As part of a collaborative Agile team, you will work closely with senior engineers, architects, and cross-functional stakeholders to deliver high-quality software solutions. Responsibilities include writing clean, maintainable, and well-tested code, participating in technical design discussions, troubleshooting complex issues, and contributing to continuous improvement initiatives. This position offers an excellent opportunity for a developer with a strong foundation in Java and Spring Boot to further expand their expertise in Kubernetes, distributed systems, cloud-native architectures, and modern DevOps practices within a culture that emphasizes mentorship, technical excellence, and professional growth.

Responsibilities 

• Design, develop, and maintain scalable RESTful APIs and backend microservices using Java 21+ and modern Spring Boot frameworks.
• Develop, optimize, and maintain PostgreSQL database schemas, queries, and migration scripts to ensure high performance and reliability.
• Implement caching, session management, and lightweight messaging solutions using Redis.
• Containerize applications using Docker and deploy services to Kubernetes environments, leveraging tools such as Skaffold for streamlined local development workflows.
• Develop and maintain comprehensive unit and integration tests using JUnit and Mockito to ensure code quality and application stability.
• Create, maintain, and validate API documentation and test suites using Postman and OpenAPI/Swagger specifications.
• Contribute to CI/CD automation pipelines using tools such as Jenkins, GitLab CI, or GitHub Actions to support efficient build, testing, and deployment processes.
• Participate actively in Agile Scrum ceremonies, including backlog refinement, sprint planning, story estimation, sprint reviews, and retrospectives.
• Collaborate with senior engineers, product managers, architects, and cross-functional stakeholders to translate business and technical requirements into scalable solutions.
• Participate in peer code reviews by providing and incorporating constructive feedback to maintain coding standards and engineering best practices.
• Troubleshoot application issues, identify performance bottlenecks, and implement improvements to enhance system reliability, observability, scalability, and maintainability.
• Apply secure software development practices, including authentication and authorization standards such as OAuth2 and JWT, while adhering to federal data security requirements.
• Maintain accurate and up-to-date technical documentation for APIs, services, system components, and development processes.
