Your responsibilities
Solution architecture and design

• Own the end-to-end solution architecture for the O2C process stream across SAP S/4HANA Finance and connected solutions, ensuring alignment with the LUCA global template and METRO architecture principles.
• Translate business requirements into coherent functional and technical solution designs covering customer master dependencies, sales-to-billing integration, accounts receivable, incoming payments, bank statement processing, clearing, credit-related integration and financial reporting impacts.
• Lead and support Fit-to-Standard workshops, identify gaps and assess whether requirements should be addressed through standard functionality, process change, approved extensions or interfaces.
• Advise Process Leads and Process Owners on architectural decisions, solution options, dependencies and implications for operations, controls, data and surrounding systems.
• Review and approve end-to-end designs, configuration concepts, functional specifications and integration designs within the assigned architecture scope.

Integration and architectural governance

• Ensure consistent integration across SAP AR, SAP SD, Serrala Autobank and relevant upstream and downstream partner systems.
• Oversee interfaces, extensions and enhancements, minimising unnecessary deviation from SAP standard and protecting solution maintainability.
• Identify cross-stream dependencies with Finance, banking, master data, integration, security, reporting and country rollout teams, and drive them to clear ownership and resolution.
• Ensure solution decisions and deviations are documented, governed and traceable through the appropriate LUCA design and change forums.

Testing, deployment and stabilisation

• Define architecture-relevant acceptance criteria and support preparation of integration, end-to-end, regression and user-acceptance testing.
• Support defect analysis and resolution, including review and approval of solution corrections and required transports within the O2C scope.
• Provide architectural input to data migration, cutover planning, system-readiness assessment and go-live decision-making.
• Support post-go-live stabilisation, analyse recurring issues and identify opportunities for solution and process optimisation.

Experience and knowledge

• Bachelor’s or Master’s degree in Business Informatics, Computer Science, Finance or a related discipline.
• At least 10 years of SAP experience with substantial responsibility for O2C or accounts-receivable solution design in complex transformation or implementation programmes.
• Deep functional and solution-architecture expertise in SAP S/4HANA Finance Accounts Receivable and its integration with SAP Sales and Distribution.
• Hands-on experience with incoming-payment and bank-statement processes; practical knowledge of Serrala Autobank is required.
• Understanding of customer accounting, billing and accounting integration, open-item management, clearing, dunning, payment allocation and reconciliation.
• Experience designing SAP and non-SAP interfaces and coordinating dependencies across business processes, data, integration and reporting.
• Experience with SAP FSCM capabilities is advantageous.
• Experience supporting Fit-to-Standard, testing, migration, cutover and post-go-live stabilisation across at least one full implementation lifecycle.
• SAP Finance certification and retail-industry experience are advantageous.

Ways of working

• Strong analytical and structured problem-solving skills, with the ability to evaluate business needs, solution options, risks and architectural trade-offs.
• Clear and articulate communication with business, functional and technical stakeholders at different levels of seniority.
• Ability to facilitate decisions, challenge constructively and build alignment across process teams, technology teams and implementation partners.
• High level of ownership, quality orientation and attention to detail in a complex multinational programme environment.
• Excellent written and spoken English; willingness and ability to travel when required.

Measures of success

• O2C designs provide an integrated, scalable and supportable solution aligned with the LUCA global template.
• Business requirements are translated into clear architecture decisions with understood process, data, control and integration impacts.
• Cross-stream dependencies and design risks are identified early and resolved before they affect testing or rollout milestones.
• Custom developments and interfaces are justified, governed and kept to the minimum necessary.
• The O2C solution is testable, deployable and stable, with defects and recurring issues resolved sustainably.
