About Rebill

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, general 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.

We are AI-native by design. You will push engineering beyond AI-assisted coding into agentic workflows: autonomous coding and review agents, evals, feedback loops, human-in-the-loop controls, observability, and guardrails that let us safely automate more of the SDLC and production operations. The goal is not to use AI more; it is to rethink how a small engineering team can build and operate financial infrastructure.

You will hire and co-lead a small, high-caliber in-house engineering team alo
