Job description

Modern office space with very good transport connections, and at some locations, a subsidized canteen and various free drinks
Various employee discounts for activities and products
Numerous training and development opportunities to enhance your skills
Various health offers, such as sports and health courses, to keep you fit and healthy
Employee events such as summer and winter parties, as well as workshops, to foster team spirit

Requirements

You have experience with DNS / DHCP / proxy / time technologies such as PowerDNS (authoritative, recursor, dnsdist), ISC DHCP (experience with or appetite for Kea is welcome), Squid, and chrony
You are skilled in platform and automation tools like Enterprise Linux 9, Puppet (GitOps), BIRD, rsyslog, and collectd
You are proficient in languages such as Python, Go, Java, Bash, and the classic Unix toolbelt (awk, sed, git) that still does more than people expect
You have experience with data technologies like ClickHouse, MariaDB, and PostgreSQL
You do not need to have mastered all of these on day one, but you are the kind of engineer who is comfortable reaching for the right one and going deep when it matters
You have operated DNS, DHCP, or comparable network services in production, ideally at scale and under real reliability obligations
You read RFCs for fun, debug with packet captures, and are not satisfied by “it works again” without knowing why it broke
You automate by default and treat configuration as code
You bring radical candor, saying the uncomfortable thing early in service of the work, not the ego
You think in terms of blast radius, using AI-assisted tooling in development and test workflows, but ensuring production changes are always human-gated, as risk awareness is a feature, not a brake

Benefits & conditions

You operate, harden, and evolve our authoritative and recursive DNS, DHCP, forward-proxy, DNS and IP Management (DIM), and NTP services so they stay boringly reliable at internet scale
You automate everything that should be automated, using infrastructure as code in Puppet, reviewed and version-controlled, and remove the toil that does not need a human
You instrument and measure by building the metrics, dashboards, and signals that tell us what our services are actually doing, because we cannot improve what we cannot see
You drive root-cause analysis and lasting fixes through structured ITIL Incident, Problem, Risk, and Change management, making our work and challenges transparent on purpose
You take part in the team’s on-call rotation for this KRITIS/NIS2 infrastructure, with your turn coming up roughly once a month, and use what you learn on-call to make the next on-call quieter
