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.

Available Locations: Lisbon, Portugal 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 products at the intersection of AI, search and retrieval, data insights, and product engineering. As AI agents change how people discover and interact with the Internet, new problems are emerging around how content is found, understood, retrieved, and kept current. Cloudflare is uniquely positioned to help website owners make their content discoverable and to help agents find relevant, trustworthy information across our network. Building these capabilities requires solving problems across distributed systems, crawling, content ingestion, indexing, retrieval quality, developer experience, and reliable product delivery. Cloudflare also has a unique perspective on how the Internet is changing. Our global network observes signals that can help us understand trends, identify when content changes, and measure the pulse of the Internet. Used responsibly, these signals could improve existing products, help customers and AI companies find fresher and more relevant information, and create entirely new capabilities and products. The opportunity is broad and still evolving. We need to deliver excellent products today while continuing to identify the problems Cloudflare is uniquely positioned to solve next. We are a tight-knit 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. About the role We are looking for an Engineering Manager to lead engineering across some of our AI and Internet Data Insights portfolio. You will be responsible for the people, execution, and engineering quality behind products that help customers make their content discoverable and turn complex Internet signals into useful experiences. You will partner closely with Product Management and engineering teams across Cloudflare to deliver current priorities and shape future opportunities. This is a management role for someone who is deeply technically credible. You will not be expected to write most of the code, but you should be able to understand the systems your engineers operate, challenge architectural decisions, ask the right questions when something is going wrong, and step into a technical problem when the situation calls for it. At the same time, we are looking for a manager, not a tech lead with direct reports. Your success will be measured by the quality and output of the team you build, the engineers you develop, and the systems and products they deliver. This role may require flexibility to be on-call outside of standard working hours to address technical issues as needed. What you'll do Manage, coach, and grow engineers working across AI-powered search, Internet data insights, and customer-facing products. Own execution by establishing clear priorities, creating predictable delivery, and giving engineers the context and autonomy to own meaningful areas of the product. Lead the development of search and retrieval capabilities that help people and AI agents find relevant, trustworthy, and current content. Partner closely with Product Management to understand customer problems, shape the roadmap, and turn broad opportunities into clear engineering outcomes. Help identify how signals from Cloudflare's global network can produce useful and trustworthy insights for customers, partners, and other Cloudflare products. Explore where Cloudflare's unique view of Internet activity can improve content discovery, enable new product experiences, or support entirely new products. Balance near-term product delivery with thoughtful technical investments that allow promising ideas to grow. Own the operational health of the systems in your area, including observability, incident response, data and search quality, and long-term reliability. Develop technical leaders and create space for engineers to lead architecture and implementation. Responsibilities We want you to love it here. This role is a great fit for you if: You have led and developed high-performing engineering team(s) and can point to what that team shipped and how the people on it grew. You are technically credible with experienced engineers. You can review a design, understand the trade-offs in a distributed system or data platform, and recognize when a technical problem needs deeper investigation. You are comfortable managing a team working across several related technical areas and can create clarity without requiring every problem to fit neatly into a single box. You care deeply about reliability and quality, particularly when the output of a system is data that people use to understand the Internet. You have strong product judgment and enjoy working with Product Management to decide what is worth building, what needs improvement and what should not be built at all. You are comfortable with ambiguity and with finding structure in areas where the opportunity is clearer than the roadmap. You communicate clearly, give direct feedback, and can explain complex technical decisions to both engineers and non-engineers. Examples of Desirable Skills, Knowledge, and Experience Strong technical grounding in distributed systems, search systems, data-intensive systems, Internet infrastructure, or adjacent areas. Experience building or operating products involving crawling, content ingestion, indexing, retrieval, analytics, or large-scale data processing. Experience operating systems where correctness, reliability, and quality matter as much as feature delivery. A track record of hiring, developing, and retaining strong engineers. Experience partnering closely with Product Management to shape and execute a roadmap. Experience taking products or major capabilities from an ambiguous opportunity to a clear customer outcome. Strong written and verbal communication. Bonus Points Familiarity with Retrieval-Augmented Generation (RAG), which combines information retrieval with generative AI to produce answers grounded in selected source material. Experience building products for AI developers, AI agents, publishers, or content-heavy websites. Experience working with large-scale telemetry or Internet-scale datasets. Experience turning complex underlying systems or data into useful products for a broad audience. Familiarity with Cloudflare Radar, Internet measurement research, or the broader ecosystem of tools used to understand Internet performance, availability and security.
