Job description

Senior Network Specialist

The network doesn’t manage itself. (Unfortunately.)

Senior Network Specialist to keep the infrastructure stable, secure, and available across every site. You’ll own the day-to-day running of the network that supports one of South Africa’s largest dairy and food businesses from the core to the edge, from the patch rooms to the vendors.

What you’ll actually do

• Run the operational administration of routers, switches, wireless, internet, WAN, and LAN infrastructure.
• Manage firewall, VPN, DMZ, APN, proxy, and fixed connectivity (fibre and Ethernet).
• Keep network performance and availability inside SLA, working with the outsourced NOC and fixing issues before they become outages.
• Work with ISPs and third-party providers on incidents, maintenance, and upgrades.
• Handle user calls and incidents daily.
• Maintain accurate network diagrams, logical maps, SOPs, and configuration documentation.
• Drive or support small network projects, upgrades, and continuous improvement.

Requirements

• Matric plus a National Diploma or Bachelor’s degree in IT.
• CCNA and CCNP (or equivalent depth).
• CompTIA Network+ is useful; Fortinet, Palo Alto, or other firewall certifications are strongly preferred.
• ITIL Foundation.
• Solid hands-on experience with enterprise LAN/WAN/wireless, firewalls, VPNs, and DMZs.
• Proven ability to work with ISPs and managed service providers.
• Clear documentation habits and the ability to talk to both technical and non-technical people without creating more problems.

If you know how to keep a multi-site network reliable, document it properly, and stop small issues from becoming large ones, this is the role.
