Confident creating and running Ethernet cables, including terminating RJ45 connectors and testing cable runs.

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.
Working knowledge of MySQL, including basic administration, queries, backups, and user management.
Knowledge of firewall configuration and network security best practices.
Experience working in an EdTech or training environment.
