Software Development Engineer in Test (Swagger/Postman)

The goal of the project is to build one of the main components of a new ecosystem responsible for the debt management process. The component is divided into several bounded contexts, each corresponding to the common business needs of local client markets, while also making it part of the Core system. The project is being carried out using a Domain-Driven Design (DDD) approach and Agile methodology, working in a way similar to Kanban.

Currently, the implementation of selected contexts is underway, and in the coming months, the rollout of additional modules is planned. Development and testing teams collaborate with Product Owners responsible for the individual business areas. The project is a greenfield initiative, so until its production launch, no maintenance tasks are expected.
