• Experience utilizing API testing and validation tools such as Postman, including creating and maintaining collections, managing environments, and developing automated test scripts.
• Solid experience with PostgreSQL or comparable relational databases, including schema design, indexing, and performance optimization.
• Hands-on experience with Docker for building, running, and troubleshooting containerized applications.
• Exposure to Kubernetes concepts such as Deployments, Services, ConfigMaps, and Secrets, with experience deploying applications to clusters.
• Experience writing unit and integration tests using JUnit and Mockito, with a strong commitment to code quality and automated testing practices.
• Solid understanding of object-oriented programming principles, design patterns, and clean-code methodologies.
• Proficiency with Git and modern source control workflows using platforms such as GitHub, GitLab, or Bitbucket.
• Familiarity with CI/CD pipelines and DevOps practices using tools such as Jenkins, GitLab CI, or GitHub Actions.
• Experience using build and dependency management tools such as Maven or Gradle.
• Experience working within Agile development environments using Scrum or Kanban methodologies and tools such as Jira.
• Strong written and verbal communication skills with the ability to collaborate effectively across technical and non-technical teams.
• Ability to obtain and maintain a U.S. Government Public Trust clearance.
• Ability to work effectively in a fully remote, collaborative team environment.

Requirements

• Experience with Kubernetes-native deployment and development tools such as Skaffold, Kustomize, or Helm.
• Experience with Redis for caching, distributed locking, rate limiting, or pub/sub implementations.
• Familiarity with asynchronous messaging technologies such as Apache Kafka or RabbitMQ.
• Understanding of microservices architecture patterns including service discovery, circuit breakers, and API gateways.
• Experience with API management platforms such as Kong, Apigee, or AWS API Gateway for proxies, rate limiting, and access control.
