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.
About the Department
Cloudflare's Research Team pursues strategic projects that have a large impact on Cloudflare systems and the Internet at large. Our focus is on solving difficult problems to connect and protect users, applications, and data, while helping to make the Internet more resilient, efficient, and transparent.
In our quest to help make a better Internet, we frequently find ourselves exploring open problems at the boundaries of knowledge in scalable computing, with a focus on security and privacy, using techniques including AI/ML and performance analysis.
We make cutting-edge research contributions in-house, as well as in collaboration with academia, Internet standards organizations like the IETF, and more!
Our team includes experts in many disciplines, including applied cryptography, privacy, network architectures and protocols, measurement, distributed systems, storage optimization, machine learning for systems, and more.
What You'll Do
Cloudflare's Research Team solves difficult problems in security, privacy, and systems at scale. This involves engineering, data analysis, open source software development, protocol design, implementation of primitives, with lots of measurement alongside.
Successful candidates will be matched to suitable projects in on-going research directions. We also welcome novel proposals and ideas that can help to inform or build a better Internet (in the form of a max 200 word proposal).
The Internet is evolving in ways that challenge convention, and many existing assumptions no longer hold. Interns and internship projects are designed to help maintain the integrity of the Internet, its systems, and its applications.
Some of the fundamental areas we're investigating focus on include advanced cryptography, hardware isolation, balancing user privacy against notions of identity, network and internetwork observability in a seemingly fragmented world, even applications of formal methods at scale , and this is just a small view into our work!
General Research Intern Requirements
- Evidence of tackling hard or open-ended problems
- Proven track record of peer-reviewed research, open-source software contributions, or standards development, that is commensurate with level of training
- Experience clearly communicating research ideas through papers, pre-prints, standards documents, blogs, or similar media
- Ability to work in a systems-level programming language (e.g. Rust, C, Go)
- Passion for debugging and ensuring system reliability
- Familiarity with continuous integration workflows and source control systems (e.g., Gitlab, Github)
- 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, ideally in systems or network optimization + Authentication protocols, applied cryptography, PKI and SSL/TLS + Operating or distributed systems analysis or development + Measurement for network and computer systems + Proficiency in a scripting language, such as Python
Internship Availability and Expectations
- Ability to commit to a 12 week summer internship
- In office 3-4 days a week in Lisbon, Portugal
What Makes Cloudflare Special?
We're not just a highly ambitious, large-scale technology company. We're a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.
Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare's enterprise customers--at no cost.
Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.
1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released.
Here's the deal - we don't store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
