Applications are closed

  • Internship
    Full-time
    Off-cycle Internship
  • Research & Development

Requirements

  • Interest in solving open-ended problems.
  • Proven track record of peer-reviewed research, open-source software contributions, or standards development
  • Some level of research maturity is expected, but students at every level are welcome to apply
  • Evidence of ability to work in multiple languages -- Go, Rust and Javascript are particularly desirable.
  • Experience (and love) for debugging to ensure the system works in all cases.
  • Experience with a continuous integration workflow, and use of source control (we use git)
  • Strong systems level programming skills.
  • Willing and eager to share knowledge, with the skills to do so.
  • Additional Requirements
  • Knowledge or experience with at least one of the following:
  • Computer networking protocols (TCP/IP, DNS, BGP, QUIC, etc.) and related algorithms
  • Machine learning analysis for systems or network optimization
  • Authentication protocols, applied cryptography, PKI and SSL/TLS
  • Operating or distributed systems analysis or development
  • Applied cryptography and cryptographic protocols
  • Measurement for network and computer systems
  • Bonus Points:
  • Proven track record of independently driving projects in a fast-paced environment
  • Experience with high throughput/low latency real-time systems and/or content delivery networks

Responsibilities

  • Research Program Areas
  • Cloudflare Research has six current program areas. Candidates whose interest or expertise lie outside one of these areas are also encouraged to apply, particularly if they have a particular, specific interest in an aspect of Cloudflare’s technical stack or operations.
  • Applied AI/ML :
  • Machine learning and statistical automation is a valuable toolkit for research across Cloudflare’s products and services. The AI/ML research team seeks to answers cutting edge questions at the intersection of machine learning and scalable system design to answer questions about fraud, predictive optimization, and distributed learning.
  • Internet Infrastructure and Governance:
  • Cloudflare Research is dedicated to the health of the broader Internet, including significant work with standards bodies (IETF, W3C, NIST, e.g.) and open implementations. This program explores ways to improve the underlying infrastructure of the Internet and promote its fair and equitable governance. This umbrella also includes decentralized web technologies and protocols such as IPFS and Web3. Example project areas include Internet routing security and resilience (e.g., RPKI, BGP), DNS and domain name security improvements, and addressing the global digital divide.
  • Measurement and Performance Optimization:
  • A key driver of research questions and outcomes is observability into system behavior. This program area focuses on researching and developing novel techniques to measure and improve the performance and reliability of websites, applications, and services hosted on Cloudflare infrastructure. Example project areas include cache and CDN optimization, time series and ML/AI based performance analysis, edge computing and serverless applications, and network congestion control and latency reduction techniques.
  • Privacy and Data Protection:
  • This program is about reducing or eliminating personal data at all layers of the stack, as well as metadata on the broader Internet, to ensure the protection of user data and maintain compliance with global data protection regulations. This work includes efforts to upgrade protocols to enable better data privacy (e.g. hostnames -- via SNI, IP addresses, or fingerprintable data) as well as cryptographic techniques such as secret splitting to limit the potential for compromising private data. Example projects include cryptographic Attestation of Personhood, privacy-preserving analytics, website fingerprinting protection, and connection coalescing.
  • Security and Resilience:
  • ​​The Internet is continually evolving, and dangers to the Internet evolve with it. This program is dedicated to researching and developing innovative solutions to protect Cloudflare's infrastructure and its customers, as well as the Internet at large, from various cyber threats. Efforts in this area frequently include close collaboration with teams across Cloudflare, such as a recent push to deploy post-quantum security throughout Cloudflare’s internal network. Example project areas include DDoS attack mitigation and prevention, bot and automated threat detection, secure DNS, and zero-trust architectures and access control.
  • Systems and Formal Methods:
  • Formal methods are a powerful toolkit for answering the types of questions around privacy, security, and correctness that are core to Cloudflare’s operations. The Systems and Formal Methods group is the home for questions about system architecture and correctness that fall outside the realm of pure networking or privacy research. Sample projects include kernel-level cryptography implementations, cache design and observability, and logging and analysis.
