Quality & Testing: Write "test-first" code (JUnit/Mockito) and contribute to automated CI/CD pipelines to ensure 100% confidence in every deployment.
Experience you’ll bring

Java Specialist: Deep hands-on experience with Java and the Spring Ecosystem (Spring Boot, Spring Data, Spring Security).
API Design: Proven ability to build and scale RESTful services. Familiarity with GraphQL or gRPC is a plus.
Cloud & Databases: Experience working with AWS (Lambda, EC2, RDS) and proficiency in SQL (PostgreSQL) and NoSQL.
Message Brokers: Practical experience with asynchronous messaging like Kafka or RabbitMQ.
Modern Tooling: Comfort with Docker, Kubernetes, Git, and Maven/Gradle.
Problem Solver: Ability to debug complex issues across distributed systems and a passion for refactoring legacy code into clean, modular patterns.
