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. 

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! 

About the department

Cloudflare’s Resiliency Engineering Team builds and runs the systems and software that support our solutions that handle trillions of requests per month. Resiliency Engineering ensures all of the new and existing features and functionality that Cloudflare offers can be managed at scale and meet the needs of our massively growing customer base.


The Infrastructure Tooling Team within the Resiliency Engineering organization is responsible for defining, building and supporting the tools that can be leveraged by the rest of the Infrastructure Engineering team to manage our infrastructure at scale.

What you'll do

In this role you’ll have an opportunity to work on a number of different projects over the course of a year.    These projects are critical to Cloudflare’s success and will often be developed in incubation mode with a focus on agile and iterative delivery to prove and build value over time.  A sampling of the areas you may get a chance to work on are a service to automate firmware updates, tools to manage our IP addresses and adding complex capacity dashboard functionality.  

Because you’ll be solving problems of great significance, and shaping the future of the Internet, you are a growth-oriented individual who enjoys being outside of your comfort zone in a fast-paced environment.

Examples of desirable skills, knowledge and experience

As an ideal candidate for this position, you are curious, hard-working, and passionate.

A rough list of the skills we would love to see you bring:

  • Programming experience in Go, Python or similar languages
  • Experience (and love) for debugging to ensure the system works in all cases
  • Designing and building APIs
  • Great oral and written communications skills
  • Desire to learn and improve
  • CS degree or equivalent experience
  • Passion for solving unique problem and learning to understand complex systems

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.

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.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
