About Rebill

Rebill is a YC-backed payments company processing across six markets in Latin America and the United States. We process payments for merchants in Argentina, Brazil, Colombia, Mexico and Chile, and settle cross-border out of the region. Each market has its own entity, its own acquirers and partners, and its own regulator. The regional operations center is in Uruguay.

Our merchant base is a mix. The core is international: companies in the United States, Europe and Asia selling into the region in online education, SaaS, insurance and travel assistance. We also process for local merchants in several markets. Cross-border settlement, intercompany flows and multi-jurisdiction tax obligations are daily realities, not edge cases.

The founding team has deep payments experience and all of us are builders. You would be joining early, with direct access to the founders and real influence over how the company scales.

About the role

Today, tax across the group is managed by the founders with support from local accounting & tax firms. That has worked for the current scale, but it requires the best talent to keep growing as the company processes in six countries with intercompany flows, cross-border settlement and corporate matters. This role takes ownership of the tax function and builds it into something that holds up to the scrutiny of investors, auditors and regulators across every market.

The profile we need is a manager, not a pure technician. You will coordinate external tax advisors in each jurisdiction, set priorities, define what questions to ask, and make sure what comes back is operationally useful. For deep local technical work, there will be specialists. Your job is to see the full picture, identify the risks, and structure solutions across the group.

At Rebill everyone uses AI tools as part of their daily work, not only to write but to analyze data, model scenarios and move faster. We expect the same from you.

Why this role exists

Rebill operates through separate legal entities in Argentina, Brazil, Colombia, Uruguay and the United States. Revenue flows across borders, settlement involves currency conversion, and the intercompany structure needs to be part of the company strategy.

Getting this right determines how much of the revenue we keep, always in a way that our positions in each country are compliant and avoiding contingencies, and whether the corporate structure supports growth or creates friction. Tax is not a back-office function here. It is a commercial decision that affects pricing, market entry and capital efficiency.

What you will own

Intercompany structure. The contracts, invoicing flows and transfer pricing documentation between every entity in the group. Today this is documented, but there is room to strengthen our tax position. You build it: who invoices whom, for what services, at what price, with what evidence. The structure needs to be compliant in front of DIAN, AFIP, Receita Federal and the IRS.

Transfer pricing. Design and maintain the transfer pricing model for the group. Define the methodology, prepare the supporting documentation, and coordinate with external advisors in each country to ensure local compliance. This includes technology services, payment processing services, and any IP licensing arrangements.

Tax compliance across markets. Own the calendar and the quality of tax filings in every jurisdiction. You do not prepare every return yourself. You set the standard, review the work of local firms, catch errors before they become problems, and make sure nothing falls through the cracks.

Tax risk and planning. Identify exposure before it materializes. Withholding tax on cross-border payments, treaty applicability, establecimiento permanente risks, deductibility of intercompany charges, local vs. cross-border revenue recognition. Flag what matters, propose the fix, and execute.

Corporate restructuring support. You support the tax workstream: analyzing the implications in each jurisdiction, coordinating with legal and financial advisors, and ensuring the group structure is tax-efficient.

Zona franca compliance. The Uruguayan entity operates from Zonamerica. Free zone tax obligations, reporting requirements and the interaction between zone benefits and intercompany flows are part of your scope. You work closely with the Compliance Officer on the operational substance requirements.

Advisor coordination. External accounting and tax firms in each market report to you functionally on tax matters. You give them direction, review their output, and turn what they produce into decisions. Today that includes firms in Argentina, Brazil, Colombia and Uruguay.

What we are looking for

• A degree in accounting, tax or law, with a postgraduate specialization in taxation. An LL.M. or master's in international tax is a strong signal.

• 5+ years managing tax in a multi-country environment, ideally in payments, fintech, or financial services. You have dealt with cross-border flows, not just domestic filings.

• Direct experience building or managing intercompany structures and transfer pricing documentation. You have been through an audit or a review where this was tested.

• Working knowledge of at least three Latin American tax regimes. You do not need all six. You do need to know what questions to ask in the ones you have not worked in.

• Experience coordinating external tax advisors across jurisdictions. You know the difference between receiving an opinion and turning it into an operational decision.

• Comfort with the numbers. You can read a P&L, reconcile a withholding, and spot when a local entity is showing profit it should not have, or losses that do not make sense.

• Professional English. Our investors, banks and partners are international.

• Based in Uruguay or ready to relocate, and able to work from our Zonamerica office.

• AI tools as a working habit. Everyone at Rebill uses them daily.

Nice to have

• Experience in a payments company or PSP, where tax intersects with acquiring, settlement, FX and cross-border flows.

• Brazilian tax experience. Brazil is our most complex market, with specific challenges.

• US tax exposure: Delaware corporate structures, QSBS, 409A valuations, or working with US-based advisors on international structures.

• Knowledge of the Uruguayan free zone tax regime and its interaction with transfer pricing.

• Experience supporting a corporate restructuring, a flip or a fundraising round from the tax side.

• Portuguese.

• Participation in professional associations such as IFA, ICDT or equivalent.

Work arrangement

• Hybrid work model

• Monday to Friday, from 9:00 AM to 6:00 PM
