Our Data Org is composed of several key teams and you could contribute to any of the following areas:

• Data Delivery: You will build and operate our distributed data delivery pipeline a high-throughput low-latency system (primarily written in Go) responsible for ingesting processing and routing massive volumes of data from across Cloudflares global network to multi-core destination.
• Analytical Database Platform:
• Data Retrieval: Be responsible for building the customer-facing products that make data accessible and actionable. This includes developing our public GraphQL API building robust log delivery solutions and integrations with customer destinations and contributing to our alerting products which empower users to configure and receive near real-time alerts based on the logs and metrics observed by our data platform.

What Makes Cloudflare Special

Were not just a highly ambitious large-scale technology company. Were 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 weve equipped more than 2400 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 Cloudflares 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 weve 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. Heres the deal - we dont 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.
