We are currently searching for a Java Developer Sr:
Responsibilities
- Develop domain-focused Java microservices (Spring Boot) with clear endpoints, robust validations, and maintainable internal structures, strictly adhering to clean design principles and separation of concerns.
- Implement read models and projections using the CQRS pattern: design collections/documents in MongoDB, define indexes, and build hydration components that keep the read state consistent with business rules.
- Consume and publish events using Apache Kafka (Spring Kafka): implement robust, idempotent consumers, manage logical retries and errors, and ensure contract compatibility within the event-driven ecosystem (utilizing Schema Registry).
- Optimize query performance: analyze access patterns, tune MongoDB aggregations, pagination, and filters, and refine data models to minimize latency and load on consuming services.
- Collaborate extensively with BFF (Backend-for-Frontend), Frontend, and Data Plane teams to agree on API contracts, required fields, and semantics.
- Document APIs using OpenAPI/Swagger and ensure all changes are backward-compatible and progressive.
- Ensure code quality through rigorous testing using JUnit and Mockito.
Requirements
- Strong hands-on experience with Java: Deep proficiency in Java 17+, encompassing modern features and functional paradigms.
- Expertise in the Spring Ecosystem: Extensive experience with Spring Boot, Spring Web, and Spring Data MongoDB.
- Database & Architecture: Proven experience with MongoDB (data modeling, indexing, aggregations) and practical implementation of CQRS and read models.
- Event-Driven Messaging: Hands-on experience with Apache Kafka (Spring Kafka) for event consumption/publication and familiarity with Schema Registry.
- Testing & Documentation: Strong proficiency in unit and integration testing using JUnit and Mockito, and API documentation using OpenAPI/Swagger.
- Build Tools: Experience with Maven or Gradle.
- Banking Sector Experience: 3+ years of experience working within the banking or financial services industry, understanding its rigorous standards for security and transactional integrity.
- High-Performance Mindset: Resilience, emotional intelligence, and a focus on agile delivery.
- Technologist DNA: A deep understanding of the difference between "coding" and "engineering," specifically within distributed, event-driven architectures.
Desired
- Familiarity with frontend frameworks (like Angular) to effectively collaborate on BFF implementations.
- Experience with cloud platforms (AWS, Azure, or GCP) and containerization (Docker, Kubernetes).
- Familiarity with cloud-native foundations or AI coding assistants.
Languages
- Advanced Oral English.
- Advanced Spanish.
