This role focuses on maintaining reliable network connectivity, supporting Microsoft server services, assisting users with infrastructure-related issues, and helping ensure systems operate smoothly across multiple locations. Cybersecurity monitoring and strategy are managed by a third-party provider; this role assists with implementation and coordination as needed.

This is a mid-level, operational role ideal for someone who enjoys working directly with infrastructure and solving practical problems in a business environment.

• Administer VLANs, DHCP, DNS dependencies, VPN connections, and wireless networks.
• Monitor network health using dashboards and alerts; troubleshoot connectivity issues.
• Assist with ISP coordination and WAN connectivity troubleshooting.
• Maintain basic network documentation (diagrams, device inventory, IP addressing).

Systems Administration

• Support Windows Server environments including Active Directory, DNS, and Group Policy.
• Assist with Microsoft 365 administration (Exchange Online, Teams, SharePoint).
• Perform routine system maintenance including patching, updates, and backup verification.
• Support virtualization (VMware) for existing server workloads.
• Provide support for domain-joined endpoints and infrastructure-related issues.

IT Operations Support

• Provide Tier 2/3 support for network and server-related incidents.
• Install and configure switches, access points, servers, and workstations as needed.
• Document support activity and maintain accurate system records.
• Coordinate with vendors for hardware replacement and ISP-related issues.
• Participate in occasional after-hours maintenance windows when required.

Security Coordination (Limited Scope)

• Apply firewall rule updates and configuration changes as directed.
• Implement remediation actions recommended by the third-party security provider.
• Provide logs or documentation for security reviews when requested.

Qualifications

• 3–5 years of experience supporting business network and server environments.
• Hands-on experience with Cisco Meraki (MX/MS/MR) preferred.
• Solid understanding of TCP/IP, VLANs, DHCP, DNS, and VPN concepts.
• Experience supporting Active Directory and Microsoft 365.
• Experience with VMware or similar virtualization platform.
• Strong troubleshooting and problem-solving skills.
• Comfortable working onsite and interacting with end users.
• PowerShell experience is a plus.
• Bilingual (Spanish/English) is helpful but not required.

What Success Looks Like

• Stable network and server operations.
• Prompt resolution of infrastructure-related issues.
• Clear and updated documentation.
• Effective coordination with vendors and security partners.
• Minimal recurring outages or user-impacting issues.
