About The Position

We are seeking an experienced Senior Java Developer to join the CSMS modernization team. You will design, develop, and maintain mission-critical microservices and applications that support child support case management operations. The role requires strong experience in microservices architecture — building, deploying, and maintaining loosely coupled, independently deployable services. Your work will span web application development, REST API services, batch processing, and system integrations within a cloud-native environment.

Requirements

7+ years of professional Java development experience
Strong proficiency in Java 21 (records, sealed classes, pattern matching, virtual threads)
Proven experience designing and building microservices architectures — service decomposition, API gateway patterns, service discovery, and distributed configuration
Extensive experience with Spring Boot and the Spring ecosystem (Spring MVC, Spring Data, Spring Security, Spring Cloud)
Hands-on experience with Spring Batch for large-scale batch processing
Solid understanding of Hibernate/JPA for ORM and database interaction
Experience with PostgreSQL or similar relational databases
Proven track record of building and consuming RESTful APIs with proper versioning and contract-first design
Experience with inter-service communication patterns (REST, messaging queues, event-driven)
Experience deploying and operating microservices on AWS (EC2, ECS/EKS, RDS, S3, SQS, Lambda)
Familiarity with CI/CD tools (Jenkins, GitHub Actions, or similar) for microservices deployment pipelines
Strong understanding of software design patterns, SOLID principles, and clean code practices
Experience with Git version control and collaborative development workflows
Understanding of distributed system concerns: fault tolerance, circuit breakers, retries, and observability

Nice To Haves

Experience with government or public sector projects
Hands-on experience with microservices patterns such as saga, CQRS, event sourcing, and API composition
Familiarity with service mesh technologies
Experience with containerization (Docker) and orchestration (Kubernetes/ECS) for microservices deployment
Knowledge of message-driven architecture (SQS, SNS, Kafka) for asynchronous inter-service communication
Knowledge of API gateway solutions (AWS API Gateway, Spring Cloud Gateway)
Experience with centralized logging and distributed tracing across microservices (CloudWatch, Splunk, Datadog, Zipkin, OpenTelemetry)
Knowledge of infrastructure-as-code (Terraform, CloudFormation)
Understanding of OAuth2/OpenID Connect for securing microservices
Knowledge of database-per-service patterns and database migration tools (Flyway, Liquibase etc)

Responsibilities

Design, develop, and maintain microservices using Spring Boot, following domain-driven design and service decomposition best practices
Build and deploy loosely coupled, independently deployable services with well-defined API contracts
Develop scalable web applications, RESTful APIs, batch jobs, and integration services for the application platform
Develop and optimize Spring Batch jobs for high-volume data processing, reporting, and scheduled workflows
Implement data access layers using Hibernate/JPA against PostgreSQL databases
Manage inter-service communication patterns including synchronous REST calls and asynchronous messaging
Collaborate with architects and business analysts to translate requirements into technical solutions
Participate in code reviews, enforce coding standards, and mentor junior developers
Troubleshoot application issues and provide timely resolutions across distributed microservices
Contribute to CI/CD pipeline improvements and deployment automation for microservices
Write unit and integration tests to ensure code quality and reliability
Work with cross-functional teams on system integration efforts including third-party and inter-agency data exchanges
