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.

About the role

We’re looking for a Senior Software Engineer to join our Cloudflare One Client team. You will be working on the cross-platform app and lower-level implementation of our Cloudflare One Client Desktop and Mobile Apps, which protects devices by securely and privately sending traffic from those devices to Cloudflare’s global network, which can apply advanced filtering and Cloudflare One policies.

What you'll do

In your role, you will use cross-platform frameworks along with platform-native languages & APIs to implement user-friendly apps that run on desktop and mobile platforms. You will also use Rust alongside platform-native languages and APIs to implement high-performance networking code for both our mobile and desktop apps.

You will be most successful in this role if you have a good understanding of user-interface programming, the intricacies of different platforms (mobile and desktop), experience working on multi-platform code, a decent understanding of lower-level operating system concepts (virtual memory, multi-threading, process lifecycle, etc.) and networking concepts & protocols (VPNs, TCP/IP, etc.). You will also have to interact with other languages, such as Flutter, Swift, Java, Kotlin, C#, Rust, C++, and C. You’ll be expected to improve the code quality and to build solid, testable, and well-documented foundations.

As a Senior Software Engineer, you will be expected to lead the design and implementation of major development projects, working closely with our product managers, designers and other teams to implement customer-impacting features. You will work on stimulating problems born out of the scale of our deployment, and the stringent quality, performance, and security requirements of our product.

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.
