• Deep expertise with Windows Server, Active Directory, networking, and virtualization platforms (e.g., VMware or Hyper-V)

• Strong scripting and automation skills, particularly with PowerShell

• Hands-on experience with cloud platforms (Azure or AWS) and hybrid IT environments

• Solid understanding of endpoint management, system hardening, and patching

• Familiarity with security best practices in regulated or high-trust environments

• A proactive, self-starting attitude with the ability to work independently in a high-performance setting

• Excellent communication skills, comfortable interacting with both technical and non-technical stakeholders
