About Us

At Cloudflare, we have our eyes set on an ambitious goal: to help build a better Internet. Today the company runs one of the world’s largest networks that powers approximately 25 million 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! 


About the team

We are a team of software engineers writing and running big critical distributed systems. When we deploy, we deploy on thousands of servers across 300 data centres all around the globe.

We believe solid automation and testing increases productivity and make engineers happy. We already have automation, k8s, CI pipelines and testing in place but we are looking for somebody to help us drive more projects on this area.

You will work on helping us improve our automation, tooling and replacing some of it with better technology. There is also the opportunity to help us writing Go for our distributed systems.


What you'll do

Quicksilver is Cloudflare’s distributed key-value store. It replicates our data all around the world, over thousands and thousands of servers and around 300 data centers. It handles all kinds of network conditions and is queried multiple times whenever a request crosses our network.

In this role, you can expect to work on automation and orchestration systems that deploy across thousands of physical servers. Systems that decide how the replication topology should be across our services. CI pipelines that allow us to deploy with confidence changes that affect immediately mission critical systems. Monitoring systems that allow us early detection of symptoms caused by performance and integrity degradation on our replicated database. We use a variety of tools, some integrated with the company platform, some other are team specific which are required to connect and run all these systems as smoothly as possible.

You will contribute directly on our orchestration, deployment and rollback plans, automation, operation, monitoring, alerting and troubleshooting. If working on non-trivial engineering problems to achieve reliability at scale excites you, you might be a match for this role.

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: We equip politically and artistically important organizations and journalists 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: We created 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.

Path Forward Partnership: Since 2016, we have partnered with Path Forward, a nonprofit organization, to create 16-week positions for mid-career professionals who want to get back to the workplace after taking time off to care for a child, parent, or loved one. We released 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.
