Since we don't know what team you'll be working on quite yet, here's some things that we do at Cloudflare. This is not a complete list, but gives a good indica
tion of the wide variety of things you might work on.

• A TLS/HTTP proxy to make the connection from eyeball to edge as fast and secure as possible
• Filtering malicious traffic and handling good traffic according to customer configuration

• Optimization of connections from Cloudflare to our customers' origin servers to reduce their load and increase performance
• Our Authoritative DNS server and our public resolver 1.1.1.1.
• Data Science diving deep into HTTP request data, identifying malicious and fraudulent traffic patterns, and building novel solutions for mitigating such attacks.
• Full Machine Learning platform and model development, from feature engineering to model development to release and monitoring.
• One of the biggest data pipelines in the world, operating at well over 250M events per second
• We operate some of the fastest, and most widely distributed services on the Internet. Your work will focus on building robust, secure, and high performance distributed systems. We are a small engineering team operating at a massive scale, so what you do will have a huge impact.

Requirements for any role

If you think some of this list describes you (or what you aspire to be) we would love to talk to you. While not listed as a requirement, we also want to call out that most roles need the flexibility to be on-call outside of standard working hours to address technical issues as needed.

• Experience (and love for) debugging to ensure the system works in all cases
• Experience with a continuous integration workflow and using source control (we use git)
• Designing and building APIs
• Understanding of what it takes to build secure systems
• Confidence to work in multiple programming languages - bonus points for Go and/or Rust

Some team-specific things we think are interesting and want to highlight.

• Understanding systems at the network protocol level, including the differences between what the specs say, and what actually happens on the Internet
• Strong systems level programming skills
• Optimization of complex solutions
• Experience with databases (we use PostgreSQL and Clickhouse)
• Understanding what it takes to build and maintain distributed systems
• Good Unix knowledge, having submitted patches to Operating Systems a huge plus for some roles

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: 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.
