• Support audits, reporting, tax filings, and multi-state compliance
• Partner with HR, Accounting, and IT to streamline and modernize workflows

• Bring new ideas, help us automate, and champion continuous improvement
Requirements
What You Bring
• 2+ years of payroll experience (multi-state strongly preferred)
• Strong understanding of payroll laws, taxes, and compliance requirements
• Proficiency with Excel and experience with HRIS/payroll systems (ADP, UKG, Workday, Paycor, etc.)
• Analytical mindset — comfortable with data, reconciliations, and problem-solving
• Organized, detail-focused, and energized by improving manual processes
• A collaborative communicator who likes partnering across teams
Benefits
Why You’ll Love Working Here
• You’ll play a big role in modernizing our payroll and HRIS foundation
