Devops/On call

We are looking for a Site Reliability Engineer with deep knowledge of Linux and distributed systems to help take care of its distributed crawler and ensure all systems are up and running 24/7. Working experience with bare-metal servers and ability to participate in daily on-call rotation are required.

Our system is big part custom OCaml code and also employs third-party technologies - Debian, ELK, Puppet, and anything else that will solve the task at hand. In this role, be prepared to deal with 25 petabytes storage cluster, 2,000 bare-metal servers, experimental large-scale deployments and all kinds of software bugs and hardware deviations on a daily basis.

If you possess a healthy desire to automate everything while being able to quickly resolve urgent issues manually, then we want you! We strive to keep humans away from doing repetitive jobs that can be done by computers and focus instead on foreseeing problems and defining programmatic means to handle them. If there is any new technology that will make our life easier - no doubt, we'll give it a try. We rely heavily on opensource code (as the only viable way to build maintainable system) and contribute back [1]. Occasionally we track down CPU bugs [2].

Our motto is "first do it, then do it right, then do it better". Drop an email to connect@ahrefs.com
