world's largest CDNs. Role Summary The Cache team builds and operates the high-performance reverse proxy and caching data plane at Cloudflare's edge. Built on Pingora, Cloudflare's open-source Rust framework for fast, reliable network services, this software serves cached content, routes traffic across cache tiers, and connects Cloudflare to customer origins. Its performance, correctness, and resilience directly affect request latency, origin load, and availability across Cloudflare's global network. You will work primarily on the reverse proxy and the services that support it: backend routing and load balancing, cache storage and indexing, globally distributed purge, Tiered Cache routing, and production observability. These systems are also foundational building blocks for teams across Cloudflare, which use the proxy, caching, routing, and purge capabilities to power their own products. The team carries these capabilities through shared internal interfaces, distributed control planes, and customer-facing products including Cache Rules, Tiered Cache, Cache Reserve, Workers Cache API, and Always Online. Features ship end to end: you will help design, implement, test, roll out, and operate the systems you build. This is a good fit if you enjoy problems where latency, correctness, and reliability are hard requirements; where changes must be introduced safely across a global fleet; and where improvements can benefit a significant portion of Internet traffic. Role Responsibilities • Design, build, and operate the high-performance cache and proxy data plane that serves content at Cloudflare's edge and connects to customer origins • Contribute to Pingora and the productio
