About the Department

Cloudflare Research is involved with building the future of Cloudflare by tackling strategic projects that have a large impact on Cloudflare systems and the Internet at large. Team membersindependently drive greenfield projects, work closely with Cloudflare product and engineering teams on shared objectives, and build strong collaborations with both external organizations and other organizations within Cloudflare to achieve common goals.

Cloudflare Research embarks upon projects that help shape the future of the Internet at large, and the systems that drive it. We design, develop, and deploy these projects into Cloudflare systems to demonstrate their impact, and to share that knowledge with the wider standards and research communities -- often in collaboration with university or other industry labs. A sample of our recent high-profile works include Constellation AI, Encrypted Client Hello (ECH), Post Quantum Encryption, CAP, ZKP for browsers, and Addressing Agility. Our current research directions include applied cryptography, privacy, network protocols and architecture, measurement and performance evaluation, AI and ML for systems, systems for AI, and general distributed systems optimization.  We are open to researchers in all of these areas, and particularly solicit applications from researchers with a background in privacy.  Particular attention will be paid to candidates with experience in usability research. 

More information about Cloudflare's approach to research can be found here.

About the Role  

Researchers and engineers in the Research Team investigate new ideas, build new technologies, inform and execute measurement practices, and even dive into existing codebases to make meaningful changes in production environments. Prioritization and planning are key elements as the nature of the team’s research necessarily shifts between putting ideas into practice and onto paper, while ensuring rigorous evaluations of performance, correctness, or impact. The successful candidate will have a proven track record of success driving streams of investigation to completion.

General Requirements

• Proficiency in software development
• Must have a proven record of peer-reviewed research, standards, or equivalent in venues held by but not limited to ACM, USENIX, or IEEE.
• Solid foundation in computer science, with additional specialization in privacy and one or more Cloudflare-relevant areas such as usability, human-computer interaction, networking, distributed systems, storage, operating systems, or machine learning for systems.

• Excel at planning, working independently and multi-functionally, leading execution across teams to meet commitments, and deliver with predictability
• Demonstrate a track record of strong communication and technical influence. You’re as good as explaining “why” as you are “how.”
• Experience implementing tools, processes, internal instrumentation, methodologies, and resolving blockages
• Comfortable working on teams/projects with tight deadlines and short release cycles

Bonus Points

• Have completed a PhD or equivalent graduate research program in Computer Science, Mathematics, or related STEM field 
• Strong ties to and participation in standards bodies such as IETF, W3C, and others.
• Experience in differential privacy or multi-party computation
• Proficiency in one or more the following languages - Go, Rust, Typescript, C and/or Lua
• Experience designing and conducting user studies
• Familiarity with Kafka, Postgres, ClickHouse, Kubernetes, Prometheus, and tools such as Cloudflare’s Workers platform
• Demonstrated excellence in broad-audience technical communication (e.g. highly cited blogs, textbooks)
• Strong connections with the broader scientific community (arXiv presence, program committees, etc.)

To this end, you will:

• Collaborate closely with JavaScript web frameworks teams and tooling teams across the industry to ensure smooth development and production interoperability with our platform. Examples include Angular, Astro, Next, Nuxt, Qwik, Remix, Solid, SvelteKit, as well as Vite, Rollup, and many others.
• Surface requirements and collaborate with internal teams to build features to support ecosystem integrations.
• Contribute to open source projects across the web ecosystem in order to add features, fix issues, and improve integrations.
• Build and improve libraries, and tools that improve ecosystem compatibility, and the getting started experience, like C3 (create-cloudflare CLI) and next-on-pages CLI.
• Build demo applications, starter kits, and templates that enable developers to learn about our platform and get started using frameworks and libraries they are familiar with.
• Participate in JavaScript API design efforts evolving our platform, as well as JavaScript standards.
• Evaluate compatibility gaps between our workerd JavaScript runtime and Node.js, implement compatibility layers and polyfills to reduce developer friction when using existing libraries with our platform.
