You will own the accounting side of equity plan administration and payroll accounting—two areas most companies split across departments. This is a hands-on role requiring someone who understands both the equity and payroll sides: how a stock option exercise becomes taxable income in payroll, and how a payroll register becomes a journal entry that ties out.
Equity Administration:
- Run the equity grant process end-to-end in Carta: intake from HRIS and offer letters, draft grants, support board consent routing with outside counsel, and confirm acceptance and recordkeeping
- Process exercises, terminations, and cancellations, including vested and unvested calculations and post-termination exercise windows
- Own recurring equity reconciliation across HRIS, Carta, and source documents; drive exceptions to resolution
- Bridge equity taxable events into payroll: compute imputed income and withholding for exercises, vests, and dispositions; ensure they flow into payroll and W-2 correctly
Payroll and Benefits Accounting:
- Own GL posting of every payroll: prepare journal entries from payroll registers, maintain account mapping, and tie posted entries back to source reports
- Prepare monthly reconciliations of payroll balance sheet accounts: clearing, employee receivables, benefit withholdings, accrued payroll, and payroll tax liabilities
- Reconcile benefits monthly: carrier invoices to enrollment to employee deductions; clear aged balances in benefit-related accounts
- Maintain the month-end wage accrual and reversal process
You will be the person who ensures the cap table, payroll system, and general ledger all agree, bringing analyst-level review to reconciliations that support month-end close and audit readiness.
