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.

About the department

Cloudflare’s Resiliency Engineering Team builds and runs the systems and software that support our solutions that handle trillions of requests per month. Resiliency Engineering ensures that all new and existing features and functionality that Cloudflare offers can be managed at scale and meet the needs of our massively growing customer base.

The Infrastructure Tooling Team within Resiliency Engineering is responsible for defining, building and supporting tools and services used across Cloudflare to manage its infrastructure. These tools enable both Cloudflare’s daily operation and its relentless growth.

What you'll do

In this role you’ll have an opportunity to work on our internal infrastructure control plane application “Zinc”. Zinc is a Rust application that is used to manage our global fleet of servers and network devices. Zinc answers every device’s question: what am I, what do I do? The service is high performance, highly available, and is special in that it also shares few dependencies with most other Cloudflare services, since most systems have a dependency on Zinc.

Your work on Zinc will directly affect the efficiency and resilience of Cloudflare's vast global server and network infrastructure. If you are passionate about optimizing and scaling globally distributed systems, this may be the team for you!

Because you’ll be solving problems of great significance, and shaping the future of the Internet, you are a growth-oriented individual who enjoys being outside of your comfort zone in a fast-paced environment.

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!
