About the Role
As a Senior Java Developer, you will actively participate in Scrum team dynamics, implementing pre-analyzed developments and executing unit tests from the start of each user story. You will work in close collaboration with functional analysts and testers, ensuring anticipation, technical accuracy, quality focus, organizational flexibility, and strong inter-team communication.
As a senior consultant, you will also mentor junior colleagues and facilitate knowledge transfer within the team.
You will contribute to a strategic transformation project in which a monolithic application — including externally developed modules — is being rewritten into a microservices-based architecture. The application operates in a banking-like environment (payments, bills, refunds) and includes accounting functionalities.
You will be assigned to one of the priority domains:
Accounting management
Transaction & order management
Rules management
