In defence operations, timing and reliable information shape every decision. Many organizations still rely on fragmented systems, limiting visibility and slowing execution. ILIAS Solutions connects logistics, maintenance, and operations into one integrated platform. This creates a single source of truth and enables teams to act on real time data across strategic, operational, and tactical levels. Large volumes of operational data move continuously between systems. This data reflects maintenance cycles, logistics flows, and asset readiness. Accuracy and consistency directly impact operational outcomes.
You'll validate the data flows that tie together financial records, inventory, and operational readiness across four countries — because a mapping error caught after go-live breaks a programme's budget and timeline in a single move. This role sits at the centre of Patria Group's integration programme, testing the interfaces between SAP S/4HANA and the ILIAS Enterprise Suite fleet management and logistics maintenance readiness solutions across Belgium, Finland, and Latvia.
