About the role

Rebill is a financial infrastructure platform for the Americas, used by companies in software, AI, travel and digital services across Brazil, Mexico, Argentina, Colombia, Chile and the United States.

The company needs one person who owns the financial operation end to end and understands how a payments business makes and loses money.

Key responsibilities

• Pricing and commercial margin: build and maintain the cost model behind every deal (processing, FX spread, installments, taxes, settlement), review pricing before it goes to a merchant and track realized margin by merchant and country
• Cost control: reconcile processing and FX costs against provider billing each month and explain variances
• Monthly close: make the existing agent closes faster and more accurate by reviewing outputs, fixing rules and code, and cutting close days and manual exceptions; work in Python on the pipeline that runs it
• Procurement: design and run the process from request to payment, including approvals, vendor onboarding, payment calendar and execution across entities and currencies
• Accounting firms: manage them as critical vendors, covering deliverables, deadlines, quality, cost and tax obligations in each country
