Java Developer-Level III

Mandatory Qualifications:

1. Level III- More than seven (7) years of experience working on complex projects with 2 or more years in a leadership role as a Developer
2. 7+ years of professional Java development experience with strong proficiency in Java 21 (records, sealed classes, pattern matching, virtual threads). One to three years of experience designing and building microservices architectures — service decomposition, API gateway patterns, service discovery, and distributed configuration; deploying and operating microservices on AWS (EC2, ECS/EKS, RDS, S3, SQS, Lambda).
3. ​Seven years of experience with Spring Boot and the Spring ecosystem (Spring MVC, Spring Data, Spring Security, Spring Cloud); Spring Batch for large-scale batch processing; solid understanding of Hibernate/JPA for ORM and database interaction; experience with PostgreSQL or similar relational databases; building and consuming RESTful APIs with proper versioning and contract-first design; experience with inter-service communication patterns (REST, messaging queues, event-driven).

Desirable Qualifications:

1. ​Experience with government or public sector projects
2. ​Familiarity with CI/CD tools (Jenkins, GitHub Actions, or similar) for microservices deployment pipelines; distributed system concerns: fault tolerance, circuit breakers, retries, and observability.
3. ​Hands-on experience with microservices patterns such as saga, CQRS, event sourcing, and API composition; service mesh technologies and API gateway solutions (AWS API Gateway, Spring Cloud Gateway)
4. ​Experience with Git version control and collaborative development workflows; strong understanding of software design patterns, SOLID principles, and clean code practices 
5. ​Experience with containerization (Docker) and orchestration (Kubernetes/ECS) for microservices deployment 
6. ​Knowledge of message-driven architecture (SQS, SNS, Kafka) for asynchronous inter-service communication; database-per-service patterns and database migration tools (Flyway, Liquibase etc) 
7. ​Experience with centralized logging and distributed tracing across microservices (CloudWatch, Splunk, Datadog, Zipkin, OpenTelemetry) 
8. ​Knowledge of infrastructure-as-code (Terraform, CloudFormation); OAuth2/OpenID Connect for securing microservices 

Key Responsibilities:

• Design, develop, and maintain Spring Boot microservices using 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.
• Develop and optimize Spring Batch jobs for high-volume data processing, reporting, and scheduled workflows.
• Implement data access layers using Hibernate/JPA with PostgreSQL databases.
• Manage synchronous REST communication and asynchronous messaging between microservices.
• Collaborate with architects and business analysts to translate requirements into technical solutions.
• Participate in code reviews, enforce coding standards, and mentor junior developers.
• Troubleshoot distributed microservice application issues and provide timely resolutions.
• Contribute to CI/CD pipeline improvements and deployment automation.
• Write unit and integration tests to ensure code quality and reliability.
• Support system integration efforts, including third-party and inter-agency data exchanges.
• Work with cross-functional teams on application and system integration activities.
• Support cloud-native application development, deployment, and maintenance.
