Antithesis is seeking a Payroll & Accounts Payable Manager to own financial operations as the company scales. The role sits at the operational center of finance, requiring hands-on execution across payroll processing, accounts payable, expense management, and benefits administration.
Key responsibilities include processing payroll accurately and on time for a multi-state workforce, managing the full accounts payable cycle (invoice intake, approval routing, payment execution, reconciliation), administering employee expense reimbursement and corporate card programs, supporting benefits administration in coordination with HR, maintaining payroll records for audit and tax purposes, and staying current on state and local payroll tax compliance as the company expands into new jurisdictions. You'll also identify and drive improvements to payroll and AP systems and workflows.
The ideal candidate brings 3+ years of payroll and accounts payable experience, preferably at a tech or growth-stage company. Proficiency with payroll platforms (Rippling, Gusto, ADP, or similar) and accounting systems (NetSuite preferred) is required. You should have working knowledge of multi-state payroll tax requirements, a high bar for accuracy, and the ability to handle confidential information with discretion. The role demands strong organizational skills, deadline-driven execution, and a process-oriented mindset focused on continuous improvement.
Antithesis is a well-funded, deeply technical company headquartered in Northern Virginia with satellite offices in London and San Francisco. The team works in the office daily in Vienna, VA, collaborating closely to tackle hard problems in software reliability and verification.
