Senior Software Engineer

Description

At the company, we are on a mission to help build a better Internet. 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.

The Zero Trust Connectivity team builds the hub that connects the company One and Zero Trust products such as the company WAN, the company One Client, the company Tunnels, Gateway and Workers VPC. Powering this hub is a set of Rust-based services operating on every one of the data-centers that the company runs. These services route all of the company One traffic end to end. By leveraging the company's incredible infrastructure and programming languages such as Rust, this critical service is safe, performant and secure.

As the company 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 the company's unique architecture and global network footprint.

What Makes the company 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.

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 : 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.
