Responsibilities include creating RESTful APIs, integrating external systems via SOAP/REST web services and messaging platforms, and using AI tools to accelerate development-including code generation, code transformation, automated unit test creation, security vulnerability detection, and intelligent suggestions within IDEs. Additional duties include conducting unit and automated testing, supporting data migration to relational databases (DB2, PostgreSQL, Oracle), and contributing to CI/CD pipeline development.
The Lead Full Stack Java Developer will have strong experience in Java full-stack development, Spring Framework, and RESTful API design, combined with front-end proficiency in JavaScript, HTML5, CSS, and Bootstrap.
