• Embed Infrastructure as Code and automation practices using Terraform, Ansible, and Azure DevOps to enable scalable, repeatable deployments
• Collaborate across cloud, security, infrastructure, and application teams while acting as a subject matter expert, ensuring secure, compliant solutions and continuously improving network platforms

What's in it for you?
