Assist with cost optimization, tagging, and governance practices for Azure resources in collaboration with cloud architecture and governance teams. Develop and maintain automation scripts using PowerShell, Bash, or Python to streamline operations, deployments, and system monitoring. Contribute to automation toolsets such as Ansible, Git, or CI/CD pipelines in collaboration with infrastructure and platform architecture teams. Participate in automation efforts related to Azure and OpenShift operations, including standardized deployments and configuration management. Ensure system compliance with internal security policies, audit controls, and patching standards. Support vulnerability remediation efforts across supported platforms. Maintain up-to-date documentation of systems, runbooks, technical procedures, and operational standards.
