• Serve as a tier-2 escalation point for employee payroll inquiries, resolving issues with speed and professionalism.

• Monitor regulatory changes in federal, state/provincial, and local tax law and proactively flag impacts to the team.

• Contribute to the buildout of payroll infrastructure to support international expansion beyond the US and Canada.
