• Develop and optimize Spring Batch jobs for high-volume processing and scheduled workflows.
• Implement data access using Hibernate/JPA and PostgreSQL.
• Collaborate with architects, business analysts, and cross-functional teams to translate requirements into technical solutions.
• Participate in code reviews, enforce development standards, and mentor junior developers.
• Troubleshoot distributed application and microservices issues.
• Support CI/CD pipelines, deployment automation, unit testing, and integration testing.
• Support third-party and inter-agency system integrations.

Mandatory Qualifications

• 7+ years of professional Java development experience.

• Experience with inter-service communication using REST, messaging queues, and/or event-driven patterns.
• Experience deploying and operating microservices on AWS, including services such as EC2, ECS/EKS, RDS, S3, SQS, and Lambda.
• Experience with CI/CD tools such as Jenkins or GitHub Actions.
• Strong knowledge of design patterns, SOLID principles, clean code, Git, and collaborative development.
• Understanding of distributed systems concepts including fault tolerance, circuit breakers, retries, and observability.

Desirable Qualifications

• Experience working on government, state, federal, or other public-sector IT projects.
• Experience with microservices patterns such as Saga, CQRS, event sourcing, and API composition.
• Experience with Docker, Kubernetes/ECS, and service mesh technologies.
• Knowledge of SQS, SNS, Kafka, API Gateway, or Spring Cloud Gateway.
