C3 AI is seeking a detail-oriented and motivated Senior Accounting Operations Analyst to join our Finance team. You will be responsible for managing the full accounts payable cycle including invoice processing, vendor payments, and month-end close support. The ideal candidate brings 4–5 years of hands-on AP experience, proficiency in NetSuite and Coupa, a passion for process improvement, Agentic AI processes and automation, and the ability to thrive in a fast-paced, high-growth enterprise AI environment.

Please note that this position is full-time and located onsite at our Redwood City office.

Responsibilities: 

• Process and review high-volume vendor invoices end-to-end: receipt, coding, two-way PO matching, approval routing, and posting in NetSuite; manage the AP inbox and ensure all invoices are processed accurately and on time.
• Execute domestic and international payment runs (ACH, wire, check, virtual card); manage payment scheduling and coordinate with Treasury to optimize cash flow.
• Own vendor onboarding and maintenance including W-9/W-8 collection, banking detail verification, and vendor master data integrity in NetSuite and Coupa; serve as the primary point of contact for vendor inquiries and dispute resolution.
• Drive process improvement initiatives across the full procure-to-pay cycle: identify manual bottlenecks, champion automation opportunities in Coupa and NetSuite, and leverage C3 AI’s own AI tools (agentic AI, generative AI) to reduce invoice cycle times and exception rates.
• Support month-end and quarter-end close by preparing AP aging reports, accruals, prepaid amortization schedules, and balance sheet reconciliations; ensure accurate cut-off and timely reporting to the Controller.
• Maintain robust internal controls over AP, including SOX-compliant documentation, duplicate-payment detection, segregation of duties, and audit-ready transaction records; support Auditors and internal audit reviews.
• Collaborate cross-functionally with Procurement, Legal, and FP&A on PO compliance, budget coding accuracy, and supplier contract terms; surface data-driven insights on DPO, payment trends, and spend analytics.
