Confident creating and running Ethernet cables, including terminating RJ45 connectors and testing cable runs.
Excellent problem-solving and diagnostic skills.
Strong communication skills, able to explain technical issues clearly to non-technical users.
Ability to manage multiple tickets and prioritise effectively under pressure.

Nice to Haves

Industry certifications such as CompTIA Network+, CompTIA Server+, LPIC-1, or equivalent.
Familiarity with Docker beyond Portainer (CLI, Compose, building images).
Basic understanding of JavaScript and Bash for reading, tweaking, and writing simple scripts.
Experience with hosting platforms such as Hetzner (or DigitalOcean, Linode, AWS EC2) for provisioning and managing remote servers.
Hands-on experience with Portainer for managing Docker containers and stacks.
