Engineering Manager, Browser Run

Role details

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: Lisbon About the Department Emerging Technologies & 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. About the Team We build the tooling and platform capabilities that power the next generation of AI agents on the Cloudflare Developer Platform. Our goal is to make it easier for agents to interact with the web, and to be observed and controlled while they do it — without giving up performance, scalability or security. Browser Run is the centre of that work, and it is the product this role owns. It runs full browser sessions on Cloudflare’s global network and lets developers drive them with code or with an agent: a Chrome DevTools Protocol endpoint that any Puppeteer, Playwright or CDP client can connect to from anywhere, Workers bindings, and a REST API for the common jobs — screenshots, PDFs, Markdown extraction, scraping and crawling. On top of that sit session recording and replay, live debugging, and a path for a human to step in when an agent gets stuck. It is used by external developers building agents, crawlers and scrapers, and by other Cloudflare teams who need a browser they can trust. It is also a billed product on a steep growth curve, which makes capacity, cold-start latency, concurrency limits and abuse protection product problems rather than merely operational ones. The team’s wider portfolio includes an agent-first browser built on Workers rather than containers, a managed CI platform for the agent development lifecycle, visual regression testing delivered as a service, a pre-rendering service, URL Scanner, and CDNJS. Browser Run is the focus of this role today; there is scope for more of that portfolio to come into it as the role and the team grow. Browser Run went from an internal rendering tool to a public, billed product, and the surface has not stopped moving — the CDP endpoint, MCP client support, session replay and the REST API all landed inside a year. That pace is the point, and it is the thing this role has to make sustainable. We are a tight-knit team that communicates and collaborates regularly. We celebrate our achievements, support each other when we make mistakes, and hold each other and our work to the highest standard. About the Role This is a hands-on engineering management role. You will own Browser Run engineering end to end — the people, the roadmap, the reliability, and the story we tell customers about it. You will report to the Senior Engineering Manager for AI Agents Tooling & Platform and partner closely with Product Management, Developer Relations, and platform teams across Cloudflare. Browser Run is the primary focus. The team owns other products, and there is scope for some of them to move into your remit as the role and the team grow, but we are hiring someone to make Browser Run excellent first. You will not be writing most of the code. You will be expected to understand it well enough to review a design document, challenge an architecture, and know when an estimate is wrong. What you’ll do Manage, coach and grow the team of systems engineers behind Browser Run — 1:1s, career development, performance conversations, and hiring. Own the Browser Run roadmap and delivery, and give the team and the wider organisation clear visibility into what is being worked on, in what order, and what we are deliberately not doing. Partner with Product Management to set direction: shape the roadmap, pressure-test scope, and make the trade-off calls that keep an incubation product shipping. Own Browser Run’s operational health — browser fleet capacity, session reliability, cold-start latency, concurrency limits, on-call rotations, alert quality and incident follow-through. External developers and other Cloudflare teams depend on this service. Keep the automation surface honest: Puppeteer and Playwright compatibility, CDP behaviour that matches what developers expect from a local Chrome, and a credible story for Chrome version upgrades. Develop leaders. Identify and grow the engineers who will run day-to-day delivery for an area of the product, and
