Lead, structure, optimize, and scale Mistral AI's Accounts Payable function, ensuring timely, accurate, and compliant payment processes while driving operational excellence and developing strong vendor relationships.

As a key member of the Accounting team, you will oversee the A/P team, streamline processes, and collaborate closely with R2R Accounting, Procurement, Legal, and other stakeholders to support Mistral's rapid growth and scalability.

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

• Drive improvements in cash management (DPO, payment timing, etc.) 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.

Requirements:

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

• 4+ 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: you can prioritize, troubleshoot, and execute under tight deadlines.

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

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

• Fluency in French & English.
