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 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.

About the department
As part of the Cloudflare Engineering organization, SREs are primarily responsible for production reliability. SREs are based in San Francisco, London, Singapore, Austin and Lisbon and use the global distribution to enable follow the sun coverage which allows work to be focused in business hours in each location.
SREs are supported by all engineering teams at Cloudflare who participate in on call schedules for their services. The SRE teams facilitate remediation and follow up of production issues and mature the tooling to enable all engineering teams to self-service on production. Incident follow up work across all engineering teams is prioritized above product innovation and the impact of production incidents influences the priority.
Currently SREs support two main environments: Edge SRE are focused on edge distribution where most client traffic is served. Core SRE are focused on the core services like control plane, data pipeline and other supporting supporting services
Edge SRE project work is organized in four development areas: Platform Engineering, Production Tooling, Hardware Lifecycle and Observability.

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.
220.127.116.11: We released 18.104.22.168 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.
