Network Administrator

ROLE SUMMARY

We are seeking a highly capable and hands-on Network Administrator to join our IT team. The ideal candidate brings solid practical experience across Windows Server environments, cloud infrastructure, physical data centre operations, surveillance systems, and storage — and is equally comfortable drafting a policy document as they are pulling a cable through a server rack. This is a key infrastructure role requiring both technical depth and an ownership mindset.

KEY RESPONSIBILITIES

1. Windows Server Administration

•       Monitor server performance, event logs, and ensure uptime SLAs are met

•       Manage user accounts, permissions, and role-based access control (RBAC)

•       Patch management, scheduled maintenance windows, and OS hardening

2. Backup Management & Disaster Recovery

•       Design, implement, and maintain backup policies using tools such as Veeam, Acronis, or equivalent

•       Manage full, incremental, and differential backup schedules across physical and virtual systems

•       Test and validate restore procedures on a regular basis — ensuring RTO/RPO targets are met

•       Maintain offsite/cloud backup copies and ensure encryption compliance

•       Document DR plans and lead or support annual DR drills

3. Server Rack & Data Centre Management

•       Physical installation, labelling, and management of servers, switches, patch panels, and PDUs in racks

•       Maintain cable management standards — structured cabling (Cat6/6A/Fibre), proper labelling, and documentation

•       Monitor temperature, power draw, and cooling in the server room/DC

•       Manage hardware lifecycle including procurement support, asset tagging, and decommissioning

•       Maintain accurate rack diagrams and infrastructure documentation

4. Cloud & VPS Infrastructure (AWS, Azure, and Others)

•       Provision and manage cloud instances (EC2, VMs, Lightsail, or equivalent VPS environments)

•       Configure security groups, IAM roles, VPCs, subnets, and firewall rules on AWS / Azure

•       Manage cloud-hosted services including web servers, databases, and application environments

•       Monitor cloud resource utilisation and perform right-sizing / cost optimisation

•       Manage DNS zones via Route 53, Cloudflare, or similar platforms

•       Support hybrid cloud connectivity (Site-to-Site VPN, ExpressRoute, Direct Connect)

•       Maintain cloud documentation and enforce tagging standards and naming conventions

5. NAS (Network Attached Storage) Management

•       Configure and maintain NAS solutions (Synology, QNAP, or enterprise-grade equivalents)

•       Manage RAID configurations, storage pools, shared folders, and volume snapshots

•       Set up user/group access permissions and integrate NAS with Active Directory

•       Monitor disk health, capacity trends, and generate storage utilisation reports

•       Configure replication tasks and sync jobs for redundancy

6. Network Camera, NVR & Surveillance Systems

•       Deploy and maintain IP cameras (Hikvision, Dahua, Axis, or similar) and NVR/DVR systems

•       Configure camera layouts, motion zones, schedules, and video retention policies

•       Manage remote access to surveillance feeds with appropriate access controls

•       Troubleshoot connectivity, image quality, and recording issues

•       Coordinate with physical security teams for installations and expansions

7. Network Infrastructure & General IT

•       Configure and manage switches (managed L2/L3), routers, and access points (Cisco, Ubiquiti, Meraki, etc.)

•       Set up and manage VLANs, QoS policies, and inter-VLAN routing

•       Maintain and monitor firewalls (FortiGate, pfSense, Sophos, or similar)

•       Manage VPN solutions — SSL VPN, IPSec, and remote access configurations

•       Monitor network traffic using tools such as PRTG, SolarWinds, Zabbix, or Nagios

•       Respond to and resolve network outages, slowdowns, and connectivity issues — including after-hours if required
