Site Reliability Engineer (DevOps)


Site Reliability Engineers are responsible for the keeping and many other GitLab production systems running smoothly 24/7/365. They're developers  specialising in systems, whether it be networking, or the Linux kernel, or even a specific interest in scaling, algorithms, or distributed systems. is a unique site and it brings unique challenges: it’s the biggest  GitLab instance in existence; in fact, it’s one of the largest single-tenancy  open-source SAAS sites on the internet. The experience of our production  engineers feeds back into other engineer groups within the company, as well as  to GitLab customers, running on-premise installations. Responsibilities: 

  • Be on a PagerDuty rotation to respond to availability incidents and 
  • provide support for service engineers with customer incidents.
  • Use your on-call shift to prevent incidents from ever happening.
  • Manage our infrastructure with Chef, Terraform and Kubernetes.
  • Make monitoring and alerting alert on symptoms and not on outages.
  • Document every action so your learnings turn into repeatable actions and then into automation.
  • Improve the deployment process to make it as boring as possible.
  • Design, build and maintain core infrastructure pieces that allow GitLab scaling to support hundred of thousands of concurrent users.
  • Debug production issues across services and levels of the stack.
  • Plan the growth of GitLab's infrastructure.


  • Think about systems - edge cases, failure modes, behaviors, specific implementations.
  • Know your way around Linux and the Unix Shell.
  • Know what is the use of config management systems like Chef (the one we use)
  • Have strong programming skills - Ruby and/or Go
  • Have an urge to collaborate and communicate asynchronously.
  • Have an urge to document all the things so you don't need to learn the same thing twice.
  • Have a proactive, go-for-it attitude. When you see something broken, you can't help but fix it.
  • Have an urge for delivering quickly and iterating fast.
  • Share our values, and work in accordance with those values.

Projects you might work on: 

  • Coding infrastructure automation with Chef
  • Improving our Prometheus Monitoring or building new Metrics
  • Helping release managers deploy and troubleshoot new versions of GitLab-EE.
