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.

The Assignment aims to define a solution-agnostic, standard-first Target Operating Model aligned with market practices and standard ERP capabilities, while challenging legacy-driven processes and unnecessary complexity. 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.

YOUR PROFILE

Mandatory Qualifications/Experience:

• University degree in Finance, Accounting, Business Administration or a related field

• 15+ years of experience in business analysis, ERP-enabled transformation programmes or large-scale business process transformation initiatives

• Strong understanding of Procurement-to-Pay processes, with emphasis on Accounts Payable and Payment processes (e.g. invoicing, payment execution, reconciliation), and their interdependencies with core finance processes

• Demonstrated experience in the definition and structuring of Target Operating Models, business processes and functional requirements in complex organisational environments

• Proven experience in ERP implementation programmes involving leading enterprise solutions (e.g. SAP, Oracle or equivalent), including participation in design, fit/gap analysis and solution assessment

• Experience supporting ERP selection processes and/or system integrator procurement, including preparation of use cases, structured business inputs and evaluation artefacts, with attention to clear and traceable documentation in an auditable context

• Experience interacting with multiple stakeholders (business, IT, vendors, external partners) in a structured and multi-stakeholder environment

Preferred Experience:

• Strong understanding of standard ERP capabilities and best market practices, and the ability to position business requirements accordingly

• Familiarity with business analysis methodologies, process modelling and requirements structuring techniques

• Experience in financial institutions, public sector organisations or regulated environments is considered a strong asset

Competencies and Skills to be Demonstrated:

• Strong analytical and problem-structuring skills, with the ability to translate business needs into structured, consistent and decision-ready deliverables

• Ability to critically challenge existing processes, assumptions and legacy-driven practices, and promote simplification, standardisation and alignment with standard ERP capabilities

• Ability to distinguish between business requirements aligned with market practices and ERP standards and those driven by legacy constraints

• Strong communication and facilitation skills, including the ability to support and structure workshops with business stakeholders and subject matter experts

• Ability to produce high-quality documentation (process maps, requirements, analyses, fit/gap assessments) with a high level of clarity, consistency and traceability

• Ability to work effectively in a multi-stakeholder environment, including coordination with Stream Leaders, SMEs, Programme Management and external partners

• Ability to contribute to structured decision-making by providing clear analysis, options and articulation of trade-offs

• Strong attention to detail, organisational skills and ability to meet deadlines in a structured programme environment

• Ability to operate in a controlled and auditable context, ensuring consistency and traceability of inputs, analysis and outputs
