As part of a collaborative, cross-functional team, you will work closely with Software Engineers, Technical Leads, Product Owners, Quality Assurance Engineers, and Architects to design, implement, test, and maintain robust backend solutions. You will also have the opportunity to contribute to engineering best practices, CI/CD improvements, and the adoption of AI-assisted development tools throughout the development lifecycle.

Core skills you’ll bring

  • 4+ years of experience developing backend applications with Java.

  • Strong knowledge of Java 11+ (Java 17/21 is highly valued).

  • Hands-on experience with Spring Boot and REST API development.

  • Experience with testing frameworks such as JUnit and Mockito.

  • Understanding of CI/CD practices, Git, Maven, and Docker.

  • Experience working with asynchronous processing and event-driven architectures.

  • Ability to work autonomously and contribute to technical discussions and code reviews.

Nice-to-have

  • Experience with Apache Kafka and messaging-based architectures.

  • Knowledge of MongoDB or other NoSQL databases.

  • Experience with Spring Security and JWT-based authentication.

  • Understanding of Hexagonal Architecture and SOLID principles.

  • Experience in Banking, Fintech, Payments, or other regulated industries.

  • Knowledge of Resilience4j, SonarQube, Testcontainers, or similar engineering tools.

  • Experience using AI-assisted development tools such as GitHub Copilot, Cursor, or ChatGPT.

  • Exposure to Java 21 features and modernization initiatives.

The impact you'll create

  • Develop and maintain scalable backend services that support critical banking products and operations.

  • Contribute to the modernization of legacy systems and the adoption of modern Java development practices.

  • Ensure software quality through automated testing, code reviews, and engineering best practices.

  • Collaborate with cross-functional teams to deliver secure, reliable, and high-performing solutions.

  • Participate in the evolution of CI/CD processes and software delivery standards.

  • Help drive innovation through the responsible adoption of AI-powered development tools and modern engineering practices.
