Senior/Medior Linux System Engineer

Mendix, Rotterdam

We help enterprises achieve their digital goals


Mendix is on a mission to fundamentally reinvent the way applications are created, by abstracting the process and enabling everyone who has a stake in an enterprise’s digital future — business people and analysts, web developers, software engineers, even CEOs — to meaningfully participate, thereby creating better applications faster. Our goal is simply to create the future of software development.

Mendix is looking for a Senior/Medior Linux System Engineer for maintaining, managing and improving our hosting environment. The latest edition of the Mendix Cloud (v4) runs on AWS but we have a large install base of the previous version (v3). Some of our most important customers will keep relying on v3 for the next few years, so keeping it stable and secure is very much vital to our business.

You’ll help our customers drive digital innovation by:

  • Managing the thousands of(highly standardized) Virtual Machines powering Mendix Cloud v3
  • Maintaining the physical servers and networking stack
  • Applying security and operating system updates to thousands of systems in a coordinated way
  • Creating tools to automate standard operations, like: VM resizes, OS upgrades, database upgrades
  • Keeping a general uptime of 99,99%+
  • Conquering technical challenges by finding innovative solutions. You'll have the opportunity to harness all your skills to make a difference in your role
  • Getting things done mentality

Our technology stack is mostly based on open source technologies and the Debian GNU/Linux distribution:

  • Virtualization: Xen
  • Networking: IPVS, OSPF and BGP using BIRD
  • Hardware: high end servers, switches and SAN
  • Operating systems: Debian GNU/Linux
  • Configuration management: Puppet
  • Version control: Git, Gitlab, Github
  • Databases: PostgreSQL
  • Storage / Filesystems: ext4 / BTRFS / LVM2
  • Automation: Python, Ansible
  • Software packaging: Debian packages
  • Monitoring: Nagios / Munin / Icinga2 / Collectd
  • HTTPS Routing: Nginx
  • Colocation: 3 data centers in The Netherlands

We are very interested in speaking with you:

  • If you think you can get up to speed quickly and have lots of experience in similar systems. You do not need to have knowledge of all the technologies listed above.
  • We need you to maintain the rock-solidness of Mendix Cloud v3 and add the best features from that Cloud environment – and everything you’ve learned during your been-there-done-that career – to our Mendix Cloud v4 environment.
  • You will be working in a team that is responsible for both our own hardware (Mendix Cloud v3) and AWS infrastructure (Mendix Cloud v4), and will be surrounded by colleagues that are well versed in both technology stacks.
  • We offer training on AWS and plenty of time to work with Cloud based technologies.
  • You will be 3rd line on-call 24/7 about one week a month.
Experience a culture like no other at Mendix:

Relaxed environment with the coolest office in the Netherlands, and great view of the Erasmusbrug.
Everyone is appreciated for their skills and ideas, regardless of their mother tongue, ability to grow a beard, choice of keyboard or other crazy hobbies.
Monthly crafting days allow us to explore side projects or try out cool new technologies and share our experiences with the rest of the organization(we also have a fixed individual budget for training or visiting conferences).
Teams are autonomous, responsible for coming up with innovative ideas that contribute to the bigger picture.
