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.
At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re 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 you’re 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, you’ll fit right in.
Available Locations: Lisbon, Portugal
Cloudflare helps build the future of the Internet. The Emerging Technology and Incubation (ETI) team invents, launches, and brings to market the technologies required to reach that goal. ETI ships software that changes the Internet. The world's fastest DNS resolver, 1.1.1.1, Cloudflare WARP, Email Routing, Radar, Cloudflare Workers, D1, R2, and Workers AI are examples of our launches.
The team members in ETI make this possible. The group consists of engineers, product managers, developer advocates and researchers who share a common passion for helping build a better Internet. The ETI organization encourages individual team members to be ambitious and bold in how we find and solve problems. We move quickly and shape our products based on customer usage and feedback, while leveraging the massive scale and reliability of our global network.
ETI also helps drive our Innovation Weeks at Cloudflare and contributes with new products, features, and visions for helping build a better Internet. Doing that requires all of ETI to execute on releases that customers will use today, tell our story as part of Cloudflare’s larger mission, and to build products that allow Cloudflare’s customers to realize that 1+1 can equal 3 when using all of these features together.

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.
