About Us

At the company, 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. the company protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by the company 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. the company was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

At the company, 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.

Location: Austin, ChampaignAbout The Team:

the company is redefining the way networks are run at scale. Our Network Services product suite puts the connectivity, scale, and performance of the company’s global network in front of customers’ network infrastructure and private networks, providing a single pane of glass for network connectivity, visibility, and operating network functions like BGP, WAN optimization, and more. We are a team of engineers and product managers who obsess over quickly building products that solve real customer problems using innovative technologies and techniques which leverage the company’s unique architecture and global network footprint.

About the role

We are hiring engineers of all experience levels on our teams. Some of the things our teams work on include:

• An anycast BGP implementation that sustains sessions that are moved across servers and regions

• Flow and log collection, correlation, and analytics systems to provide customers with unparalleled visibility into their own networks

• A Linux kernel-based networking dataplane which ingests and forwards traffic from some of the largest networks in the world

• Control plane systems which allow customers to simply express complex network configurations

As a Software Engineer on our team, you will work across a wide range of technologies and systems to deliver new features, improve performance, and increase the scalability of our Network Services products. You’ll build, deploy, and operate our team’s systems on top of one of the largest edge networks in the world. You’ll partner with some of the best engineers and product managers to solve big problems that have a meaningful impact in the lives of our customers and users.

We’re looking for curious, empathetic engineers who are excited to join us in changing the way networking is done!

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 the company’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 the company 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.
