Position Summary

We are seeking a skilled Network Administrator to join the IT team and support the day-to-day operation, maintenance, and optimization of an enterprise network environment.

• Monitor network performance and capacity
• Maintain accurate network documentation, diagrams, and operational procedures
• Support cloud and hybrid connectivity, including VPNs and basic cloud networking components (Azure preferred)
• Assist in maintaining and supporting VoIP infrastructure
• Collaborate with vendors and service providers for issue resolution and service delivery
