A major public sector organisation in Wallonia is implementing and governing a financial ERP program for a large city, covering accounting, budgeting, expenditure, revenue and treasury. As the senior ERP Program Manager, you will align business requirements with the ERP solution and lead change management across finance, IT and executive governance, while keeping the program coherent alongside an established mainframe landscape.
The mission
The program spans accounting, management control and treasury, with delivery organised across multiple phases and entities. Its functional scope includes detailed municipal accounting for expenditure, revenue and budget management, governed by the legislation applicable in Belgium, together with regulatory compliance, public procurement, financial standards, closings and consolidation. The work matters because the organisation needs one consistent governance model connecting the financial operating model, the formal requirements specification and the technical solutions being deployed.
You will manage the program end to end, from framing and planning through budget tracking, reporting, governance and evolution. You will coordinate finance functional experts, IT teams, integrators and software vendors, while reporting to the finance director, general director or inspector general, and IT director. Your decisions will translate business requirements into priorities, manage risks, dependencies and escalations, and keep delivery aligned with the approved ERP direction. This senior ERP Program Manager role in the public sector requires detailed knowledge of municipal finance and executive stakeholder management with C-level stakeholders.
