Are you excited about building the future of digital lending at massive scale? Do you want to design and build systems that power credit experiences for millions of customers in one of the world's largest and fastest-growing fintech markets?

The Credit & Lending team at Amazon Pay is building Amazon's next-generation lending platform to enable seamless credit experiences for millions of customers across Latin America. We are looking for a strong Software Development Engineer to join our Brazil engineering team and build highly scalable, resilient lending systems from the ground up.

This is a greenfield opportunity. You'll design and deliver critical components of the lending platform including underwriting, loan servicing, repayments, regulatory reporting, and customer-facing experiences. You'll work with latest fintech challenges: real-time decisioning, payment orchestration, compliance automation, and financial data integrity at scale.

This role is ideal for an engineer who wants deep ownership, loves solving hard technical problems, and is energized by the ambiguity and pace of building something new in a regulated, high-stakes domain.

What You'll Do
Design and build core services for the 1P Lending platform in Brazil—spanning underwriting, servicing, repayments, accounting, and compliance.
Write high-quality, production-ready code for backend and Frontend services, with a focus on reliability, testability, and operational excellence.
Own system architecture decisions for your area—API design, data modeling, event-driven flows, and integration patterns with internal and external partners.
Build for compliance—implement systems that meet Brazilian financial regulations (Central Bank reporting, PIX, Open Finance) with auditability and data integrity baked in.
Operate what you build—own monitoring, alarming, on-call, and incident response for your services. Drive high availability and low-latency targets.
Solve ambiguous problems—break down complex business and regulatory requirements into clean, extensible technical solutions.
Collaborate cross-functionally—work closely with product, finance, tax, risk, legal, and partner integration teams to translate requirements into working systems.
Contribute to platform reuse—build shared libraries, frameworks, and architectural patterns that enable scaling across LATAM markets.
Raise the bar—participate actively in code reviews, design reviews, and hiring. Mentor junior engineers and contribute to team culture.

Influence the broader platform by contributing reusable components, shared libraries, and cross-market architectural patterns.
