Job Technologies
Your role in the team
- 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.

Our expectations of you
Qualifications
- 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 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.
Experience
- 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 have experience with data technologies like ClickHouse, MariaDB, and PostgreSQL.
