We are seeking a Java Developer with strong experience building scalable backend applications, deploying applications to AWS, and implementing and managing CI/CD pipelines, with particular emphasis on Docker-based deployments and application deployment automation.
Key Responsibilities
Design, develop, test, and maintain scalable Java/Spring Boot backend applications.
Build and enhance RESTful APIs and/or event-driven services and integrate with databases and external systems.
Build, maintain, and enhance CI/CD pipelines to automate application build, testing, security checks, packaging, and deployments.
Containerize applications using Docker and manage Docker-based deployments across multiple environments.
Deploy and operate applications on AWS, including containerized application deployments using ECS/EKS.
Own and support the end-to-end application deployment lifecycle, including configuration, deployment validation, troubleshooting, rollback, and production support.
Drive improvements in deployment automation, reliability, repeatability, and speed, reducing manual deployment activities.
Troubleshoot CI/CD and application deployment failures, perform root-cause analysis, and implement permanent fixes.
Write clean, maintainable code with strong unit/integration test coverage and participate in code reviews.
Collaborate with application, platform, and DevOps teams to improve CI/CD and deployment standards and practices.
Participate in Agile teams (planning, estimation, standups, retrospectives) and contribute to technical design.

Experience with application deployment automation, environment configuration, deployment troubleshooting, and rollback strategies.
Understanding of container orchestration and deployments using Kubernetes/EKS.
Solid knowledge of relational databases (PostgreSQL/MySQL/Oracle) and SQL; NoSQL exposure is a plus.
