About the Department

Cloudflare’s Technology team is working on building the future of Cloudflare by tackling strategic projects that have a large impact on the way Cloudflare systems, and the Internet at large, work. Engineers in the Technology team are expected to research new ideas and technologies, dive into existing codebases to make meaningful changes, work independently on greenfield projects, and collaborate closely with the engineering organization to achieve common goals.

The Cryptography team is a sub-team of the Technology team focused on solving difficult problems in security, performance, and privacy at scale using cryptographic tools. This involves systems engineering, open source software development, protocol design, the implementation of cryptographic primitives, contributions to cutting-edge research in collaboration with academia, participation in Internet standards organizations like the IETF, and more.

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: We equip politically and artistically important organizations and journalists 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.

Project Athenian: We created 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.

Path Forward Partnership: Since 2016, we have partnered with Path Forward, a nonprofit organization, to create 16-week positions for mid-career professionals who want to get back to the workplace after taking time off to care for a child, parent, or loved one.

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 policy and ensure that no user data is sold to advertisers or used to target consumers.

Sound like something you’d like to be a part of? We’d love to hear from you!

Cloudflare hires the best people based on an evaluation of their abilities and effectiveness. We don't discriminate against employees on the basis of any other personal characteristic or any classification protected by federal, state or local law.
