The consultant will control project scope, PBS/WBS, planning, budget, resources, dependencies, assumptions, risks and issues. Responsibilities also include SteerCo organization, decision preparation, reliable PSR reporting, supplier management and procurement support. The role covers pilots, testing, UAT, acceptance criteria, reconciliation, cutover or rollback and production validation. Change management, communication, user coordination, documentation, knowledge transfer and Move2Run are also part of the assignment.

The assignment is full-time for 24 months, from 3 November 2026 to 2 November 2028, with potentially 440 person-days at 40 hours per week. At least three days per week must be worked on-site at Vivaqua's Brussels headquarters, with hybrid work available.
