Job Description

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)

Flexible work from home options available.
