Role Description At apeirum, we embed senior engineers into growing European companies — no juniors dressed up as seniors, no agency layers, full accountability from day one. We're now looking for a DevSecOps / Infrastructure Engineer who runs self-hosted, security-first infrastructure end to end: from hardening a Linux server to operating multi-node Kubernetes in production, to keeping an ISO 27001 ISMS audit-ready. This is a hands-on role for someone equally comfortable debugging a failing cluster upgrade in the morning and writing the change-management evidence an auditor reads three months later. If you like owning infrastructure rather than just consuming a managed cloud, you'll fit right in. The setup depends on where you're based: a permanent employment contract for candidates based in Spain, or a freelance/contract engagement for candidates based in Portugal. Fully remote within Spain and Portugal, on CET working hours.
