Help us build a better Internet

About Us

At Cloudflare, we have our eyes set on an ambitious goal: to help build a better Internet. Today, Cloudflare runs one of the world’s largest distributed networks that powers more than 1.5 trillion pageviews each month across 5 million Internet properties. More than 10 percent of all global Internet requests flow through Cloudflare’s network. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code.

Our customers range from Fortune 500 companies and nonprofits to small businesses and budding entrepreneurs. Every day, about 12,000 new customers sign up. We’re working to create a faster, more secure, and more reliable experience for anyone online and given the scale at which we operate, our mission is big. Our team is hard at work shaping the future of the Internet by solving some of its toughest challenges. Come join us.

About the Team

Every second, millions of events are generated across Cloudflare’s network. Using the insights derived from this data, the Edge Data Team is responsible for:

  • Driving new feature and protocol development through performance testing
  • Understanding the nature of automated clients that use Cloudflare’s network
  • Providing actionable data on threat patterns to customers and internal teams
  • Using browser telemetry to measure and improve the security of customers’ websites
  • Implementation of edge-side features as required

We write most of our application code in Go, use Kafka as our data streaming system, and use a variety of databases and stream-processing frameworks. Edge-side features are implemented in Lua/Nginx.

The Edge Data Team is small and growing which means you will have an impact from day one. We are committed to creating an environment where team members can produce their best work and grow their skillset.

About You

We are looking for capable, motivated people with a deep interest in delivering performance and security improvements at scale.

Most importantly, you have previous experience or an interest in:

  • Writing and maintaining services with an eye towards flexibility and resilience
  • Building data pipelines that extract meaning from large volumes of data
  • Reasoning about, and debugging, the behaviour of distributed systems
  • Web security and performance, including protocols and browser features

Experience with Go or another strongly-typed language is required. Experience with Kafka, large-scale data storage, C, or Lua is beneficial but not a requirement. Intermediate knowledge of internet protocols (HTTP, DNS, TCP, UDP) is also beneficial.

We welcome applicants from all backgrounds, including those without a computer science degree.

What Makes Us 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. In 2014, we launched Project Galileo, an initiative through which we partner with global NGOs to identify websites at risk of attack and provide the same state-of-the-art mitigation technology already used by Cloudflare’s enterprise customers--at no cost. Project Galileo equips politically and artistically important organizations and journalists with powerful tools to defend themselves against attacks that would otherwise censor their work.

Additionally, in 2016, we announced our partnership with Path Forward, a nonprofit organization that works with companies to create 18-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. With the lofty goal of shaping the future of the Internet, we’re focused on recruiting the best and the brightest, no matter what.

Cloudflare is a security company. A successful background check is required for employment.

Cloudflare hires the best people based on an evaluation of their abilities and effectiveness.  We don't discriminate against employees on the basis of any other personal characteristic or any classification protected by federal, state or local law.
