Data Center Design Engineer

At Cloudflare we are on a mission to help build a better Internet. Today the company runs one of the worlds 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 Magazines Top Company Cultures list and ranked among the Worlds Most Innovative Companies by Fast Company.

At Cloudflare were not looking for people who wait for a polished roadmap; were looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a normalized problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration leveraging AI to ship faster today to make it better tomorrow while ensuring that every improvement no matter how small is shared across the team to lift everyone up. If youre the type of person who values curiosity over bureaucracy and that AI is a partner in solving tough problems to keep the Internet moving forward youll fit right in.

Were not just a highly ambitious large-scale technology company. Were 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 weve equipped more than 2400 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 Cloudflares 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 weve 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. Heres the deal - we dont 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.
