THE BACKGROUND

For our client, an EU Financial Institution based in Luxembourg, we are looking for a Senior Business Analyst with extensive experience in ERP transformation and Procurement-to-Pay / Accounts Payable within the financial sector, to join a long-term mission ( 240 days with possibility to extend by 50%).

Please note that the service must be delivered onsite, meaning that you should be located in the Luxembourg area.

YOUR RESPONSIBILITIES

You will support the Client’s ERP Financials Transformation programme, contributing to the definition, structuring and documentation of the Target Operating Model, capability set, business requirements and related procurement documentation.

You will also support ERP tool selection and system integrator procurement by ensuring business inputs, use cases, fit/gap assessments and requirements are structured, documented and traceable for a formal procurement context.

Your focus will be on Procurement-to-Pay processes, particularly Accounts Payable and Payment (invoicing, payment execution, reconciliation), bringing strong functional expertise and proven ERP implementation experience (SAP, Oracle or equivalent).

The programme runs in two phases:

• Phase 1: Definition of a solution-agnostic Group Target Operating Model, capability set and use cases, leading to ERP tool selection.

• Phase 2: Translation of the approved TOM into contractual business requirements, leading to system integrator selection and a fixed-price contractual baseline.

This assignment covers Phase 1 You will report operationally to the Programme Manager and work closely with Stream Leaders, who retain accountability for stream-level decisions and validation.
