Minimum of 5 years’ experience administering and maintaining global IT infrastructure in both on-premises and cloud environments
At least 4 years’ advanced proficiency with Windows and Linux systems administration
3+ years of hands-on SAN (Storage Area Network) management experience
2+ years implementing and supporting SAP systems, including S/4HANA
3+ years working with and advanced skills in network, server, and virtualization technologies, with expertise in VMware. Experience with VMware alternatives such as Proxmox a plus
2+ years proven experience automating tasks using Python and PowerShell
Demonstrated ability to monitor, analyze, and optimize system performance, with at least 3 years in similar roles
2+ years executing disaster recovery procedures and ensuring compliance
Experience supporting complex, cross-functional global projects for 3 years or more
