Secures websites and runs apps on its network
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. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.
At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.
About the Team
Cloudflare operates one of the largest and most interconnected anycast networks on the Internet. To make that happen, a complex orchestra of IP address configuration and distributed systems need to be in harmony to deliver packets from users, through our edge network and then onwards to our customers origin servers or networks.
On the Addressing team, you will architect, program, and maintain core software services that enable large corporate networks to be protected by Cloudflare. Recent projects range from IP conservation efforts, supporting use cases for Policy driven IP address assignment, designing traffic engineering tools that improve the quality of service for billions of users around the world, and building customer APIs to control BGP dynamically.
The Addressing team works closely with our system reliability engineers, network engineers and product engineering teams to build automated systems that span the entire Cloudflare stack.
We are looking for talented Software Engineers to join our small but growing team. You will work on a range of microservices written mainly in Go. You’ll be designing and developing new APIs and data models to manage our rapidly expanding addressing needs.
The ever growing suite of Cloudflare products and services means our addressing tools are always evolving. You will have the opportunity to take on very impactful projects critical for Cloudflare. You will spend time learning the inner workings of our edge routers, servers, DNS and IP provisioning pipelines. You will work closely with other engineers to understand their needs and create scalable platforms to be used across the company.
Some of the technologies we use include Go, PostgreSQL, Docker, Kafka, Lua, Clickhouse, SaltStack, Prometheus and the usual Unix/Linux tools and workflows. We strive to build reliable, fault-tolerant systems that can operate at Cloudflare’s scale.
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 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.
