• Troubleshoot transaction data mapping, tax calculation discrepancies, and interface failures
• Support SAP ECC and S/4HANA integration with Vertex
• Perform end-to-end testing from SAP sales order through billing and Vertex tax calculation

Preferred Qualifications

• Vertex O Series implementation, upgrade, or migration experience
• Experience with Vertex Cloud
• Experience supporting multiple legal entities and complex tax jurisdictions
• Knowledge of tax exemptions, customer classifications, and product taxability
