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.

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!

Available Locations: Austin, Lisbon, London

Hiring will be focused on those residing within the greater Austin, TX, London, UK, & Lisbon, Portugal metro areas. It will be a hybrid role, with the expectation of 2 days per week in the office.

We're hiring Software Engineers at all levels. This is a single pipeline position.

About the Team

Cloudflare is redefining the way networks are run at scale. Our Network Services product suite puts the connectivity, scale, and performance of Cloudflare’s global network in front of customers’ network infrastructure and private networks. We’re looking for curious, empathetic engineers who are excited to join us in changing the way networking is done!

The Cloudflare Network Interconnect (CNI) team works with Rust, Linux, and cloud technologies to build and manage servers and high speed networking switches at Cloudflare locations, supporting our public CNI product. We are looking for engineers who are equally as interested in building their own Linux-based operating systems as they are in building user-friendly HTTP APIs, and equally as interested in high speed networking as they are in writing good Rust code.

About the Role

As a software engineer on the CNI team, you will be a key technical contributor to the control and data planes of custom network infrastructure, operating systems, and APIs supporting our product. You will enable customers of Magic Transit, Magic WAN, and other Cloudflare products to connect with Cloudflare over private and high speed data center interconnects.

You will build software on top of one of the largest edge networks in the world, and partner with some of the best engineers and product managers to build robust, automated systems driving hundreds of gigs of customer traffic.

Desired skills, knowledge, and experience

3 years of relevant Software Engineering or SRE experience
BS/MS in Computer Science or equivalent experience
Rust programming
Experience building on top of Linux networking primitives - e.g. ip, tc, network namespaces, etc
Familiarity with network engineering tools and protocols used in data center switching and routing - e.g. BGP, BFD, VXLAN, etc
Experience designing and integrating RESTful APIs and backend systems, especially asynchronous architectures and those deployed onto serverless platforms like Cloudflare Workers
Experience with running virtual machines on Linux
Able to work across teams and level common, sustainable solutions

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.
