Mission & Company Overview

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 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. 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!, We are looking for talented Systems Reliability Engineers to build and operate our Edge platform running in more than 320 cities in over 120 countries. Our SREs come from diverse technical backgrounds and have built up their knowledge working in different environments, but common factors across all of our reliability focused engineers include a passion for automation, scalability, and operational excellence. We support our services in a "follow the sun" model with offices in East Asia, Europe and North America. This is a superb opportunity to join a high performing team and scale our high growth network as Cloudflare's business grows. We live at the boundary between systems, network, and software, and love improving the glue that holds them together. Working with us, you will build tools to constantly improve service availability, performance, and operational velocity. You will nurture a passion for an "automate everything" approach that makes systems failure resistant and ready to scale. SREs focus on the immediate state and functionality of the Cloudflare platform around the world, leveraging an array of monitoring, alerting and diagnostics tools while developing and enhancing the Cloudflare platform and its capabilities. We own a wide portfolio of applications and services, running a tight feedback loop of developer and operator patterns. The ideal SRE candidate has a passionate curiosity about how the Internet fundamentally works and has a strong knowledge of networking, Linux and TLS along with coding ability in Go or Python.

What Makes Cloudflare Special? We are 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. Sound like something you'd like to be a part of? We'd love to hear from you!
