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, London, Austin

About the team

The Zero Trust Connectivity team builds the hub that connects Cloudflare One and Zero Trust products such as Cloudflare WAN, Cloudflare One Client, Cloudflare Tunnels, Gateway and Workers VPC. Powering this hub is a set of Rust-based services operating on every one of the data-centers that Cloudflare runs. These services route all of Cloudflare One traffic end to end. By leveraging Cloudflare's incredible infrastructure and programming languages such as Rust, this critical service is safe, performant and secure. As Cloudflare Zero Trust set of features evolves, this team is responsible for evolving these hub services to deliver those new capabilities while guaranteeing scalability and reliability as top priority.

We are a team of engineers who obsess over building reliable services which leverage Cloudflare's unique architecture and global network footprint.

About the role

As a software engineer on the Zero Trust Connectivity team, you will contribute across a wide range of technologies and systems to deliver new solutions that connect Cloudflare One products together.

This work requires close collaboration with other teams while leveraging powerful frameworks and libraries that power many Cloudflare products. Our technology stack includes Rust, Linux networking, Clickhouse, SaltStack, Prometheus, AI harnesses, and our own Cloudflare Workers platform. We're looking for determined, curious, empathetic engineers to join our team!

Able to work across teams and level common, sustainable solutions
Creative, open-minded, collaborative problem solver
Focus on clarity in written and verbal communication
Leveraging AI coding assistants to accelerate development

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.

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