Base Power Payroll & Equity Administrator at Base Power responsible for processing payroll and administering the equity program end to end. This role includes managing payroll journal entries, equity grants, vesting, exercises, and leading the transition to a new equity administration platform.

Responsibilities

Base runs payroll for a growing, fully in-person team, and grants equity to employees who join. Both processes need someone who owns them fully and directly — not as a side responsibility bolted onto another role.
This role processes payroll every cycle, ensures the payroll journal entry integration is properly mapped, prepares the payroll departmental allocations that feed the books, and administers Base's equity program end to end: grants, vesting, exercises, and cap table hygiene. You'll also support the transition to a new equity administration platform and own the accounting for stock-based compensation.
You'll work closely with the broader accounting team on the entries that hit the books each period, with People on new hires, terminations, and comp changes, and with Finance office on equity grants and cap table questions.
Process payroll every cycle for Base's full employee population, including multi-state and hourly or field-team complexity.
Prepare payroll journal entries and departmental/cost-center allocations, and reconcile payroll to the general ledger each period.
Administer Base's equity program: process new grants, track vesting, process exercises, and keep the cap table and option ledger accurate.
Lead the transition from Base's current equity administration process to a new platform — data migration, testing, and employee-facing rollout.
Own stock-based compensation accounting: expense recognition, forfeitures, modifications, and the accounting treatment for early exercises.
Answer employee questions on pay, equity grants, and vesting with clear, accurate information.
Build the SOPs and controls around payroll and equity administration so both processes scale without added headcount.
What You'll Bring
3–6+ years in payroll and/or equity administration, ideally both, at a high-growth company.
