• 5+ years of payroll experience, including managing payroll across multiple entities and countries.

• Strong knowledge of payroll processes, compliance, and vendor management.

• Experience with global payroll systems (Deel, ADP, Workday, or similar).

• Demonstrated ability to validate payroll runs, identify discrepancies, and resolve issues.

• Experience with contractor payments and associated compliance.

• Strong Excel/Google Sheets skills; ability to build payroll trend reports.
