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.

About The Department

Cloudflare's Engineering Team builds and runs the software that handles large amounts of requests on the Internet today. We also build and run the internal tools and platforms that run that software. Individual engineering teams are typically responsible for large areas with considerable impact, and able to execute autonomously within that space to deliver value to their customers – be they internal or external.

Many of Cloudflare's critical internal services run on Kubernetes. These services include those responsible for Cloudflare's control plane and APIs, data analytics and other internal tools used to manage our global network. These Kubernetes platforms are purpose-built from the ground up and run on bare metal Linux in different regions around the world. The scale we work at involves tens of thousands of containers and terabits per second of network traffic. The team takes pride in knowing this platform helps run parts of the global Internet.

About The Team And The Role

The Developer Tools organization delivers a fast, reliable, and secure developer experience by removing workflow friction and providing resilient infrastructure that our internal teams can trust at every stage of the software lifecycle. We build self‐service, resilient, scalable platforms and tools using a combination of Open Source projects, intellectual property, and internal infrastructure. These tools and platforms are used by hundreds of developers at Cloudflare to code, build, test, and deploy their software.

The Developer Productivity team empowers engineers to deliver high-quality software faster via golden‐path workflows, flexible but powerful tools, living standards, and intelligent automation. The role includes both software engineering and DevOps operational responsibilities. The ideal candidate will care deeply about providing other engineers with an excellent development experience, and have a deep understanding of what engineers care about, how they accomplish their day‐to‐day work, and what world‐class developer tooling looks like.

• Ability to break down complex problems into smaller pieces, provide options, talk through trade‐offs, and drive the effort to solve the problem.

Bonus Points

• Worked in a platform engineering team/engineering productivity team in the past.
• Expertise in building and maintaining systems for specific developer tooling domains like build systems, CI/CD pipelines, source control, or automation tools.
• Experience operating Kubernetes on‐premise at scale in capacities including SRE, systems design or architecture.

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's the first consumer‐facing service Cloudflare has ever released. We never store client IP addresses and will continue to abide by our privacy commitment and ensure no user data is sold to advertisers or used to target consumers.
