• You are comfortable modelling systems, integrations and processes using UML and BPMN.
• You have experience working with Enterprise Architect or a similar tool for system modelling and documentation management.
• You understand dependencies between systems and can assess the impact of changes on functionalities, integrations and data.
• You can present and justify your proposed solution when working with developers, QA engineers and architects.

• Experience analysing non‑functional requirements and supporting the team throughout implementation and testing.

• Use SQL to analyse data, validate system logic and diagnose inconsistencies.
• Prepare system models, diagrams and documentation that provide a basis for discussions with developers, QA engineers and architects.
• Consult proposed solutions with the technical team and incorporate architectural decisions and implementation constraints into the final design.
