• Systems Implementation and Process Improvement : Lead the payroll workstream for the transition to the new payroll platform, including requirements definition, configuration support, testing, data validation, and go-live readiness. Continuously assess and improve payroll processes, integrations with ERP / HRIS and timekeeping systems, and documentation to drive efficiency, accuracy, and auditability.
• Time & Attendance, T&E, and Expense Management : Own the operational processes for time and attendance capture, expense report review, and T&E policy enforcement.

• Payroll Accounting, Reporting, and Reconciliation : Collaborate with the Accounting team to prepare and review payroll-related journal entries, account reconciliations, and variance analyses (wages, taxes, benefits, bonuses, and accruals). Provide routine and ad hoc payroll reports and analytics to Finance, HR, and leadership, including headcount, labor costs, overtime trends, and other key metrics.
• Vendor and Stakeholder Management : Serve as the primary point of contact for external payroll, tax filing, and T&E vendors.
