3What this role really is

A Head of Networks keeps core network infrastructure running, owning specific segments and systems and fixing problems when they arise.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Cisco IOS-XE/NX-OS & Juniper Junos Intermediate

Executing configuration changes, troubleshooting interfaces and routing, gathering diagnostic data on our core network devices.

Ansible & Python (Netmiko/NAPALM) Basic

Running pre-written Ansible playbooks for routine tasks (e.g., patching, config backups). Using simple Python scripts to gather network data or automate small, repetitive checks.

SolarWinds NPM / Zabbix / Datadog Intermediate

Using dashboards to monitor network health, identify alerts, and gather initial diagnostic information during incidents.

AWS VPC / Azure VNet Basic

Understanding cloud network concepts, troubleshooting basic security group or Network Access Control List (NACL) issues within our cloud environments.

Palo Alto / Fortinet / Cisco Firepower Intermediate

Managing firewall rules based on approved requests, troubleshooting basic policy interactions, and reviewing logs for security events.

Infoblox / BlueCat / Microsoft DNS Intermediate

Managing IP address reservations, updating DNS records, and troubleshooting DNS resolution paths for internal and external services.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Troubleshooting Path for a P2 Incident Follow a predefined runbook, escalate if the runbook doesn't resolve it. Independently choose the most effective troubleshooting steps, consulting with a senior engineer if stuck or if it requires a non-standard approach. Define the troubleshooting strategy for complex, multi-system incidents, guiding junior engineers.
Configuration Change to a Production Firewall Execute pre-approved changes under direct supervision. Prepare the change request and configuration script, get it peer-reviewed by a senior engineer, and then implement it during an approved change window. Design the firewall policy, review junior engineers' changes, and approve the implementation plan.
Purchasing a New Network Tool/Software Identify a need and report it to your supervisor. Research potential solutions, present a basic business case (cost vs. benefit) for tools up to £1,000, and get manager approval. Evaluate and recommend tools up to £10K, taking into account integration and long-term strategy, presenting to leadership.
Responding to a Security Alert on a Network Device Follow documented procedures, escalate to a senior engineer or security team immediately. Independently investigate the alert, gather evidence, and take initial containment steps (e.g., blocking an IP) after consulting with Security Operations. Lead the response, coordinate with Security Ops, and make critical decisions on containment and eradication.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Ticket Resolution Rate (SLA Adherence)
How many network-related support tickets you resolve within their agreed Service Level Agreement (SLA).
Target · 95% of assigned tickets resolved within SLA

If you're assigned 20 tickets in a month, you should be closing at least 19 of them before their SLA clock runs out. This shows you're on top of things.

Network Change Success Rate
The percentage of network changes you implement that go live without causing a new incident or service disruption.
Target · >99.8% successful changes (less than 1 incident per 500 changes)

If you make 50 changes over a quarter, we'd expect all of them to go through without a hitch. One small mistake can take down a whole office, so precision is key.

Mean Time to Resolution (MTTR) for Assigned Incidents
The average time it takes you to diagnose and restore service for network incidents you're assigned.
Target · Reduce MTTR for P1/P2 incidents by 15% year-over-year (e.g., from 60 mins to 51 mins)

If a core switch goes down, we're looking at how quickly you can get it back up. Every minute counts when the business is impacted.

Network Device Uptime for Owned Systems
The percentage of time that the specific network devices or segments you're responsible for are fully operational.
Target · 99.9% uptime for core access switches and firewalls you manage

If you're looking after the network for our London office, we expect those devices to be available almost all the time. Downtime is a big deal.

Documentation Quality & Completeness
How well you maintain and update network diagrams, configuration guides, and troubleshooting procedures for the systems you own.
  • Regular updates to Confluence/Wiki
  • diagrams match reality
  • junior engineers can follow your guides
  • positive feedback from peers during handovers.
Proactive Issue Identification
Your ability to spot potential network problems before they become major incidents, often by noticing trends in monitoring data.
  • Reporting potential capacity issues before they hit
  • flagging unusual traffic patterns
  • suggesting preventative maintenance based on observations
  • fewer 'surprise' outages.
Collaboration & Knowledge Sharing
How effectively you work with other teams (like servers, security, and IT support) and share your network knowledge with colleagues.
  • Positive feedback from other teams
  • active participation in team knowledge sessions
  • helping junior engineers get unstuck
  • clear communication during incidents.
Problem Solving Rigour
The systematic and logical approach you take to troubleshooting, ensuring root causes are identified rather than just applying quick fixes.
  • Detailed post-mortems for incidents you've led
  • asking for data (p-caps, logs) before making changes
  • demonstrating a clear thought process during incident calls
  • incidents not recurring due to proper fixes.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Tricky Puzzles

You get a real kick out of figuring out why something isn't working when it 'should' be. That deep dive into logs, packet captures, and config files to find the one misconfigured setting that's causing chaos – that's your happy place.

Spending an afternoon tracking down an asymmetric routing issue across multiple firewalls and then seeing traffic flow perfectly again.

Keeping Things Running Smoothly

There's a quiet satisfaction in knowing the network you manage is stable, performant, and reliable. You enjoy the feeling of contributing to the foundational stability of the business, even if it's often invisible.

Monitoring dashboards showing green lights across all your devices, knowing you've prevented potential outages.

Continuous Learning & Improvement

The network world changes constantly, and you love staying on top of it. You're always keen to learn about new technologies, better ways to automate, or more efficient troubleshooting techniques.

Spending an evening experimenting with a new Ansible module for network configuration or diving into a new cloud networking concept.

What frustrates people
  • The 'Guilty Until Proven Innocent' Protocol: Every application slowdown or glitch seems to default to 'it's the network,' forcing you to spend hours proving otherwise with packet captures and latency graphs.
  • Vendor Support Black Holes: Getting stuck in endless loops with Tier 1 support for critical circuit issues, only to be asked basic questions you've already answered.
  • The Invisibility Tax: When the network is running perfectly, no one notices. You only get attention when something breaks, which can feel like thankless work.
  • Legacy Gear in a Dark Closet: Having to maintain that one ancient switch or router that's out of support, can't be automated, and is critical to some obscure service, but can't be replaced due to budget or political battles.
What this role does not give you
  • A quiet, predictable routine: Expect urgent requests and unexpected outages to disrupt your plans regularly.
  • Immediate, visible glory: Your best work often goes unnoticed because it means things are just working as they should.
  • Complete autonomy over budget: While you'll propose solutions, budget approval for significant purchases will sit with your manager or lead.

8Who you work with

Your work directly underpins almost every business function. If the network isn't working, our staff can't work, our customers can't access our products, and frankly, we lose money. You're a critical part of keeping the lights on and the business moving.

Inside the business
  • Internal IT Support Team (they'll be calling you about network issues)
  • Server and Storage Teams (you'll need to work with them on connectivity)
  • Application Development Teams (they'll need network access for new services)
  • Project Managers (they'll be chasing you for network deliverables)
  • Security Operations (you'll work together on firewall policies)
Outside the business
  • Internet Service Providers (ISPs) and Telcos (for circuit issues)
  • Hardware Vendors (Cisco, Juniper, Palo Alto support)
  • Managed Service Providers (MSPs) for specific tools

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 2-3 years of hands-on experience as a Network Engineer or similar role, where you've been responsible for configuring and troubleshooting production networks.
  • Proven experience with Cisco IOS-XE/NX-OS or Juniper Junos in a live environment – we're not looking for purely lab experience here.
  • A solid understanding of routing protocols (OSPF, BGP) and switching technologies (VLANs, Spanning Tree, LACP).
  • Experience with network monitoring tools (e.g., SolarWinds, Zabbix, Datadog) to identify and diagnose issues.
  • Demonstrable experience taking ownership of network incidents and driving them to resolution, including clear communication during outages.
  • A good grasp of network security fundamentals, including firewall concepts and policy management.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Network Observability & AIOps

Just monitoring if a device is up or down isn't enough anymore. We need to understand network performance, user experience, and predict failures. AIOps tools are changing how we do this.

Network telemetry (NetFlow, sFlow, IPFIX) · Log aggregation and analysis (ELK Stack, Splunk) · Time-series databases (Prometheus, InfluxDB) · Custom dashboarding (Grafana) · Machine learning for anomaly detection

  • This week: Dive deeper into our existing monitoring tools and understand how alerts are configured.
  • This month: Learn how to build a custom dashboard in Grafana using existing data sources.
  • Month 2: Research different network telemetry types and how they can be used for deeper insights.
  • Month 3: Explore basic concepts of AIOps platforms and how they use machine learning.

Quick win: Improve one existing network dashboard to show more meaningful performance metrics, not just uptime.

Zero Trust Network Access (ZTNA)

The old 'trust everyone inside the firewall' model is dead. Zero Trust is the future of network security, and you'll need to understand how to implement and manage it.

Micro-segmentation principles · Identity-based access control · Context-aware policies (user, device, location) · Software-Defined Perimeters (SDP) · Continuous verification

  • This week: Read up on the core principles of Zero Trust Architecture.
  • This month: Understand how our current firewalls could support basic micro-segmentation.
  • Month 2: Research ZTNA vendors and their approaches (e.g., Palo Alto Prisma Access, Zscaler).
  • Month 3: Think about how ZTNA would impact our existing network design and user access.

Quick win: Identify one small internal application where you could apply stricter, identity-based network access controls, even if it's just a conceptual exercise.

11Staying current once you are in

What people here do to keep up
  • Regularly follow industry blogs and news sources (e.g., Packet Pushers, EtherealMind) to stay current with network trends and technologies.
  • Participate in online network communities or forums to learn from others and share your knowledge.
  • Attend webinars or virtual conferences on specific network technologies or security topics.
  • Dedicate time each week to labbing up new configurations or troubleshooting scenarios in a virtual environment (e.g., EVE-NG, GNS3).

12The rising capability

The rising capability

Zavmo analysis

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Network Automation with Python & APIs

Manual configuration is slow, prone to errors, and just doesn't scale anymore. Our competitors are automating everything, and so should we. Knowing how to script network tasks means you can do in minutes what used to take hours.

  • Network APIs (RESTCONF, NETCONF)
  • Python libraries (Netmiko, NAPALM, Nornir)
  • Idempotency in automation scripts
  • Version control for network configurations (Git)
  • Basic CI/CD pipelines for network changes

Cloud-Native Networking Concepts

More and more of our infrastructure is moving to the cloud. You can't just apply on-prem network thinking directly. Understanding how cloud networks are designed and managed is becoming non-negotiable.

  • Virtual Private Clouds (VPCs) and Virtual Networks
  • Security Groups and Network Access Control Lists (
  • Cloud routing (Transit Gateway, Virtual WAN)
  • Identity and Access Management (IAM) for network r
  • Hybrid connectivity (Direct Connect, ExpressRoute)

The ten Future Fluencies

Zavmo analysis

The credential is what you can do today. These are what keep you valuable.

A qualification proves you can do the job as it's defined today. These ten are what decide whether you're still the obvious person for it in five years. They're the capabilities employers are now writing into senior roles faster than people are learning them. Zavmo weaves them through whatever you study, so you come out with both: the credential and the fluency.

The highlighted ones are the Fluencies your role leans on hardest, from how Head of Networks is actually changing.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of network engineering involves repetitive tasks, sifting through logs, and drafting reports. What if you could offload a good chunk of that to AI? We're building an AI Hub to do just that, giving you back precious time to focus on the really interesting, complex problems.

For a Head of Networks (Level 002), AI isn't about replacing you; it's about making you incredibly more efficient. Imagine spending less time debugging and more time designing. Our AI Hub is designed to help you automate the mundane, predict the unpredictable, and communicate more effectively.

AI-Powered Anomaly Detection

Use AIOps platforms like Datadog or BigPanda to analyse network telemetry in real-time. This helps you automatically spot weird deviations from normal traffic patterns or unusual latency spikes that often predict an outage before it actually happens. No more sifting through millions of log lines manually.

Predictive Capacity Planning

Feed your historical bandwidth usage, anticipated business growth, and circuit costs into an AI model. This can forecast exactly when and where your network links might get saturated, giving you data-driven insights to make proactive budget requests for upgrades, rather than reactive scrambles.

Automated Firewall Policy Audit

Use AI-driven tools to scan your firewall rule sets. These tools can compare your rules against security best practices, compliance frameworks (like PCI-DSS), and actual traffic flows. This helps you quickly identify risky, redundant, or completely unused rules that need cleaning up – a task that usually takes ages.

Incident Report Auto-Drafting

After an incident, use a Large Language Model (LLM) to parse through your Slack channels, alert streams, and ticket timelines. It can generate a structured first draft of a post-mortem report, saving you hours of administrative overhead. You can then focus on the actual root cause analysis and corrective actions, not just writing it all down.
