About the Role
Java Platform Engineering-Senior Java Engineer/Developer
Key Responsibilities
Design and implement net-new Spring Boot microservices per approved OpenAPI 3.1 specifications —
each service independently deployable, fully tested, and integration-ready
Enhance and upgrade existing legacy Java services to Spring Boot 3.x / Spring Framework 6.1 baseline,
including javax.* → jakarta.* namespace migration
Write comprehensive unit and integration tests targeting ≥80% code coverage using JUnit 5 and Mockito
Participate actively in code reviews — both receiving and providing feedback to peers to maintain team-
wide quality standards
Confirm implementations align to OpenAPI 3.1 contract specifications before SIT handoff
Document non-standard patterns or legacy findings encountered during development and escalate to the
Tech Lead
Contribute to service retirement analysis when assigned — impact assessment, dependency mapping, and
decommission documentation
Deliver consistently to wave-level schedules, maintaining SIT-readiness at dev close for each delivery cycle
Required Qualifications
5+ years of professional Java development with hands-on Spring Boot microservices experience in
production environments
Strong working knowledge of Spring Boot 3.x, Spring Framework 6.1, and Java 17
Solid understanding of the jakarta.* namespace migration and Spring Boot 3.x upgrade patterns
Experience implementing REST APIs from OpenAPI / Swagger specifications in a contract-first workflow
Working experience with Apache Kafka and RabbitMQ — producing and consuming messages, configuring
topics/queues, and implementing event-driven patterns in Spring Boot applications
Solid SQL skills and hands-on experience with Oracle and PostgreSQL in a Spring Data / JPA context —
writing queries, mapping entities, and optimizing data access patterns
Practical knowledge of enterprise caching — Redis (cache-aside patterns, TTL management, distributed
invalidation) and Spring Cache abstraction (@Cacheable, @CacheEvict, @CachePut); understands when
to cache, what to evict, and how to avoid stale data issues
Strong understanding of Java multithreading and concurrent programming — comfortable using
ExecutorService, CompletableFuture, and synchronized constructs; able to write thread-safe code and
recognize common concurrency pitfalls
Proficient with JUnit 5, Mockito, and integration testing patterns for Spring Boot applications
Comfortable working in a structured offshore delivery model with code-review gates and defined
acceptance criteria
Preferred Qualifications
Experience with telecommunications backend systems — billing, payments, enrollment, or catalog service
domains
Exposure to AWS-hosted microservice environments (EKS, API Gateway, RDS / DynamoDB)
Familiarity with JSP and Spring MVC for frontend-adjacent service work
Prior experience delivering in SIT → TST → PROD gated pipeline programs
Experience with Spring Batch or batch job implementation patterns
