Team Leadership: Manage and mentor a small team of AP associates. You’ll provide guidance, prioritization support, and performance feedback.

Identify and mitigate fraud risk in payment workflows. Month-End Close Support: Own AP close activities including accruals, vendor statement reconciliations, and aged payables review. Ensure completeness and accuracy of AP balances across all entities for month-end reporting. Systems & Process Improvement: Optimize AP workflows in NetSuite and Zip, identifying automation opportunities to reduce manual effort and improve accuracy. Lead or contribute to system implementations or upgrades as the company scales. Global AP Operations: Support AP processes across US and international entities (UK, Ireland, Poland, Germany), including multi-currency payments, VAT considerations, and compliance with local payment practices. Audit & Compliance Readiness: Maintain audit-ready AP documentation, support external auditors with AP-related requests, and contribute to the development of internal controls aligned with SOX or equivalent frameworks. Cross-Functional Collaboration: Partner with FP&A on cash flow forecasting, with Legal on contract and vendor onboarding requirements, and with business stakeholders to ensure spend is appropriately budgeted and coded. We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection.
