Help us build a better Internet

About Us
At Cloudflare, we have our eyes set on an ambitious goal: to help build a better Internet. Today the company runs one of the world’s largest networks that powers trillions of requests per month. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare have all 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 recognized by the World Economic Forum as a Technology Pioneer and named to Entrepreneur Magazine’s Top Company Cultures list.
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

We operate thousands of Linux servers around the world, processing millions of requests each second. To handle loads like that we need to use every technology trick that improves our service. We are looking for 2 EM’s to manage each one of those teams that are critical to our success.  

Team Unimog: 

The team builds systems to manage the utilization of the thousands of servers in our edge network, ensuring that we can deliver our services efficiently and reliably.  We wrote the in-house Layer 4 Load Balancer that touches almost every packet passing through our network. Much work still lies ahead to support the continuing expansion and evolution of Cloudflare’s product suite and edge network. Current projects include extending the load balancer to manage load across multiple data centers. The team is all about taking on challenging problems and delivering solutions that fit our complex technical, operational, and business needs. This team is in London.  

Team DoS: 

Cloudflare operates the most advanced system in protecting against Denial of Service (DoS) attacks in the world. We mitigate more attacks than almost anyone without breaking a sweat. We build the tools that protect both Cloudflare’s infrastructure and our customers against DDoS attacks ranging from L3/4 to L7 in the OSI model.. The attack surface is constantly evolving, thus we need constant improvements. Team is in Austin and London 

In either case: 

You will be managing a highly skilled team of engineers. You will have significant influence on the direction of our edge platform, and you will need to work with many other teams to successfully deliver results. You will guide the team in selecting what projects to take on and in what order. You will communicate the progress of the team to stakeholders in the rest of the company, and ensure that the team is aligned with the needs of the company.  You will be comfortable managing the trade-offs and uncertainties involved in ambitious projects.  You need to be able to communicate effectively with various audiences and work in an ever changing environment where priorities can change rapidly. 

You are expected to lead innovation and help decide on the next big thing to work on. You will foster the professional growth of the engineers within the team.

Desirable skills 

  • Experience in engineering management 
  • Demonstrated technical leadership in distributed networking
  • Visionary - able to strategize on long term goals while still being able to break it down to actionable smaller steps 
  • Good communicator 
  • Comfortable with uncertainty and escalations. 
  • DoS team requires significant engagement with product teams and customers.


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. We released 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 policy and ensure that no user data is sold to advertisers or used to target consumers.
