Your responsibilities

About the project
We are looking for an experienced Senior System & Integration Analyst to join a long-term project within a large international organization from the financial sector.
The role combines system analysis, requirements engineering and integration design. You will act as a bridge between business and technical teams, translating business needs into clear technical requirements, integration designs, API specifications and data models.
This is an analytical and design-focused position rather than a software development role. Strong hands-on experience with REST API design and UML is particularly important.
