We are looking for a Backend & Integration Java Developer to maintain and evolve a core enterprise application. You will work in a diverse environment, managing integrations with other systems and contributing to the modernization of the platform.
Main Responsibilities
Maintain, debug, and improve existing backend services built mainly with Java (1.7/1.8), Spring Boot and some legacy components (EJB, Swing).
Contribute to building and monitoring reliable integrations using tools such as WebMethods, IBM MQ and SFTP file transfers.
Design and consume REST and Web APIs to connect different functional domains.
Work with Oracle 19c databases on Unix environments, focusing on queries and data‑related performance.
Take part in the gradual modernization of the platform, including moving legacy parts towards microservices and containerized environments.
Use AI‑assisted development tools (e.g., GitHub Copilot, ChatGPT/Claude) in your daily work to speed up coding and debugging, while keeping a strong focus on code quality and security.
Collaborate with Business Analysts, internal teams and external hosting partners (e.g., DXC) to align on technical specifications and releases.
