About the Role

We are hiring a part-time Payroll & HR Admin to keep our internal admin work accurate and on schedule. This is not a full-time HR department role. Most of the work is cyclical. You will help with payroll, contractor payment summaries, onboarding and offboarding, workers comp records, insurance updates, state registrations, company mail, and internal SOPs. The right person is organized, careful with numbers, and comfortable working independently in a remote company. You should be able to prepare clean information, follow deadlines, and flag issues, but you will not be expected to make legal, tax, or senior HR decisions on your own.

Responsibilities

  • Run the biweekly payroll checklist, including commission inputs.
  • Reconcile Hubstaff time records against payroll records for workers comp accuracy.
  • Prepare Wise and Payoneer contractor payment summaries when needed.
  • Coordinate with the owner, Director of Operations, and accountant when payroll is ready to run.
  • Enter payroll data into The Hartford or similar insurance platforms for reporting.
  • Support the annual workers comp audit.
  • Handle employee and contractor onboarding and offboarding paperwork.
  • Coordinate basic system access changes during onboarding and offboarding.
  • Open state tax accounts and Secretary of State registrations when we hire in a new state.
  • Close state accounts when we no longer have employees in a state.
  • Manage PTO requests and approvals.
  • Maintain and update internal SOPs.
  • Handle incoming company mail.

Requirements

  • Experience supporting payroll for a small company, ideally under 50 employees.
  • Comfortable with payroll records, timekeeping records, and basic insurance reporting.
  • Comfortable preparing payroll inputs in a system such as Gusto.
  • Able to reconcile hours, rates, payroll inputs, and contractor payment records.
  • Some familiarity with state employer registrations, tax accounts, or Secretary of State filings.
  • Able to follow deadlines without daily management.
  • Organized, accurate, and responsive in a fully remote environment.
  • Comfortable handling confidential employee, contractor, payroll, HR, and payment information.
  • Comfortable using AI tools to draft SOPs, research admin questions, and organize information, with human verification before relying on the output.
  • Reliable internet and a quiet workspace.
  • U.S.-based and available during U.S. business hours around payroll and payment deadlines.

Nice to Have

  • Direct experience with Gusto.
  • Experience with The Hartford or a similar workers comp or insurance platform.
  • Experience with Hubstaff or another time-tracking tool.
  • Experience with Wise or Payoneer contractor payments.
  • Experience supporting a remote company.
  • Basic familiarity with multi-state employment administration.
  • Prior small-business HR, bookkeeping, or office admin support experience.

Benefits

Remote, part-time work with flexible scheduling around payroll deadlines
Small-team environment with clear recurring responsibilities
5-10 hours per week; some payroll weeks are heavier than others
Tools include Gusto, Wise, Payoneer, Slack, ClickUp, HubStaff, Google Workspace, and The Hartford or similar insurance portals
