About the Role

We’re looking for a motivated Junior Software Engineer eager to build reliable, scalable applications while growing within a collaborative engineering team.

In this role, you will contribute to the development of backend features, event-driven microservices, and modern user interfaces. You will work alongside experienced engineers and gain hands-on experience building production-ready software using modern technologies.

Your Role

• Event-Driven Systems Development
  Participate in designing and developing scalable event-driven microservices using Java, Spring Boot, Spring Cloud, and Apache Kafka, ensuring reliability and real-time data flow across services.
• Kafka Streams Optimization
  Contribute to Kafka Streams applications that process and aggregate large-scale data efficiently. Implement serialization and deserialization strategies using Avro, JSON, and Protobuf, while helping maintain schema compatibility through Schema Registry.
• Frontend Development
  Collaborate with the frontend team to build and maintain responsive, intuitive user interfaces using React and React Native. Ensure seamless integration between frontend applications and backend microservices.
• Code Quality Improvement
  Improve code maintainability, performance, and security. Use SonarQube and SonarLint to conduct static code analysis and ensure that Kafka-based microservices follow established quality standards.
• Automated Testing Strategies
  Contribute to the design and implementation of automated tests using JUnit, Mockito, and Testcontainers, ensuring the reliability and correctness of Kafka message producers and consumers.
• Contract and Integration Testing
  Help implement Kafka integration and contract tests to validate message schemas and ensure consistent, reliable communication between microservices.
• Caching and Performance Optimization
  Use Redis and intelligent caching strategies to improve application throughput and reduce latency in message-driven workflows.

Responsibilities

• Participate in the design and development of backend features in collaboration with senior engineers and frontend developers.
• Contribute to event-driven microservices using Java, Spring Boot, Spring Cloud, and Apache Kafka.
