Perform day-to-day infrastructure troubleshooting across servers, storage, networking, and virtualization layers
Collaborate with internal teams on system upgrades, improvements, documentation, and operational best practices
Assist and provide backup support to the Power BI team as needed

Required Skills & Experience: 4+ years of experience as a Systems Administrator or similar infrastructure-focused role
Strong hands-on experience with on-prem infrastructure (non cloud-centric)
Solid understanding of virtualization, particularly Hyper-V
Experience building, managing, and monitoring backup solutions
Strong knowledge of Windows Server, Active Directory, and Microsoft-based environments
Experience supporting network infrastructure; Fortinet experience preferred (firewalls, switches, wireless)
Power BI experience preferred, or willingness to learn (approximately 20% of the role)
