  • Comfortable handling employee relations and sensitive conversations with professionalism.
  • Confident with common tools (email, spreadsheets, payroll system, accounting software/QB).

Strong plus:

  • Family-owned or privately held company experience.
  • Experience improving processes, not just maintaining them.
  • QuickBooks or similar accounting systems experience.


Schedule and environment:
