• Act as the day-to-day decision maker for A/P operations, resolving escalations and mitigating financial and operational risks.

• Design and improve A/P processes, controls, and policies to enhance efficiency, reduce risks, and ensure audit readiness.

• Drive improvements in cash management (e.g., DPO, payment timing) while maintaining strong vendor relationships.

• Partner with IT and Finance to automate A/P workflows (e.g., OCR, AI-driven coding, electronic payments) and reduce manual work.

• Support month-end close activities, including A/P reconciliations, accruals, and variance analysis.

• Build and track A/P performance metrics (e.g., DPO, aging reports, discount capture) and provide visibility to leadership.

What We're Looking For

• At least 8+ years of AP experience, including in a fast-paced scaling environment.

• 2+ years in a managerial role overseeing AP teams.

• Deep expertise in AP processes, controls, accounting (OPEX/CAPEX), vendor management, and payment processing.

• Strong operational mindset to prioritize, troubleshoot, and execute under tight deadlines.

• Strong leadership skills to mentor teams, drive process improvements, and collaborate with stakeholders.

• Good Excel skills and experience with ERP systems (SAP S/4HANA preferred).
