• Contribute to event-driven architectures using Kafka for asynchronous, decoupled communication between services.
• Containerize and deploy services to Kubernetes on Azure, leveraging Azure Blob Storage, Azure Key Vault, and related Azure services.
• Apply CI/CD best practices using GitHub Actions, ArgoCD, Helm, and JFrog/Artifactory.
• Participate in architecture, design, and planning sessions; produce clean, reusable, testable, and well-documented code.
• Perform code reviews, root-cause analysis, and resolution of complex defects across the stack.
• Implement security, data protection, and audit controls appropriate to a PHI/HIPAA environment.
• Write unit, integration, and end-to-end tests; contribute to meeting platform test-coverage standards.
• Collaborate with engineers (onshore and offshore) and share best practices across the team.

Requirements

• 4+ years of professional software engineering experience building enterprise-scale applications.
• 2+ years of hands-on experience with Java, Spring, and Spring Boot in a microservices architecture.
