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 ## Description * 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. Attend monthly in-person meetings at the Albany office for approved 100% remote arrangements and participate in major milestone meetings as needed ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Bootiful Spring Boot 3](https://www.wearedevelopers.com/videos/537-bootiful-spring-boot-3) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [93 Java Interview Questions You Should Prepare For](https://www.wearedevelopers.com/magazine/14-93-java-interview-questions-you-should-prepare-for) - [Top 10 Java Libraries](https://www.wearedevelopers.com/magazine/364-top-10-java-libraries) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Best Coding Boot Camps in Germany](https://www.wearedevelopers.com/magazine/237-best-coding-boot-camps-in-germany)
