About the role

Role Summary

Back in 2014, Cloudflare launched Universal SSL to provide all of our customers with the security of encrypted traffic between visitors and Cloudflare’s network. On the day we flipped the switch, we doubled the amount of sites using SSL/TLS on the internet. Since then, we’ve been working on providing even more ways to encrypt traffic easier and more effectively. To better serve our customers, we’re constantly improving our systems for issuing, managing, and deploying TLS certificates. By joining Cloudflare’s SSL/TLS Team, you can help ensure that every site owner has the ability to provide their users with a secure connection.

Your code will help ensure millions of websites have access to encryption. As such, the results of your code will be felt by millions of site owners and billions of visitors every day. We’re continuously providing technology to site owners that was previously only available to the largest organizations. Your contributions will help make the web a faster, safer, better, and more heavily encrypted place.

Cloudflare is looking for a Systems Engineer to help us build services with RESTful APIs and their own datastores using Go and other languages. You will also write and maintain functional specifications for your service, so others know how it works. In this role you will integrate multiple services via message queue systems and evaluate 3rd party and open source tools. You will design and implement alerts, write procedures for ops to handle such alerts, or serve as an escalation point for unresolved operational issues. You will also need to read and understand code from a legacy codebase to migrate logic to a modern services architecture and review the code of fellow engineers via pull requests. We strive to build reliable, fault-tolerant systems that can operate at Cloudflare’s scale.

Role Requirements (Must-Have Skills)

  • Experience writing production-quality code in Go (or other languages with a willingness to learn Go)
  • Proven experience building and operating distributed systems
  • Proficiency with modern Unix/Linux development and runtime environments
  • Strong debugging and troubleshooting skills with attention to detail
  • Track record of delivering well-tested, reliable code for production environments

Desirable Skills, Knowledge, and Experience

  • Experience designing and building RESTful APIs and full-stack applications
  • Familiarity with PKI/TLS concepts and certificate management
  • Experience writing technical documentation and specifications
  • Working knowledge of SQL and relational databases such as PostgreSQL
  • Understanding of distributed systems constraints: performance, caching, data storage/retrieval
  • Experience with message queues (Kafka, RabbitMQ, etc)
