Collaborate with product, QA and DevOps to ship features via CI/CD pipelines, containerization (Docker) and orchestration (Kubernetes).
Troubleshoot production issues, profile performance bottlenecks, and implement monitoring/alerting to ensure service reliability.

Experience with build tools and source control: Maven/Gradle and Git; CI/CD pipeline exposure.
Test-driven development experience with JUnit and Mockito; familiarity with logging and observability (Prometheus, Grafana, ELK) is expected.

Preferred

Experience with cloud platforms (AWS) and deploying Java services to cloud infrastructure.
Familiarity with event-driven architectures and messaging platforms (Kafka, RabbitMQ).
Performance tuning, JVM profiling, and distributed tracing experience (Jaeger, Zipkin).
