About Us

At Cloudflare, we have our eyes set on an ambitious goal: to help build a better Internet. Today the company runs one of the worlds largest networks that powers more than 10 trillion requests per month. Cloudflare protects & accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare have all web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance & a decrease in spam & other attacks. Cloudflare was recognized by the World Economic Forum as a Technology Pioneer & named to Entrepreneur Magazines Top Company Cultures list.

We realize people do not fit into neat boxes. We are looking for curious & empathetic individuals who are committed to developing themselves & learning new skills, & we are ready to help you do that. We cannot complete our mission without building a diverse & inclusive team. We hire the best people based on an evaluation of their potential & support them throughout their time at Cloudflare.

About the department

Cloudflares Engineering Team builds & runs the software that handles requests on the Internet today. We also build & run the internal tools that builds & runs our software. The Engineering Team is split into two groups: one handles product development & the other handles operations. Product development covers both new features & functionality & scaling our existing software to meet the challenges of a massively growing customer base. The operations team handles one of the worlds largest networks with data centers in 102 cities worldwide.

What Makes Cloudflare Special?

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 & open Internet.

Project Galileo: We equip politically & artistically important organizations & journalists with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflares enterprise customers--at no cost.

Project Athenian: We created Athenian Project to ensure that state & local governments have the highest level of protection & reliability for free, so that their constituents have access to election information & 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. We released to help fix the foundation of the Internet by building a faster, more secure & 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 policy & ensure that no user data is sold to advertisers or used to target consumers.
