  • You’re in charge of overseeing the safe operation of our systems every day. If something comes up, our monitoring will notify you, you’ll immediately step in and contribute to the smooth operation of our infrastructure – tens of thousands of our customers count on it! You’ll then try to uncover the root cause of the problem, either on your own or with the help of other experienced admins, and ideally solve it in such a way that it will never arise again. We keep an internal record of all incidents using JIRA tickets. The goal is to have problem-free systems without the necessity of an intervention.
  • 4-6 times a month, you’re on system surveillance night duty. Your work starts in the afternoon, at around 1pm. From 7pm on, you’re on-call and if there’s an outage or another problem, our monitoring will give you a call. You check what’s happening and address the problem. You remain on-call until 8am. We have a similar 24-hour surveillance regime during weekends and state holidays.
  • Apart from day and night surveillance, you can also expect project days devoted to actively improving our existing solutions – either those that are in-house or private solutions for our large customers. You educate yourself, train your colleagues, check up on our data centers or, in case of large-scale projects, meet with partners. We expect you to take initiative in devising solutions that would improve the infrastructure and services for our clients. We’ll be happy to support your ideas.
  • In most cases, our systems run on the Ubuntu LTS platform managed by SaltStack config management. Our virtual servers run on the OpenStack platform. If you have experience with it, great; if not, no worries! We’ll be happy to fill you in on all our technical solutions over the first few months. Our team has several experts in different areas and we’ll be happy to show you everything during training.
  • You’ll be taking care of:

    • a large web cluster that we call IT1.3
    • over 200 servers, 400 pieces of cpu, 3200 physical cores/6400 logical cores, 30+ TB of RAM, 400 TB of RAW SSD disk capacity
    • a database cluster
    • mail servers and load balancers
    • OpenStack architecture and virtual servers
    • internal systems and applications in Docker containers
    • private solutions tailored to our customers’ needs
    • the ZFS file system that gives us excellent control over backups and disaster-recovery solutions


  • concepts such as web hosting, web server, virtual server or storage are a matter of course for you
  • you’ve mastered the configuration of LAMP, reverse proxies, MySQL servers
  • you know RAID, LVM, and the difference between a RAID, a backup and a snapshot
  • a good theoretical and in-depth understanding of Linux regardless of its distributions and uses, or alternatively, experience with your own LFS, Gentoo, ArchLinux or *BSD
  • you’re not afraid of experimenting and problem-solving; you love to learn and improve
  • you have experience with configuring a solution with a cluster or you’re at least familiar with its upsides and downsides
  • you enjoy using git, config management, bash
  • you’re curious about how systems work and love looking under the hood


  • senior-level colleagues that will be happy to teach you anything you don’t feel comfortable in
  • discussions over system solutions, designing large architectures and implementing them
  • the opportunity to participate in lectures and conferences around the world, be it as a participant or a lecturer
  • an opportunity to take language courses (English, German)
  • you’ll get trained in-house (we organize in-house workshops)
  • you can do a fair share of sports (a Multisport card, a workout system in the office)
  • you’ll definitely have a lot of fun here (hackathons, barbecues, breakfasts, a Christmas party)
  • 6 extra vacation days and the possibility of an occasional home-office
  • team building activities such as paintball, jogging, biking or simply a shared beer
I go Up

I'm in!

First, you’ll get a short technical assignment. Then you'll get a call from Lucia from HR and have a chat about what we both expect from our cooperation. During the more personal face-to-face, we’ll go over your experience in more detail and you can ask us anything and everything about the job offer – all of that to make sure we’re a good match for each other. You’ll meet us in this line-up:
Tomáš Srnka
