• Solid experience with automation and configuration management using PowerShell (advanced scripting), Desired State Configuration (DSC), and/or Ansible/SaltStack for Windows.
• Strong understanding of CI/CD concepts applied to Windows environments using GitLab, Azure DevOps, or similar tools.

• Experience with infrastructure provisioning tools like Terraform (including Windows modules) or CDK.
• Strong grasp of Windows performance tuning, debugging, event log analysis, and patching strategy at scale.
• Background in regulated or high-uptime environments such as banking, Forex, or fintech is highly preferred.
• Familiarity with SQL Server automation, .NET Core deployments, and Windows Containers is a plus.
