Careers at Cloudflare

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 production services built on it, improving asynchronous I/O, connection handling, memory and disk efficiency, and tail latency Improve cache correctness and performance through object placement, retention, admission and eviction policies, range-request handling, and resilience to corrupt or incomplete data Build globally distributed purge and Tiered Cache systems that invalidate content quickly, select efficient cache paths, improve hit rates, and reduce origin load Deliver shared platform capabilities and customer-facing APIs and rules for cache keys, TTLs, response handling, purge behavior, and programmatic access from Workers Own features end to end: write technical designs, implement services and libraries, add automated tests and observability, drive staged rollouts, and operate the resulting systems in production Participate in the team's on-call rotation, lead incident response and post-mortems, and continually improve reliability, capacity, and operational tooling Reason carefully about failure modes and blast radius, using traffic cohorts, measurable guardrails, and rollback mechanisms to introduce high-impact changes safely Partner with product and engineering teams across Cloudflare that depend on or extend the cache and proxy platform Raise the engineering bar through code review, mentorship, clear written communication, and improvements to team standards and tooling Role Requirements (Must-Have Skills) Minimum 4 years of professional experience designing, building, and operating production software systems Strong proficiency in at least one systems or backend language such as Rust, Go, C, or C++, with a willingness to work in Rust Strong understanding of HTTP semantics and transport protocols such as TCP, TLS, and QUIC Experience designing and implementing secure, resilient, high-performance distributed systems Experience with Linux systems, networking, concurrency, and performance analysis Track record of production ownership, including monitoring, debugging, on-call, incident response, and ongoing reliability improvements Experience using metrics, logs, traces, profiling, and experiments to understand production behavior and validate improvements Strong written and verbal communication skills, including the ability to write clear technical designs and lead projects across team boundaries Willingness to use AI-assisted engineering tools to accelerate development and investigation while remaining accountable for correctness, security, and design quality Nice-to-Have Skills Professional experience with Rust or high-performance asynchronous systems Experience with caches, HTTP proxies, CDNs, distributed storage, or latency-sensitive data-plane services Experience analyzing memory use, disk I/O, resource contention, and tail latency in production systems Experience building APIs or distributed control planes using event streaming, relational databases, or analytical data systems Familiarity with Kubernetes, Kafka, PostgreSQL, ClickHouse, or similar infrastructure Experience contributing to open-source software or leading multi-team engineering programs Compensation Compensation may be adjusted depending on work location and level.

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 hand that work to them. Resolve cross-team dependencies with the Workers, Developer Platform, Security and Billing teams, and bring contentious technical decisions to closure quickly and calmly. Own the commercial mechanics of a billed service, including the unglamorous parts: usage metering, quotas, plan limits, abuse protection and pricing input. Represent Browser Run externally through launch blog posts, developer documentation, conference talks and direct customer conversations. About you We want you to love it here. This role is a great fit for you if: You have run an engineering team that shipped, and you can point at what it shipped. You give your technical legos away. Your measure of success is the team’s output and the growth of the people on it, not your own commit history. You are comfortable with ambiguity. Incubation means the requirements move, and you can change direction without drama. You are direct. You give feedback early, disagree openly, and admit when you were wrong. You write well. You believe a clear design document, roadmap or incident report is as much of a deliverable as the code. You care about operational quality and treat a noisy alert as a bug, not as background noise. You find browsers genuinely interesting as an engineering problem — how Chrome behaves under load, why automation breaks, and what an AI agent actually needs from a browser it does not own. You want to join a team that upholds a culture of support, open and honest communication, and collaborative problem-solving. Examples of Desirable Skills, Knowledge, and Experience 2+ years managing engineering teams, on top of a solid track record as a hands-on engineer. Experience owning a production service end to end, including on-call rotation, capacity planning and incident review. Demonstrated experience growing engineers — promotions you supported, and ideally a team lead or first-line manager you developed. Hands-on familiarity with browser automation — Chrome DevTools Protocol, Puppeteer or Playwright — or with the browser internals underneath them. Strong technical grounding in distributed systems, web platform fundamentals (HTTP, JavaScript execution models, rendering) or cloud infrastructure — enough to hold a credible design review. A track record of partnering with Product Management to set and defend a roadmap, including saying no. Excellent written communication for internal and public-facing technical content. Experience hiring: writing job descriptions, running interview loops, calibrating a panel and closing candidates. Bonus Points Experience running headless browser infrastructure at scale — browser fleet management, sandboxing and resource isolation. Experience shipping AI or agent-facing platform primitives, such as MCP servers, tool-calling surfaces or agent orchestration. Familiarity with the Cloudflare Workers development platform: Workers, Durable Objects, Workflows, R2, D1. Experience taking an internal tool to a billed external product, including usage metering and pricing. Experience managing a distributed team across time zones. Open source maintainership, or a public body of technical writing.

Rather than being constrained by the structures which make Cloudflare a massively 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. The Workers Runtime team delivers features and improvements to our Runtime which actually executes customer code at the edge. We care deeply about increasing performance, improving JS API surface area and compiled language support through WebAssembly, and optimizing to meet the next 10x increase in scale. The Runtime is a hostile environment - system resources such as memory, cpu, I/O, etc need to be managed extremely carefully and security must be foundational in everything we do. Our work is deeply systems-oriented. We build and maintain the C++ and Rust codebase that embeds the JavaScript engine, manages isolate lifecycles, enforces resource limits (CPU, memory, I/O), and orchestrates how customer scripts are loaded, cached, and executed. We operate in a hostile multi-tenant environment where security must be foundational — from side-channel attack mitigations to isolate sandboxing — and performance is measured in microseconds. Responsibilities You will lead the Workers Runtime - Edge team, owning the runtime service in production across Cloudflare’s fleet and driving the architectural evolution of the platform. Lead a team of senior systems engineers working in C++ and Rust on one of Cloudflare’s most performance-critical and security-sensitive services. Drive major infrastructure initiatives, including migrating legacy systems, redesigning core abstractions, and laying the groundwork for next-generation runtime architecture. Own reliability and release safety for a service handling tens of millions of requests per second. Improve release processes, invest in health monitoring and automated rollback, and help the team ship changes confidently at scale. Make prioritisation calls between customer-unblocking feature work and foundational investment in security, reliability, and developer velocity. Partner closely with adjacent teams across the Developer Platform to ensure the runtime supports the broader product roadmap, including compute, storage, networking, and observability. Hire, grow, and develop strong systems engineers; set clear expectations, provide technical mentorship, and create an environment where people do their best work. Desirable Skills, Knowledge & Experience Experience leading a team. Comfortable leading and hiring a team that builds low-level distributed systems.

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.
