• Create integrations with SAP Commerce, SAP ERPs, API Gateway, and other enterprise systems.

• Implement authentication and authorization in backend services using Spring Security (including OAuth2/OpenID Connect/Keycloak scenarios).

• Ensure automated testing (unit and integration tests, including the use of Testcontainers with databases).

• Work alongside system frontend, SAP teams, UX/UI, and business teams in an agile environment (Scrum/Kanban), participating in refinements, planning, and reviews.

• Contribute to code reviews, technical documentation (in both Portuguese and English), and knowledge transfer to the team.

⛳️ Requirements

• Over 5 years of experience with Java in corporate web applications.

• Extensive experience with Spring Boot and the Spring ecosystem (Web, Data, Validation, Actuator, and Spring Security).

• Familiarity with REST APIs (resource modeling, pagination, error handling, versioning).

• Experience with microservices architecture: domain-based independent services; synchronous communication (REST) and, preferably, asynchronous communication (messaging/events).

• Proficiency with databases: Relational (preferably PostgreSQL — modeling, indexes, queries); Non-relational (preferably MongoDB).
