Senior Java Developer - Child Support Management System

Job Description

Senior Java Developer – CSMS (Child Support Management System)

Job Summary:

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.

Key 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

Consultants may be eligible to telecommute for more than 50% of their work hours, up to and including 100% remote work. Telecommuting arrangements require direct manager approval and are subject to change based on program needs. Consultants approved for 100% remote work must attend monthly in-person meetings at the Albany office and be available for major milestone meetings as needed.

Mandatory Qualifications:

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

Desirable Qualifications:

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)
