1What this role really is

As a Lead Network Engineer, you're not just fixing things; you're shaping how our network works, day in, day out. You'll be the person who designs the solutions, then makes sure they actually get built and run properly. This isn't a purely hands-on role anymore, though you'll still get your hands dirty when things get really tricky. Think of it as being the architect and the lead builder for significant parts of our network infrastructure, making sure it's robust, secure, and ready for whatever the business throws at it. You'll lead small teams, mentor others, and make sure our network keeps humming along, even when everyone else is asleep.

4How you'll be judged

The scoreboard, honestly: the hard targets, how often each one is actually looked at, and the quiet human signals that never make it onto a dashboard.

Change Success Rate
Percentage of network changes implemented without causing an incident or rollback.
Target · 99.5% or higher

If you lead 20 network changes in a quarter and only one causes a minor performance blip that's quickly resolved, that's a 95% success rate. We're aiming for near-perfection here, especially on critical infrastructure.

Project Delivery Adherence
Completion of assigned network design and implementation projects on or before the agreed-upon deadline, within budget.
Target · 95% of projects delivered on time and within budget

You're leading the SD-WAN rollout for three new offices. If all three are live and stable by the target date and the costs are within 5% of your initial estimate, that's a win. Missing a key deadline by two weeks because of poor planning isn't.

Reduction in Recurring Incidents
The percentage decrease in repeat incidents related to network areas or services under your design/oversight, through proactive problem management.
Target · 25% reduction YoY for identified problem areas

If a particular branch office keeps reporting 'slow internet' every Tuesday, and your design change or root cause fix eliminates that recurring issue for a full quarter, that's a direct impact on this metric. We track these things.

Network Availability for Key Services
Uptime percentage for critical network services and infrastructure components you've designed or are responsible for.
Target · 99.99% ('four nines') for critical production networks

If the core data centre network you designed has 5 minutes of unplanned downtime in a month, that's roughly 99.988% availability. We're talking seconds and minutes here, not hours. Every second counts.

Quality of Network Designs & Documentation
Your designs are clear, well-thought-out, scalable, and secure. The documentation for these designs is comprehensive, accurate, and easy for others to follow.
  • Other engineers can implement your designs without constant clarification. Your documentation is regularly referenced by the operations team during troubleshooting. Designs are approved by security and architecture review boards with minimal revisions. New solutions are robust and don't introduce unexpected issues.
Mentorship & Team Development
How effectively you guide and develop the junior and mid-level engineers in your team, helping them grow their technical skills and problem-solving abilities.
  • Junior team members consistently improve their troubleshooting skills. They come to you for advice, not just answers. You're regularly conducting code reviews or configuration reviews that genuinely teach, not just correct. Your direct reports feel supported and challenged, and their performance reviews reflect growth.
Proactive Problem Identification
You're not just reacting to incidents; you're spotting potential issues in the network before they become critical problems and addressing them.
  • You present findings from trend analysis (e.g., 'London circuit will saturate in 6 weeks') and propose solutions before users complain. You initiate problem tickets based on observations, not just recurring incidents. You're often the first to flag a potential vulnerability or architectural weakness.
Strategic Influence & Collaboration
Your ability to work effectively with other teams (security, server, dev) and influence technical decisions that impact the network, ensuring alignment on solutions.
  • You're regularly invited to cross-functional planning meetings. Your input on network implications is sought out and respected. You successfully negotiate technical requirements with other teams without creating friction. You're not just 'proving innocence' but actively working towards shared solutions.

5Would you like it

The honest version. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You'll be handed those 'impossible' network problems that have been bouncing around for weeks. You'll get to deep-dive into packet captures, log files, and configuration audits to find the subtle root cause that everyone else missed. It's a constant intellectual challenge.

Figuring out why a specific application is experiencing intermittent latency only when accessed from a particular subnet, tracing it down to a misconfigured QoS policy on a router nobody touched in years.

Building Robust Infrastructure

You'll be designing and implementing new network segments, upgrading core infrastructure, and architecting solutions for high availability and disaster recovery. Your work will directly contribute to the stability and resilience of our entire technical estate.

Leading the design and deployment of a new data centre interconnect, ensuring it meets our 'four nines' uptime requirement and can failover seamlessly.

Technical Leadership & Mentorship

You'll be the go-to person for technical questions from junior engineers, leading small project teams, and providing guidance on best practices. You'll get to shape the technical direction and capability of our network team.

Mentoring a junior engineer through their first complex firewall rule change, guiding them on the process, potential risks, and verification steps, and reviewing their work.

What frustrates people
  • Being the default scapegoat: Every application slowdown or system issue will often be blamed on 'the network' first, forcing you to spend hours proving network innocence with packet captures, only for the developer to eventually find a bug in their code.
  • Vague requirements: Getting a project brief that says 'make the network faster and more secure' without any specific metrics or use cases, leaving you to define the problem yourself.
  • Legacy system handcuffs: Knowing the perfect, modern solution but being stuck with an ancient piece of kit or a vendor contract that prevents you from implementing it.
  • The 2 AM cutover: The unglamorous reality that 90% of significant, career-defining network changes happen on a Saturday night or early Sunday morning when no one else is working.
  • Documentation debt: Trying to troubleshoot a critical but obscure part of the network using diagrams that haven't been updated since 2015, created by an engineer who left the company years ago, and then having to fix them yourself.
What this role does not give you
  • A purely hands-off, strategic role: You'll still be expected to dive into the CLI and troubleshoot when needed, especially for complex issues.
  • A predictable 9-to-5 schedule: Major incidents and critical changes often happen outside of normal business hours, and you'll be part of the on-call rotation.
  • Complete autonomy over the entire network: You'll lead specific areas and projects, but overall strategy and budget are still managed by your manager and above.
  • A quiet, uninterrupted environment: You'll be juggling project work, incident escalations, and mentoring, often in a busy office environment or on conference calls.

6Who you work with

This role directly impacts the reliability, performance, and security of our entire network infrastructure. Your designs and leadership will dictate how well our systems scale, how quickly we can recover from incidents, and how resilient we are against cyber threats. Get it right, and the business runs smoothly; get it wrong, and we're looking at significant downtime, reputational damage, and potentially lost revenue. You're essentially the backbone of our digital operations.

Inside the business
  • Network Engineering Manager (your boss, for strategic alignment)
  • Security Operations Team (for policy enforcement and threat response)
  • Server & Virtualisation Teams (for infrastructure dependencies)
  • Application Development Teams (for connectivity and performance needs)
  • Project Managers (for delivery timelines and resource planning)
  • Head of Infrastructure (for high-level strategy and budget discussions)
Outside the business
  • Network Hardware Vendors (Cisco, Juniper, Palo Alto, etc.)
  • Internet Service Providers (ISPs) and Telcos
  • Managed Service Providers (MSPs) for specific services
  • Security Auditors (occasionally, for compliance reviews)

7What you need before you start

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

  • Proven experience (at least 5-7 years) as a Senior Network Support Specialist or Network Engineer, where you've independently resolved complex Tier 2/3 incidents and led smaller network projects.
  • Demonstrable experience in designing and implementing network changes, including routing, switching, and firewall policies, with a strong track record of successful deployments.
  • Solid understanding of network security principles and hands-on experience with enterprise-grade firewalls (e.g., Palo Alto, Fortinet), including policy creation, NAT, and VPN configurations.
  • Experience mentoring junior technical staff, providing guidance on troubleshooting, configuration, and best practices.
  • A strong grasp of network automation fundamentals, ideally with some practical experience using tools like Ansible or Python for network tasks.
  • Excellent communication skills – both written and verbal – with the ability to explain complex technical concepts clearly to both technical and non-technical audiences.

8What to practise next

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

Network Programmability & API Integration

Manual configuration is a bottleneck. Networks are increasingly managed via APIs. Being able to interact with network devices and controllers programmatically means you can build custom tools, integrate with other systems, and automate complex workflows that aren't possible with just the CLI.

RESTful APIs for network devices and controllers · Data models (YANG, OpenConfig) · Python libraries for network automation (Netmiko, NAPALM, Nornir) · Webhook integration for event-driven automation

  • This week: Learn the basics of making API calls using Postman or Python's `requests` library.
  • This month: Choose one network device or controller we use that has an API and try to retrieve some operational data using Python.
  • Month 2: Experiment with pushing a simple configuration change to a lab device via its API.
  • Month 3: Integrate a network API call into an existing script or automation workflow to gather data or trigger an action.

Quick win: Find a network device with a public API (like Meraki or a virtual router) and try to pull its interface status using a simple Python script. It's a great way to get started.

Zero Trust Network Access (ZTNA) Principles & Implementation

The traditional 'trust internal, distrust external' model is dead. With remote work and cloud adoption, the perimeter has dissolved. ZTNA is the modern security paradigm, and network engineers are crucial to its implementation. This isn't just for security teams; it's fundamental network design.

Never trust, always verify · Micro-segmentation and least privilege access · Identity-driven access control · Contextual access policies · ZTNA vendor solutions (e.g., Zscaler, Palo Alto Prisma Access)

  • This week: Read up on the NIST Zero Trust Architecture model (SP 800-207).
  • This month: Research a couple of ZTNA vendor solutions and understand their core components and deployment models.
  • Month 2: Conduct an internal assessment of one of our existing applications from a ZTNA perspective: who accesses it, from where, and what controls are in place?
  • Month 3: Propose a small proof-of-concept for implementing ZTNA principles for a specific internal service.

Quick win: Start thinking about every network access request with a 'why?' and 'what's the absolute minimum access needed?' mindset. It's a shift in thinking that costs nothing.

9Staying current once you are in

What people here do to keep up
  • Regularly attend industry conferences (e.g., Cisco Live, Juniper NXTWORK, SANS events) to stay current with emerging technologies and best practices.
  • Actively participate in online network engineering communities (e.g., Reddit's r/networking, Packet Pushers podcasts) to learn from peers and contribute your own insights.
  • Maintain a home lab or cloud lab environment to experiment with new network technologies, automation scripts, and security configurations in a safe space.
  • Contribute to open-source network automation projects or create your own small tools to solve common network problems.
  • Pursue advanced certifications in areas like cloud networking, network automation, or specific security vendor technologies that align with our future roadmap.

10How the AI economy is changing work like this

Before we ask anything of you, here's what we can already say about AI and work of this kind:

The new skill this role is being asked for: Network as Code (NaC) & GitOps for Infrastructure

Manual configurations are slow, error-prone, and don't scale. Competitors are already using NaC to deploy network changes in minutes that used to take hours, with fewer errors. This is the future of network operations, making changes auditable and repeatable.

We'll only ever tell you what we can actually back up. No hype, no scare tactics.

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 Lead Network Engineer is actually changing. In about two minutes, the free confidence check asks where you stand on each of the ten. That's the whole check, and it's what makes the plan yours rather than generic.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a big chunk of network engineering involves sifting through mountains of logs, chasing down obscure errors, and drafting documentation. What if you could offload a lot of that grunt work to AI, freeing you up to focus on the really interesting design and architectural challenges? Well, you can.

We're not talking about replacing your job; we're talking about giving you a superpower. Imagine having an AI co-pilot that helps you diagnose issues faster, predict problems before they happen, and even draft your post-incident reports. This isn't science fiction; it's what our Lead Network Engineers are already starting to use, and we want you to be part of it.

Automated Log Triage & Correlation

AI can chew through millions of logs from your firewalls, routers, and switches, automatically spotting related events and giving you a single, intelligent summary. Instead of you sifting through 50 separate alerts, it'll tell you: 'User X failed VPN login 5 times then successfully logged in from a new IP.' It's like having a super-fast, tireless junior analyst.

Predictive Bandwidth Saturation

Forget being reactive. AI analyses historical bandwidth use on key internet and WAN circuits, then proactively alerts you: 'The London office circuit is projected to hit 90% capacity in 45 days based on current growth.' This means you can upgrade before users even notice a slowdown, preventing those 'internet is slow' tickets.

Intelligent Troubleshooting Assistant

Imagine an AI tool that's read every piece of our internal documentation, every past ticket, and every vendor manual. You can ask it, 'What are the steps to troubleshoot OSPF adjacency issues on a Cisco ISR 4K?' and get a concise, step-by-step checklist, compiled from the best available info. It's your personal, always-on expert.

Automated Post-Incident Report (PIR) Drafts

After a major incident, the last thing you want to do is spend hours writing a PIR. AI can pull data from Slack/Teams channels, ServiceNow ticket timelines, and monitoring system alerts to automatically generate a draft PIR. It'll include a precise timeline of events, key actions taken, and who was involved, saving you precious time.

The honest bit

You’ve started things before

Most of them were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.

There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.

And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.

What it costs

Less than one coaching session. Every month.

A single career-coaching hour costs more than a month of this, and it ends when the hour does. Zavmo doesn't. It's £70 a month, about £2.30 a day, for a companion that knows a Lead Network Engineer, works on the job you actually do, and keeps going at your pace rather than a timetable's.

Stay in the field you know and move sideways rather than up.

If you leave this industry

The skills you'll gain here – deep technical expertise, problem-solving, leadership, and architectural design – are highly transferable. You could move into network consulting, become a Solutions Architect for a major cloud provider or network vendor, or even transition into broader infrastructure or security leadership roles in almost any industry. Good network engineers are always in demand.
