We are seeking a knowledgeable and detail-oriented Senior Payroll Specialist with strong experience in U.S. and international payroll processing, Workday Payroll, and complex tax compliance. This role is critical to ensure accurate and timely payroll execution across multiple countries, with a strong focus on tax filings, audits, and global statutory compliance.

The ideal candidate will demonstrate the ability to thrive in both large-scale and fast-growing startup environments, showing adaptability, ownership of end-to-end processes, and hands-on problem solving. Experience with OneSource Virtual (OSV) or a comparable third-party tax provider is strongly preferred.

• Bachelor’s degree in Accounting, Finance, or CPP certification required.
• 5–7+ years of payroll experience, including full-cycle payroll processing in both large corporate and startup settings.
• Proven expertise managing multi-country payrolls across North America, EMEA, and APAC.
• Minimum 5 years of hands-on Workday Payroll experience.
• Strong knowledge of U.S. and international payroll tax compliance and reporting.
• Experience with OneSource Virtual (OSV) or comparable tax vendors is highly preferred.
• Strong understanding of payroll accounting, tax reconciliations, and funding processes.
• Advanced Excel and data analysis skills, with the ability to manage large, complex data sets.
• Demonstrated ability to thrive independently in fast-paced, high-growth environments with competing priorities and tight deadlines.

What You’ll Do: 

• Direct, process, and review international payrolls (e.g., Canada, UK, EMEA, APAC) in partnership with in-country vendors and internal stakeholders, ensuring accuracy, timeliness, and statutory compliance.
• Serve as backup for U.S. payroll processing in Workday, maintaining compliance with federal, state, and local regulations.
• Ensure payroll adherence to local statutory regulations, including social insurance, tax withholding, and reporting requirements.
• Collaborate with OSV on U.S. tax filings, amendments, and the resolution of agency notices.
• Review, reconcile, and analyze payroll tax liabilities and funding across jurisdictions.
• Coordinate with international payroll vendors to validate inputs and ensure timely and accurate delivery of gross-to-net calculations, payments, and statutory reports.
• Manage quarter-end and year-end payroll close processes, including W-2s, T4s, P11Ds, PSA filings, and other statutory deliverables.
• Conduct system testing and support Workday configuration updates to meet evolving payroll and compliance needs.
• Maintain comprehensive documentation of payroll processes, statutory requirements, and audit trails for all payroll entities.
• Provide support during internal and external audits, responding to requests related to both U.S. and international payroll.
