About the Role: 

We are looking for a hands-on engineer who enjoys writing code, solving complex backend problems, and building reliable payment systems. The ideal candidate takes ownership from development to production, is comfortable debugging real-world issues, and can turn business requirements into robust technical solutions.

• Implement and optimize payment processing capabilities, including payment initiation, transaction status management, reconciliation, and exception handling.

• Integrate with Brazilian banks, payment service providers, and external financial systems through APIs and other integration mechanisms.

• Build reliable, high-performance backend systems with a strong focus on transaction consistency, idempotency, fault tolerance, and system availability.

• Troubleshoot production issues, identify root causes, and implement effective solutions to improve system stability and performance.

• Monitor system performance, identify bottlenecks, and continuously improve the reliability, scalability, and efficiency of payment services.

• Support payment-related security, risk control, and compliance requirements in collaboration with relevant stakeholders.

What We're Looking For:

• Strong hands-on backend development experience with Java and PIX, preferably using Spring Boot and related frameworks.

• Experience with PIX, Brazilian payment systems, or integrations with Brazilian banks and local payment service providers.

• Solid understanding of RESTful APIs, microservices architecture, distributed systems, and database design.

• Experience working with relational databases and SQL; familiarity with caching, messaging systems, and asynchronous processing is a plus.
