Payroll & Equity Adminstrator

Base Power Company • Austin, TX

10d • Onsite

About The Position

Base is America’s next-generation power company, focused on deploying distributed batteries to create a resilient and abundant electricity system. This role is responsible for fully owning and directly managing the payroll and equity administration processes for a growing, fully in-person team. The position involves processing payroll cycles, ensuring proper integration of payroll journal entries and departmental allocations, and administering the company's equity program from grants to cap table hygiene. The role will also support the transition to a new equity administration platform and manage the accounting for stock-based compensation. Collaboration will be key, working closely with the accounting team, People team, and Finance office.

Requirements

• 3–6+ years in payroll and/or equity administration, ideally both, at a high-growth company.
• Hands-on experience processing payroll end to end, including journal entries and allocations.
• Experience administering an equity program: grants, vesting schedules, exercises, and cap table reconciliation.
• Working knowledge of stock-based compensation accounting, including ASC 718 concepts and early exercise treatment.
• High attention to detail.
• Discretion. You'll regularly handle sensitive compensation and ownership data.

Nice To Haves

• Experience with an equity platform migration (e.g., Carta, Shareworks) is a strong plus.

Responsibilities

• 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.
