Lead network upgrades, migrations, and infrastructure improvement projects
	
Implement secure remote access solutions (VPN, IPsec, SSL/TLS, SSH)
	
Enforce network security best practices, including firewall rules, IDS/IPS, encryption, and PKI
	
Monitor network performance, capacity, and security using appropriate tools
	
Support disaster recovery and business continuity planning
	
Manage patching, updates, and configuration backups
	
Produce clear documentation for network configurations and DR procedures
	
Provide technical guidance and mentoring to junior engineers
	
Participate in on‑call support and incident response when required

We’re looking for someone who brings:

Proven experience designing and managing large‑scale enterprise networks
	
Strong understanding of routing and core protocols (TCP/IP, DNS, DHCP, NFS)
	
Solid background in network security (firewalls, VPNs, encryption standards)
	
Hands‑on experience with virtualisation platforms such as VMware vSphere
	
Familiarity with containerisation technologies (advantageous)
	
Good knowledge of Windows Server environments
	
Certifications such as CCNP, CCIE, JNCIP or equivalent (highly desirable)
	
Experience working within structured IT environments (ITIL beneficial)
	
A proactive, solutions‑focused approach and strong communication skills
