GDIT is seeking a highly skilled Software Engineer/Microservices to support software development for our USPS customers. The Microservices Developer will be responsible for designing, building, and maintaining scalable backend services that power the platform’s RESTful APIs.

Required Experience

• A minimum of 8 years of experience in Java development, with at least 2 years of microservices development experience.

• Ability to design, build, and maintain Spring Boot microservices using Java 21 and Java 25.

• Ability to create and evolve RESTful APIs with clear contracts, versioning, and backward compatibility.

• Implement input validation, error handling, idempotency, and standardized response models.

• Integrate services with on-prem and AWS-hosted databases during migration phases.

• Plan and execute data-access changes to support hybrid connectivity (on-prem to AWS) safely.

• Optimize database interactions, including query tuning, connection pooling, and transaction boundaries.

• Containerize services and maintain production-ready Docker images.

• Deploy and operate services on Kubernetes with health probes, resource limits, and autoscaling.

• Build and maintain CI/CD pipelines for build, test, security scan, and deployment automation.

• Implement secure service-to-service and client authentication/authorization.

• Manage secrets and configuration using AWS-native and Kubernetes-native approaches.

• Add observability: structured logging, metrics, distributed tracing, dashboards, and alerting.

• Troubleshoot incidents across application, container, cluster, network, and database layers.

• Improve resiliency with retries, timeouts, circuit breakers, and graceful degradation patterns.

• Participate in migration planning from on-prem infrastructure and data stores to AWS.

• Support release validation in staging and production, including rollback readiness.

• Write and maintain unit, integration, contract, and performance tests.

• Address vulnerabilities by upgrading dependencies and remediating CVEs in application libraries.

• Collaborate with QA, platform, security, and architecture teams on standards and best practices.

• Document APIs, operational runbooks, and service ownership responsibilities.

• Experience with Agile development environments with tools like VersionOne (or similar platform)
