Network engineers design, build, and maintain the infrastructure that keeps organisational data moving — routers, switches, firewalls, VPNs, and increasingly cloud networking services like AWS VPC or Azure Virtual Network. A typical week involves troubleshooting connectivity issues, rolling out network upgrades, reviewing traffic logs, and collaborating with security teams on firewall policies. You'll find these roles across telecoms companies, managed service providers, banks, and large enterprises. Most network engineers report to an IT manager or head of infrastructure.

Network Engineer CVs must show both technical depth and infrastructure scale. Recruiters want to see your Cisco certifications, the size of networks you manage, and your uptime and incident resolution metrics.
Key Skills to Include
Cisco (CCNA/CCNP), routing and switching, SD-WAN, firewalls (Palo Alto, Fortinet), WiFi design, network monitoring, MPLS, VPN, and ITIL.
Common Mistakes
Listing certifications without describing what you built or managed. CCNP shows knowledge. Managing a 15,000-user network with 99.98% uptime shows capability.
Formatting Tips
One to two pages. Include a Technical Skills section grouped by category. Lead with your certifications and the scale of infrastructure you manage.

Top 5 Interview Questions — Network Engineer
1Walk me through how you would troubleshoot a network outage affecting multiple sites.
Describe a layered approach: check physical connectivity first, then work up the OSI model — IP, routing protocols, application layer. Show you can isolate systematically under pressure.
2What's the difference between OSPF and BGP, and when would you use each?
OSPF is an IGP for routing within a single autonomous system — ideal for internal enterprise networks. BGP is for routing between autonomous systems, used by ISPs and large multi-site organisations. Give a real example of where you've deployed each.
3How have you implemented network segmentation or VLANs in a previous role?
Describe the business reason (security zones, compliance, traffic management) and the technical implementation across managed switches. Mention 802.1Q tagging, inter-VLAN routing, and how you documented the design.
4Tell me about a time a change you made caused unexpected downtime.
Be honest and structured: what the change was, how quickly you identified the cause, how you rolled back, and what change control process you put in place afterwards.
5What certifications do you hold and what are you currently studying for?
State your Cisco (CCNA/CCNP), Juniper (JNCIA/JNCIP), or cloud networking certifications clearly. Showing you're actively studying — CCIE, AWS Advanced Networking — signals you take the career seriously.
How to Tailor Your CV
BT, Cisco, Amazon Web Services, and managed service providers like Computacenter and NTT hire network engineers heavily. Telecoms firms want deep routing and switching experience with proven skills in BGP, MPLS, and carrier-grade infrastructure. Cloud-forward companies prioritise AWS, Azure, or GCP networking certifications and Terraform or Ansible experience for infrastructure-as-code. MSPs want breadth — you'll need to show you can support a diverse client base across multiple environments and switch context quickly.
