Senior Manager, Accounts Payable - Compute

The posting, as OpenAI wrote it

About the Team

OpenAI’s Procurement team makes working with the world easy, fast, and safe. We connect supplier readiness, purchasing, invoicing, and payment so teams can move with confidence as OpenAI scales. Accounts Payable and Supplier Master Data Operations provide the trusted data, dependable execution, and financial discipline behind that experience.

About the Role

OpenAI’s compute infrastructure depends on controlled execution of significant supplier spend. As Senior Manager, Accounts Payable — Compute, you will own payment readiness and material exceptions across large-value, business-critical obligations. Complex agreements evolve through amendments to pricing, capacity, service credits, billing mechanics, legal entities, and payment schedules. You will translate approved obligations into accurate, timely payments while navigating supplier disputes, late approvals, close deadlines, and cross-system dependencies.

We’re looking for a hands-on technical and operational leader who can interpret complex payment terms, reconcile financial data, diagnose system failures, and build scalable workflows. Coordinating across multiple Compute Finance and Accounting teams is a core responsibility: you will establish decision owners, align deadlines, and move interdependent work forward in parallel. You will set the compute AP operating plan and lead delivery with Procurement, Treasury, Tax, Finance Systems, and existing processing teams, with measurable improvements in controls, service, and capacity.

Location: This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will

• Own the compute invoice-to-payment operating plan, prioritize material exceptions, and lead supplier escalations across complex, high-value obligations and tight payment deadlines.
• Interpret executed contracts and approved amendments affecting pricing, capacity, credits, billing mechanics, entities, and payment schedules; translate them into invoice-validation, PO/change-order, approval, control, and payment requirements.
• Personally investigate discrepancies, supplier disputes, missing credits, duplicate risks, and PO coverage gaps. Trace records, field mappings, approval statuses, and sync failures across procurement and ERP systems; resolve root causes with accountable Finance, Procurement, supplier, and Systems partners.
• Lead a payment-readiness cadence across Compute Finance and Accounting teams, consolidate the complete obligation and payment view, and resolve dependencies across charge validation, PO coverage, approvals, funding, and close. Track decision owners, deadlines, blockers, and escalation paths so material payments move forward as approval lands.
• Confirm supplier, site, entity, tax, payment-method, and approval readiness with the relevant owners before payment release.
• Coordinate funding forecasts and close-period payment
