We are seeking an experienced Senior Java Developer to lead the modernization of our legacy monolithic architecture by decomposing SOAP-based services into stateless RESTful microservices.

About The Role
  • Transition our legacy SOAP-based services to RESTful, scalable microservices using Spring Boot, deployed in AWS via Docker and Kubernetes (or ECS).
  • Apply domain-driven design and stateless principles to migrate business functionality from the monolith to a modern architecture.
Key Responsibilities

  • Lead the decomposition of tightly coupled SOAP services into independently deployable microservices.
Microservices & Cloud Deployment
  • Develop and deploy containerized microservices using Docker and Kubernetes, or AWS ECS.
  • Implement cloud-native architecture patterns for high availability, fault tolerance, and scalability in AWS.
Testing & Quality
  • Write comprehensive integration, unit, and API tests using JUnit, Mockito, Postman, etc.
  • Debug REST-to-SOAP interactions to ensure seamless migration and data integrity.
Performance, Caching & DevOps
  • Optimize performance with caching solutions (e.g., Redis, Memcached).
  • Maintain stateless service architecture principles.
  • Contribute to observability with Prometheus, Grafana, and ELK Stack.
Collaboration & Leadership
  • Collaborate closely with product, QA, DevOps, and platform teams.
  • Mentor junior engineers and support technical decision-making across sprints.
Required Skills & Experience
  • 7+ years in Java development with strong expertise in Spring Boot.
  • Proven experience decomposing monolithic applications and rebuilding them as RESTful microservices.
  • Strong knowledge of REST architecture principles and best practices.
  • Proven experience designing and building REST APIs at scale.
Preferred Skills
  • Experience with API Gateways (AWS API Gateway, Kong).
  • Knowledge of Kafka, RabbitMQ.
Benefits

This is a high-impact role where your expertise will directly influence system scalability, performance, and developer experience.
