About the Role

We are seeking an experienced SAP S/4HANA Finance Solution Architect with deep Source-to-Pay expertise to partner with our Finance and Accounting teams during a major S/4 upgrade/implementation program.

This role is not a hands-on configuration role — the primary SI partner will perform configuration and build. Instead, this consultant will act as a Solution Architect, design advisor, and functional guardian, ensuring the solution meets business needs, aligns with best practices, and fits our end-to-end Finance and Procurement processes.

The ideal candidate brings strong hands-on AP/S2P process depth, SAP Ariba integration and migration experience, and the ability to guide, challenge, and validate SI-led delivery across the full Finance and Procurement landscape.
