externaljobboards
You're starting your career and want to work on systems that matter. This role lets you design and build backend applications for a major Brazilian financial institution serving global clients. You'll work on real infrastructure problems—scalability, resilience, performance—while working alongside experienced engineers at a company with 25+ years of engineering leadership.
Day to day, you'll develop Java applications using Spring Boot and Quarkus, build microservices, and work with AWS services like Lambda, SQS, SNS, and DynamoDB. You'll also contribute to observability practices, integrations with the Nasdaq Calypso ecosystem, and event-driven solutions. This is hands-on backend work that teaches you how enterprise systems actually work.
You're a good fit if you have Java fundamentals, some exposure to microservices or AWS, and you're curious about how distributed systems operate. A portfolio or side projects using Spring Boot, or experience with cloud platforms, strengthens your application. You don't need years of experience—you need the ability to learn fast and ship code.
