Global HRIS Payroll Manager — Walmart @ Walmart
About
Enterprise payroll does not fail because of processing. It fails because of architecture, controls, and ownership. I lead SAP payroll environments across ECC and S/4HANA with a focus on stabilization, governance, and financial integrity within complex enterprise HR systems. My experience spans large-scale U.S. and Canadian payroll operations where payroll intersects directly with finance, compliance, workforce systems, and enterprise risk. I have served as the functional authority within complex SAP ecosystems alongside major implementation partners, supporting post-go-live stabilization, upgrade cycles, production issue resolution, and cross-system integration alignment. My work frequently sits at the intersection of payroll, HR systems, finance, and operational governance — including environments utilizing SAP Payroll Control Center to strengthen monitoring, validation, and payroll process discipline. I also deliver end-user training to strengthen operational discipline across payroll teams and leadership. My focus is consistent: contain risk, protect financial accuracy, and ensure payroll operates as a controlled enterprise function — not a downstream processing task.
