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 Python and Golang, with Rust an advantage. As we are automating server and networking installations, knowledge of Linux, Hardware and Networking is ideal. We prefer to hire experienced candidates; however raw skill trumps experience and we welcome strong junior applicants.

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.
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.
