• Support firewalls, switches, wireless networks, VPN/SASE connectivity, internet circuits, and site-to-site connections.
• Troubleshoot complex hardware, software, network, authentication, and connectivity issues escalated by the service desk.
• Support remote offices and employees throughout the company.
• Assist with Microsoft 365 migrations, tenant consolidation, server deployments, office integrations, and other infrastructure projects.
• Maintain system documentation, network diagrams, configuration records, inventories, procedures, and knowledge-base articles.
• Assist with endpoint management, mobile device management, security tools, and remote monitoring platforms.
• Review system alerts and logs and respond to potential availability, performance, or security issues.
• Follow company change management, access-control, cybersecurity, and documentation standards.
• Coordinate with technology vendors and service providers to resolve technical issues.
• Participate in an on-call rotation and perform occasional after-hours maintenance when required.
• Perform other technology-related duties as assigned.

Required Qualifications

• Three or more years of experience in systems administration, network administration, or a similar infrastructure support role.
• Practical experience administering Windows Server and Active Directory.
• Experience supporting Microsoft 365, Exchange Online, Entra ID, Teams, SharePoint, and OneDrive.
• Understanding of networking fundamentals, including TCP/IP, DNS, DHCP, VLANs, routing, switching, wireless networking, and VPN technologies.
• Experience with virtualization platforms such as VMware or Microsoft Hyper-V.
• Experience supporting backup, endpoint protection, remote access, and system-monitoring solutions.
• Ability to troubleshoot technical issues methodically and independently.
• Strong documentation, organization, communication, and customer-service skills.
• Ability to prioritize multiple assignments and work effectively in a fast-paced, multi-location environment.
• Ability to explain technical issues clearly to both technical and nontechnical employees.
