Non-SAP Integration Lead — Oracle Fusion & Specialised Billing/AP Systems

Lead discovery and interface design for each non-SAP source system (Oracle Fusion Payables via REST/SOAP; specialised billing/AP and vendor-portal platforms via APIs, batch/MFT with SFTP and PGP, or file exports); maintain the interface catalogue and data contracts. Define per-system testing and post-go-live validation approaches equivalent to the SAP SIT/UAT process; document environment and landscape details for each system. Design and deliver the web-upload portal path (template upload with SSO) for entities without AP/AR source systems. Coordinate with third-party system owners and vendors; manage change control and interface readiness across delivery waves. Lead 2–3 integration developers; own unit-test evidence, SIT defect resolution, cutover and hypercare for non-SAP interfaces.
