4. Systems, Integrations & Finance (Workday - SAP - GL) Own the payroll view of key integrations and interfaces, ensuring HR, T&A, payroll, banking and middleware feeds are accurate, approved and ready. Ensure Workday remains the source of truth across the TSA bridge and that people-data integrations reconcile cleanly to the payroll engine.
