About the Dept

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 all of the new and existing features and functionality that Cloudflare offers can be managed at scale and meet the needs of our massively growing customer base.

Responsibilities

An engineering role at Cloudflare provides an opportunity to address some big challenges, at scale. We believe that with our talented team, we can solve some of the biggest security, reliability and performance problems facing the Internet. Just how big?

• We have in excess of 340 Terabits of network transit capacity
• We operate 330+ Points-of-presence around the world
• We serve more traffic than Twitter, Amazon, Apple, Instagram, Bing, and Wikipedia combined
• Anytime we push code, it immediately affects over 200 million internet users
• Every day, up to 20,000 new customers sign-up for Cloudflare service
• Every week, the average Internet user touches us more than 500 times

We are looking for talented Software Engineers to build and develop the platform which makes Cloudflare customers place their trust in us. Our Software Engineers come from a variety of technical backgrounds and have built up their knowledge working in different environments. But the common factors across all of our reliability-focused engineers include a passion for automation, scalability, and operational excellence. Our Infrastructure Software Systems and Automation team focuses on the automation to scale our infrastructure.

Our team is well-funded and focused on building an extraordinary company. This is a superb opportunity to join a high-performing team and scale our high-growth network as Cloudflare's business grows. You will build tools to constantly improve our scale and speed of deployment. You will nurture a passion for an 'automate everything' approach that makes systems failure-resistant and ready-to-scale.

Cloudflare Software Engineers focus on automating our infrastructure installations and decommissions at scale. We enable our Data Centre Engineering teams by allowing them to install new data centers, replace servers and networking in existing data centers as quickly and efficiently as possible while not impacting existing infrastructure and customer services. While our focus is on automation and accurate asset tracking, there is an element of ongoing operational support of Data Center Engineers and other teams. We also review upcoming hardware changes and update automation and configuration management to cater to these advances.

Many of our Software Engineers have had the opportunity to work at multiple offices on interim and long-term project assignments. The ideal Software Engineering candidate has strong knowledge of Rust, with Python, Golang, and TypeScript being an advantage. As we are automating server and networking installations, knowledge of Linux, Hardware and Networking is ideal.

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.
