Our company is looking for a hands-on IT Systems & Network Administrator to manage, maintain, and optimize our on-site IT infrastructure and end-user environment. You will be the go-to technical resource responsible for keeping our Ubiquiti network, Synology servers, virtual machines, RingCentral phone system, and office hardware running smoothly. This is an ideal role for a versatile IT generalist who enjoys owning the full stack—from configuring VLANs and backups to troubleshooting a workstation or office printer.

Key Responsibilities

  • Network Administration (Ubiquiti): Manage, monitor, and troubleshoot our Ubiquiti UniFi ecosystem, including gateways/firewalls, switches, and wireless access points. Configure VLANs, VPNs, firewall rules, and traffic management to ensure reliable, secure connectivity.
  • Servers, Storage & Virtualization: Administer our Synology NAS servers (DSM), including file shares, user permissions, RAID health, and backup schedules. Manage and maintain on-premises Virtual Machines (VMs) and core local services.
  • Unified Communications: Oversee our RingCentral VoIP phone system, including user provisioning, desk phone setup, call queues, IVR auto-attendants, and call routing updates.
  • End-User & Hardware Support: Set up, deploy, and maintain Windows/macOS desktop PCs, laptops, network printers, scanners, and other LAN-connected office devices. Provide responsive day-to-day technical support to staff.
  • Security & Documentation: Apply regular firmware, OS, and software patches across all network gear, servers, and workstations. Maintain up-to-date network diagrams, asset inventories, and standard operating procedures (SOPs).

Preferred Qualifications (Bonus)

  • Experience with Microsoft 365 or Google Workspace administration.
  • Familiarity with endpoint security/antivirus management and automated backup verification.
  • Relevant certifications (e.g., CompTIA Network+, Security+, or Ubiquiti certifications).

Required Qualifications & Skills

  • Experience: 2–4+ years of hands-on experience in a Systems Administrator, Network Administrator, or Tier 2/3 IT Support role.
  • Networking: Strong working knowledge of TCP/IP, DNS, DHCP, VLANs, VPNs, and firewall administration—specifically within a Ubiquiti UniFi environment.
  • Storage & VMs: Direct experience administering Synology NAS devices and managing Virtual Machines (e.g., Synology Virtual Machine Manager, VMware, Hyper-V, or Proxmox).
  • VoIP Systems: Familiarity with cloud phone administration, ideally RingCentral (or similar platforms like 8x8, Zoom Phone, or Vonage).
  • Hardware & Endpoints: Solid troubleshooting skills for physical PCs, Windows OS, shared network printers, and general LAN cabling/peripherals.
  • Soft Skills: Strong communication skills, a customer-service mindset when helping non-technical staff, and the ability to prioritize tasks independently.
