Core areas (must have):
- Strong understanding of TCP/IP, OSI model, and routing/switching protocols (BGP, OSPF, QoS, VPNs, VLANs).
- Network virtualisation (NSX-T): design, configuration, and support of NSX-based networking environments.
- Software-defined networking: implementation of logical switching, routing, and micro-segmentation.
- Integration of NSX networking within virtualised and platform environments (e.g. VCF).
- Hands-on experience with Cisco or equivalent multi-vendor network equipment.
- Network security technologies (firewalls, IDS/IPS, VPN, segmentation).
- Familiarity with virtualisation and cloud networking concepts.
- Network monitoring, diagnostic, and analytics tools.
- Understanding of ITIL and service management frameworks.
- Delivery within secure / enterprise / defence environments.
Desirable:
- VMware NSX-T deep expertise and certification (or equivalent experience).
- VCF networking integration (vSphere, vSAN, Aria Suite).
- Overlay / underlay network design concepts.
- Automation of network configuration (Ansible, Terraform, APIs).
- Integration with security tooling (SIEM, SOC platforms).
- Cloud networking (AWS, Azure) and hybrid connectivity.
- Experience working in secure or regulated environments.
