Job description

Rebill is the financial infrastructure platform for the Americas.

The companies shaping software, AI, travel, and digital services use Rebill to operate across Brazil, Mexico, Argentina, Colombia, Chile, and the United States.

Rebill brings local payments, installments, recurring billing, stablecoin rails, treasury, global payouts, and financial operations into one platform built for how money actually works across the Americas.

Every market is different. Rebill makes the infrastructure consistent. Engineering, finance, and operations teams can manage local currency acceptance, market-specific payment behavior, funds, and financial workflows from the same platform.

Companies can launch in Latin America in as little as a day and expand across markets without rebuilding their financial stack country by country.

Built locally. Designed to scale globally.

Rebill is backed by leading global investors such as Tiger Global, Y Combinator (W22), Soma Capital and SV Angel, and angels including Guillermo Rauch (Vercel) and Arash Ferdowsi (Dropbox).

About the role

You run engineering day to day: delivery, reliability, and the technical bar of everything we ship.

Rebill processes real money across six markets on its own infrastructure. Event-driven microservices on a message bus, Kubernetes across Azure and AWS, infrastructure as code, and smart routing across a different set of local acquirers in every country. Card data lives in an isolated, tokenized environment.

You lead a small in-house team alongside external engineering partners, and you report to the CTO, who owns architecture, security, and the technical relationship with our acquirers. You own everything between that and production.

This is a hands-on seat. You will review pull requests and write code in your first year. If you have not been close to a codebase in the last two years, this is not the right seat for you.

Why this role exists

Rebill launched its own payment infrastructure in September 2025, starting with Argentina. In one year it went from that single market to six.

That platform was built fast by very few people. The next stage is different: more volume, more acquirers, more markets, and merchants whose finance teams depend on us settling correctly every day. That needs someone whose full-time job is making the platform reliable, cheap to extend, and predictable to ship on.

What you will own

• Reliability. Uptime, incident response, observability, and the performance of payment routing. When approval rates drop in one market at two in the morning, you are the person who knows why.
• Delivery. The quarterly technical roadmap, release cadence, and the honesty of our dates. Engineering commitments that hold are worth more than ambitious ones that do not.
• Technical bar. Code review standards, testing, on-call, and documentation across a team that is part in-house and part external. Raising the floor is most of the job.
• Time to market. Today every new acquirer and every new payment method is its own integration project. Your job is to turn that into something closer to configuration, so opening a market takes weeks instead of quarters.
• Capacity decisions. What we build in-house, what we keep with partners, and what that costs. You bring the numbers and defend the call.

What we are looking for

• 8+ years building software, with at least 3 leading engineers directly.
• You come from payments: acquiring, processing, ledgers, reconciliation, or a fintech moving real transactional volume. Not a company that happened to charge cards.
• Hands-on. You still write and review code, and you are the person who goes into the incident, not the one who asks for the postmortem.
• You have worked with external engineering partners or agencies and can describe what you did to make that model work.
• Distributed systems in production: event-driven architectures, queues, Kubernetes, infrastructure as code.
• Fluent English and Spanish. Our acquirers, auditors, and merchants do not share one language.
• AI tools as part of how you work. Everyone at Rebill uses them daily to move faster.

Nice to have

• You were the first or second engineering leader somewhere and left a platform that ran without you.
• Experience with PCI DSS or an equivalent audit.
• Direct integrations with local acquirers in Latin America.
• Portuguese at a working level for Brazil.
• Prior startup or YC-company experience at a similar stage.

What we offer

• A senior package matching the seat: competitive base and meaningful equity.
• Direct access to the founders, with no layers in between.
• Ownership of a payments platform that is already in production across six markets, at the point where the decisions you make still shape it.

How we hire

An intro conversation, a technical session on a real problem from our platform, and a conversation with the founders. No take-home exercise that we would not pay for. We will tell you what is still open and what is held together with tape. We expect the same candour back.
