THE ROLE The Interim Payroll & Benefits Supervisor/Manager leads day-to-day payroll operations for a multi-state workforce of roughly 1,600 employees, combining hourly and salaried populations across headquarters and fulfillment centers on the East and West Coast, while covering a planned leave. Payroll is the core of the role. The role carries heavy reporting and Accounting audit work, and prepares payroll for year-end and the Dayforce-to-Workday transition. The position also handles a defined set of benefits administration tasks and owns payroll-related Workday configuration, in partnership with Program Management. Thrive Market operates in a growth-stage environment where payroll and Workday processes are still being built out, so this role is hands-on: it runs payroll and also helps build, document and improve the payroll and Workday foundation.
