Your responsibilities will include:

• Gathering, challenging, and formalising business requirements with a strong focus on solution design
• Defining functional and technical specifications, with an emphasis on architecture impacts and end-to-end consistency
• Contributing to the definition of target solutions, application flows, interfaces, and data impacts
• Assessing the impact of new requirements on the existing application landscape, particularly Cobol and Java components
• Working closely with development teams in Portugal and other stakeholders to ensure robust and scalable designs
• Supporting testing phases, including integration testing and UAT, and helping resolve defects from a design perspective
• Contributing to continuous improvement, simplification, and optimisation of business and application processes
