About you

Your UNIX / Linux systems and router / firewalls are lucky to have you as their admin. You have a passion for designing and building systems that work and keep working, rain or shine.

As an engineer you have a critical and hands-on approach to software and technologies. You like finding ways to make your deployment and maintenance jobs easier, so you can spend more time fixing, improving, innovating and learning new things. As a hacker you know that learning hands-on often works just as good or better than reading a manual. You prefer open source code over 'enterprise' software and you feel the journey is half the fun. As a colleague, you can work independently, but also like working closely together and sharing responsibilities for the work at hand. You appreciate the human factor in technology.

Skills and competencies:

  • Fluency in English,
  • Fluency with UNIX/Linux user land environments (Debian preferred),
  • Experience with or solid knowledge of most of the following systems:
    • Network protocols and tools (TCP/IP, routers, firewalls, VPNs, Ethernet, VLANs, Wireshark/tcpdump),
    • Webserver and proxies (Apache, Nginx and HAProxy),
    • Relational databases (MySQL, MariaDB),
    • Containers and clusters (LXC, chroots, Docker and/or Kubernetes),
    • Network and cluster file systems (NFS, Ceph),
    • Configuration automation (Ansible, Chef, CFEngine),
    • Monitoring tools (Grafana, Prometheus),
    • Linux kernel and KVM and/or Xen hypervisors,
  • Programming skills in at least 1 of { Python, Perl, C, bash, Go },
