About the Role This is a hands-on software engineering role on the Cloudflare One Appliance team. You will shape and build the Linux-based edge runtime and distributed control plane that connect customer sites to Cloudflare. As a Senior Systems Engineer, you will work across low-level systems, distributed services, and API design while providing technical leadership for major initiatives. Our architecture follows a “light branch, heavy cloud” philosophy: policy and intelligence belong in Cloudflare’s network unless locality is required for correctness, survivability, performance, or user experience. You will use strong technical judgment to decide what belongs to the appliance and what belongs in the Cloudflare's network, building systems that are secure, observable, resilient to partial failures, and safe to operate across a large fleet carrying customer-critical traffic. Responsibilities Build systems end to end: Design and implement capabilities spanning the cloud control plane, Linux appliance runtime, telemetry pipeline, and physical, virtual, and cloud deployment environments. Build a Linux-based networking platform: Develop and harden the appliance dataplane. Build secure, reliable networking capabilities using technologies such as IPsec, MASQUE, eBPF, and Linux kernel networking primitives while keeping the system small, predictable, and secure. Engineer reliable fleet control: Build distributed control-plane and state-management systems that safely deliver configuration and commands, tolerate intermittent connectivity and partial failures, converge to known-good state, and support zero-touch operation across large device fleets. Secure the device lifecycle: Improve hardware-backed identity, attestation, secure boot, immutable operating-system images, credential rotation, and staged over-the-air upgrades with safe rollback and recovery. Make operability a product feature: Design telemetry, diagnostics, synthetic tests, support bundles, and remote operations that help customers and support teams understand the system without treating the appliance as a black box. Drive customer-centered product decisions: Work with customers, Product, Support, and Solutions Engineering to understand customer requirements and turn them into pragmatic technical direction. Bring clear opinions, and revise them when customer feedback or production evidence points to a better answer. Own production outcomes: Prototype quickly, ship in safe increments, and own rollout, monitoring, incident follow-up, and long-term maintainability. Lead across teams: Set architectural direction for major initiatives, write clear technical proposals, conduct rigorous reviews, and mentor other engineers. Build executable plans with Cloudflare WAN, Gateway, DEX, the Cloudflare One Client, and platform and security teams. Role Requirements Must-Have Skills 8+ years of professional software engineering experience building complex production systems. Strong software engineering skills in Rust, C/C++, Go, or a comparable system programming language, with the ability to work across the stack, including TypeScript. Strong understanding of Linux networking internals, with experience building against the kernel networking stack using eBPF/XDP, netlink, and network namespaces. Experience designing and implementing distributed control planes, desired-state reconciliation, remote configuration, or similar systems that manage large, intermittently connected fleets. Experience designing secure systems, including threat modeling, least privilege, credential handling, and software supply-chain integrity. A track record of owning ambiguous initiatives from discovery through production, including architecture, implementation, staged deployment, incident response, and failure analysis. Technical leadership and communication skills that let you influence decisions, explain system trade-offs to different audiences, and bring stakeholders toward a clear outcome. Product judgment grounded in customer evidence, usability, and operational simplicity. Practical experience using AI-assisted engineering tools, coding agents, harnesses, or automation responsibly to improve engineering quality and throughput. Nice-to-Have Skills Experience building networking products or systems, such as SD-WAN, SASE, SDN platforms, or network operating systems. Experience building custom or embedded Linux distributions with immutable, image-based update systems such as RAUC, bootc, or OSTree. Experience with UEFI Secure Boot, TPMs, hardware-backed identity, or remote attestation. Experience building networking features such as high-availability failover, dynamic routing, multi-WAN, traffic steering or shaping, application identification, or local policy enforcement. Experience building automated fleet tests, hardware-in-the-loop or network-in-the-loop test environments, safe staged rollouts, and remote diagnostic tooling.

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.

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: Austin, Lisbon, or London (Hybrid) About the Role 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 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. Strong planning skills, with experience creating teams and overseeing execution to meet commitments predictably. Comfortable building developer-loved APIs that scale. Track record of leading a team through hiring, onboarding, and professional development. Ability to explain both the “why” and the “how.” Experience implementing tools, process improvements, internal instrumentation, methodologies, and resolving blockages. At least 4 years of recent professional experience with C++ or Rust. Solid understanding of computer science fundamentals, including data structures, algorithms, and object-oriented or functional design. Deep understanding of the web and technologies such as web browsers, HTTP, JavaScript, and WebAssembly. Strong understanding of Linux systems programming, process models, and networking. Bonus Points Experience building high-performance distributed systems. Experience working with cloud platforms, especially server-less platforms. Experience with the internals of JS engines such as V8, SpiderMonkey, or JavaScriptCore. Experience with standalone WebAssembly runtimes such as Wasmtime, Wasmer, Lucet, etc. Deep Linux/UNIX systems, kernel, or networking knowledge. Contributions to large open source projects. Experience working in low-latency real-time environments such as game streaming, game engine architecture, high-frequency trading, or payment systems. Experience debugging, optimizing, and identifying failure modes in a large-scale Linux-based distributed system. Compensation Compensation may be adjusted depending on work location. ● For New York City, New Jersey, Washington, Washington DC, and California (excluding Bay Area) based hires: Estimated annual salary of $220,000 - $303,000 ● For Portugal based hires: Estimated annual salary is between €89,000 - €122,000.
