## Description

The F-35 doesn't fly without its data backbone. As Senior System & Network Administrator embedded with Belgian Defence at Kleine Brogel Air Base, you will hold a lead position in the ILIAS Solutions team, working in close cooperation with the Belgian Defence team that has overall lead on the programme. You will be responsible for keeping ALIS and ODIN, the Autonomic Logistics Information System and Operational Data Integrated Network, running across the full IT infrastructure that F-35 flight operations depend on. Database administrators on the team manage the data lifecycle; your focus is ensuring the underlying systems, networks, and infrastructure remain available, secure, and performing to the standard a live military flying environment demands.
This is a player-coach position: you lead and support the local ILIAS System & Network Administration team while remaining hands-on across the full infrastructure stack. This role requires physical presence and continuity inside a security-controlled military facility.

Your Mission

What you'll do

 * Lead and support the ILIAS System & Network Administration team, managing priorities and ensuring high-quality delivery across all infrastructure and user-support responsibilities, in close cooperation with the Belgian Defence team.
 * Maintain, monitor, and optimise server, storage (NAS/SAN), and virtualisation infrastructure, including backup and disaster recovery operations and system configuration control.
 * Administer and secure firewalls, routers, switches, and network appliances across LAN/WAN environments, applying strong TCP/IP, VPN, SSL, and Layer 2/3 networking practices.
 * Troubleshoot and resolve system and network issues, providing reliable user support and maintaining network monitoring across the facility.
 * Develop and maintain scripting solutions (Shell, Bash, Batch or comparable) to automate operational and administrative tasks.
