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 world’s largest networks that powers approximately 25 million 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. 

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

About The Team

We build security products for our customers and work mostly in Go and Rust. One of our challenges is developing and deploying machine learning models that can withstand a huge scale of 50 million peak requests per second. Our flagship Machine Learning products are WAF Attack Score and Page Shield ML. 

Our Software Engineers with a focus on Machine Learning work with Data Scientists, Product Managers and Security Analysts to develop and deploy ML algorithms which aim to protect customers against application and network vulnerabilities (at L3 and L7), by analyzing data passing through our network. We also build systems to help customers understand this data themselves.
