Software Engineer, Agentic Discovery

<div class="content-intro"><h3>About Us</h3> <p>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.</p> <p>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.</p></div><h3><strong>Available Locations: Lisbon, or London (Hybrid)</strong></h3> <div class="container"> <div id="model-response-message-contentr_ccb59069932b9a6f" class="markdown markdown-main-panel md-content enable-luminous-fast-follows enable-updated-hr-color stronger tutor-markdown-rendering"> <h3>About the Department</h3> <p>Emerging Technologies &amp; Incubation (ETI) is where new and bold products are built and released within Cloudflare. Rather than being constrained by the structures which make Cloudflare a hugely successful business, we are able to leverage them to deliver entirely new tools and products to our customers. Cloudflare’s edge and network make it possible to solve problems at massive scale and efficiency which would be impossible for almost any other organization.</p> <h3>About the Team</h3> <p>We build the products that enable the next era of the Internet: making domains <strong>Readable</strong>, <strong>Discoverable</strong>, and <strong>Callable</strong> for autonomous AI agents.</p> <p>Here at Cloudflare, agentic discovery is a core part of our vision for the&nbsp;<a href="https://blog.cloudflare.com/the-agentic-internet/">Agentic Internet</a>. As AI agents change how humans and machines find, evaluate, and act on information, businesses need tools to control how they are represented and reached. We build capabilities that enable website owners to prepare their sites for agent interaction, test and observe how agents read their content, establish open interaction standards (like WebMCP and MCP), and create entirely new channels to reach agentic audiences.</p> <p>We are a cross functional group that communicates and collaborates regularly. We celebrate our achievements, support each other when we make mistakes, and hold each other and our work to a high standard.</p> <h3>About the Role</h3> <p>We are looking for a Software Engineer to join our Agentic Discovery team to build the core systems, protocols, and customer-facing tools powering agent-web interactions.</p> <p>In this role, you will design and ship scalable software across edge infrastructure, data pipelines, protocol layers, and developer tooling.
