Job Requirements

Strong grounding in OOP principles and design patterns(Visitor,Strategy,Adapter,Decorator,Facade).Comfortable applying tree traversal algorithms and dynamic programming; forward/backward chaining and branch-and-bound are a plus.

Spring ecosystem (Framework,Boot,Integration),OpenFeign,Jackson Core/DataBind,with document-processing libraries(PDFBox,Apache POI),Docker/AWS S3/GCP Storage for deployment and storage. Experience with Aspose.Words,search/NLP libraries(Apache Lucene, Stanford CoreNLP),messaging systems(Kafka,Artemis JMS/Tibco EMS),native interop via JNI (FontConfig,FreeType,HarfBuzz,Graphite2,TECKit) is a plus.

Gradle 8 build pipelines,GitHub Actions CI,testing with JUnit 5 and Mockito are core to the role.Familiarity with static analysis(Checkstyle,Spotbugs, XMLUnit),observability tooling(Prometheus,Grafana,Kibana/ELK Stack) is a plus.
