  • Building and maintaining high-quality connections to banks’ APIs
  • Building strategies and solutions for value-added services and features
  • Combining tech features into products and services that solve client needs and are viable from a business perspective

You will be part of a 5 developers squad led by either a scrum master and a key developer. The squad structure is flat and T-Shaped, so it means that there is no hierarchy and every developer does all kinds of tasks. Your squad would be a part of the Connectivity Team that, as of now, includes 5 similar squads. The squad’s main responsibility would be to own and integrate the Iberian market. The squad will also contribute to the new features and capabilities design, building frameworks around API standard and internal tools extensions
