• At least 7 years of hands-on experience managing Windows-based systems and VMware environments.
• A minimum of 3 years supporting infrastructure within regulated or high-compliance industries (e.g., financial services).

• Deep experience with Windows system hardening and patching tools such as WSUS or SCCM.
• Skilled in VMware environment builds, including vCenter setup, patching, and host configuration.
• Proficient in Active Directory administration and GPO policy management.
• Familiarity with vSphere core technologies such as vMotion, distributed switches, and HA clusters.
• Experience with scripting and automation (PowerShell, Ansible) is a plus.
