Experience with Azure DevOps pipelines
Good understanding of software deployment lifecycle and production environments
Experience redesigning application infrastructure or architecture

Responsibilities

Design, maintain, and improve cloud infrastructure and application architecture using AWS CDK

Implement and support CI/CD pipelines (Azure DevOps)
Ensure infrastructure reliability, security, compliance, and observability
