SAP Expert - Accounting & Controlling

OneFinance 2026 is a multi-country, multi-entity Finance Transformation Program sponsored at Group level and currently active across 8+ countries and 30+ legal entities. The program is built on SAP S/4HANA as its core ERP, integrated with SAP BTP (Business Technology Platform), Ivalua (P2P), ServiceNow (financial services & request management), Tagetik (CPM/consolidation), and SAP FPSL/GLPD for IFRS 17 and IFRS 9 compliance. The program covers full accounting standardization, record-to-report process harmonization, and digital transformation of Finance operations across the Group, in close partnership with Accenture, PwC, and BCG.

We are looking for a Senior SAP Expert** with deep expertise in Financial Accounting (FI) and Controlling (CO) modules to join the OneFinance 2026 delivery team. Working within an international, fast-paced transformation environment, you will be the go-to functional and technical authority for all SAP accounting and controlling processes — from blueprint design through to hypercare and continuous improvement.

This is a high-visibility, high-impact role. You will collaborate daily with Finance process owners, system integrators, and IT architects, and your work will directly shape how the Group runs its financial operations across Europe and beyond.

Key responsibilities

• SAP FI/CO Design & Configuration: Lead the functional design and configuration of SAP S/4HANA FI and CO modules, aligned with Group accounting standards and IFRS requirements.
• Systems Integration: Ensure robust data flows between SAP and integrated platforms — Ivalua (P2P/procurement), ServiceNow (financial requests), Tagetik (consolidation and planning), and other country-specific systems. Define interface specifications and validate end-to-end accounting impacts.
• Month-End & Period Closing: Define and optimize the Group month-end closing process within SAP, including intercompany reconciliation, accruals, depreciation runs, and financial reporting cycles. Support country teams during go-live and stabilization phases.
• Process Harmonization & Optimization: Analyse existing country-level accounting processes and drive standardization across entities. Identify automation opportunities within SAP (e.g., using SAP BTP extensions or Fiori-based workflows) to reduce manual effort and improve data quality.
• Testing & Quality Assurance: Own the functional testing strategy for FI/CO: define test scripts, coordinate SIT and UAT cycles, track defects, and ensure that resolution meets business requirements before each country go-live.
• Stakeholder Engagement & Training: Act as the primary FI/CO point of contact for Finance process owners, internal audit, and external partners (Accenture, PwC). Design and deliver functional training for local Finance teams across rollout countries.
• Documentation & Governance: Produce and maintain high-quality functional specifications, process documentation, and configuration rationale in line with program governance standards. Contribute to design authority sessions and change control processes.
