1What this role really is

This isn't just about keeping the lights on; it's about making sure our network isn't just working, but absolutely flying. You'll be the person who figures out why that critical application is a bit sluggish on Tuesdays and then designs a fix that actually sticks. We're talking about shaping the network's future, not just reacting to its past. It's a proper hands-on leadership role, where you'll get to build, mentor, and really make your mark on how our systems perform.

2What you'd actually use

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

Datadog / LogicMonitorExpert

You'll be building custom dashboards, configuring complex alert triggers using multiple data sources (not just out-of-the-box stuff), and writing custom scripts to pull specific metrics from network devices for deep-dive analysis and proactive monitoring. This is where you'll spot those 'chasing ghosts' before they become real problems.

Wireshark (Expert)Expert

You'll be writing advanced capture and display filters, reconstructing TCP streams to understand application behaviour, analysing protocol handshakes in-depth, and using command-line tools (like tshark) for automated analysis of large packet captures. This is your scalpel for network forensics.

Python (Netmiko/NAPALM)Advanced

You'll be writing custom Python scripts to automate complex, multi-step network tasks, pull operational data via APIs for reporting, and perform configuration validation across hundreds of devices. This is how we make our network more efficient and less prone to human error.

Ansible (Advanced)Advanced

Beyond just running playbooks, you'll be designing and writing complex Ansible playbooks and roles for pushing standardised configuration changes, managing network device inventory, and orchestrating larger automation workflows. You'll also be integrating Ansible with other systems for a more cohesive automation strategy.

Splunk (SPL) / ELK Stack (Lucent)Advanced

You'll be writing complex search queries to correlate events across multiple device types (firewalls, routers, servers). This involves building custom dashboards and alerts for proactive threat detection and performance monitoring, helping us identify issues before they impact users. You're essentially a detective, using logs as your clues.

GNS3 / EVE-NG (Advanced)Advanced

You'll be creating complex, multi-vendor simulations of entire production environments in a lab setting. This is crucial for validating major architectural changes, testing BGP routing policies, or modelling failure scenarios *before* they ever touch our live network. It's your playground for 'what if' scenarios.

3What 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 choice	Coming in	Where you are now	The step above
Technical Design & Implementation	Follows prescribed designs; escalates any deviations.	Chooses implementation approach for routine designs; consults on complex variations.	Designs and implements solutions within a defined workstream; consults on architectural impact.
Project Scope & Timelines	Executes tasks within given timelines; reports delays.	Manages project segments; proposes minor timeline adjustments to manager.	Owns workstream timelines; makes recommendations for project-level changes.
Vendor Selection & Tooling	Uses approved tools; reports issues with tools.	Recommends specific tools for routine tasks within existing budget.	Evaluates and recommends new tools for specific workstream needs (up to £5K spend).
Team Mentorship & Development	Seeks guidance from senior colleagues.	Provides informal guidance to new joiners.	Mentors 0-2 junior engineers; provides technical feedback.

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.

Critical Application Latency Reduction

The average latency for our top 5 business-critical applications (e.g., CRM, ERP, core trading platform) across the network.

Target · Reduce by 10% Quarter-on-Quarter (QoQ)

If the CRM application's average network latency was 80ms last quarter, your target is to get it down to 72ms or less this quarter. We'd track this using our network monitoring tools and application performance metrics.

Network Mean Time to Resolution (MTTR)

The average time it takes to fully resolve network-related incidents, from detection to verified fix.

Target · Improve by 20% Annually

If our current MTTR for P1/P2 network incidents is 60 minutes, your goal would be to bring that down to 48 minutes or less over the next year, perhaps through better automation or diagnostic tools you've implemented.

Optimisation Project Delivery

The number of medium-to-large scale network optimisation projects (e.g., SD-WAN rollout, BGP tuning, cloud connectivity improvements) completed on time and within budget.

Target · Lead 3+ projects per year, 90% on-time/on-budget

Successfully delivering a new QoS policy across all branch offices by the end of Q2, and then rolling out a new cloud peering architecture in Q4, both without budget overruns or significant delays.

Network Capacity Utilisation Efficiency

The efficiency of how we use our network bandwidth, ensuring we're not over-provisioning or under-provisioning links.

Target · Maintain core network link utilisation between 40-70% during peak hours, with less than 5% packet loss.

Identifying a core link consistently running at 85% during peak times and designing a cost-effective upgrade or re-routing strategy before it becomes a bottleneck, keeping it within the target range.

Architectural Design Quality

How robust, scalable, and maintainable your network designs and optimisation proposals are, balancing performance with practical implementation and future needs.

Designs are peer-reviewed positively by Principal Architects. Solutions are deployed with minimal post-implementation issues. Your proposals clearly consider long-term operational impact and cost-effectiveness. You're seen as the go-to person for complex design challenges.

Technical Leadership & Mentorship

Your ability to guide, support, and develop junior and mid-level engineers, helping them grow their technical skills and problem-solving capabilities.

Junior engineers actively seek your advice and feedback. You regularly run workshops or knowledge-sharing sessions. You successfully mentor at least one junior engineer to a promotion within 18 months. Your team's overall technical proficiency improves under your guidance.

Cross-Functional Influence

How effectively you can get other teams (like Application Development, Security, or Operations) on board with your network optimisation strategies and changes.

You're proactively invited to early-stage project planning meetings by other departments. Your recommendations are frequently adopted by other teams without significant pushback. You can clearly explain complex network issues to non-technical audiences and get their buy-in for solutions.

Documentation & Knowledge Sharing

The clarity, accuracy, and completeness of the documentation you produce for designs, configurations, and troubleshooting guides, making it easier for everyone else.

Your documentation is consistently up-to-date and easy for other engineers to follow. New team members can quickly get up to speed on your projects using your guides. You contribute regularly to our internal knowledge base, making sure critical information is captured.

5Would you like it

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

What people enjoy

Solving Tough, Complex Puzzles

You get a real buzz from diving deep into a tricky network performance issue, piecing together data from various tools, and finally pinpointing the obscure root cause. The more challenging the problem, the more engaged you are.

Spending a full day tracing intermittent packet loss across a hybrid cloud connection, eventually discovering a subtle misconfiguration in a Transit Gateway route table that no one else spotted.

Building and Improving Things

You love designing new network architectures or optimising existing ones, seeing your plans go from whiteboard to production. There's satisfaction in knowing you've made a tangible difference to how our network performs.

Leading the design and implementation of a new SD-WAN overlay that significantly improves application performance for our remote offices, and then seeing the positive feedback from users.

Mentoring and Developing Others

You enjoy sharing your knowledge, guiding junior engineers through complex problems, and seeing them grow. You're happy to spend time explaining concepts or reviewing code, knowing it helps the whole team get better.

Helping a junior engineer debug a tricky BGP peering issue over several days, patiently explaining each step and guiding them to find the solution themselves, ultimately building their confidence.

What frustrates people

Being the 'network guy' blamed for every IT issue, regardless of the actual root cause.
Dealing with legacy network debt and outdated hardware that limits optimisation possibilities.
Slow, bureaucratic change management processes that delay critical fixes and improvements.
Lack of accurate documentation from other teams, leading to wasted troubleshooting time.
Stakeholders who expect 'magic packets'—instantaneous global connectivity despite the laws of physics.

What this role does not give you

A purely greenfield environment with no legacy systems to manage.
Complete control over all aspects of IT infrastructure (you'll need to influence, not dictate).
A quiet, predictable workload with no urgent, high-pressure incidents.
A role where you can avoid explaining complex technical details to non-technical people.

6Who you work with

This role directly shapes the performance, stability, and future direction of our network infrastructure. Your designs and optimisation projects will influence how quickly we can roll out new services, how resilient our systems are to outages, and how efficiently we use our network resources. Get it right, and you'll enable significant business growth; get it wrong, and you're looking at widespread service degradation and unhappy customers. It's a pretty big deal, frankly.

8What to practise next

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

Advanced Cloud Network Architecture & FinOps

Our cloud footprint is growing, and simply 'lifting and shifting' isn't cutting it anymore. We need to architect cloud networks for optimal performance, security, and cost-efficiency, understanding the nuances of each cloud provider's offerings. FinOps for cloud networking is becoming critical to avoid bill shock.

Multi-Cloud Connectivity Patterns · Cloud Network Security Posture Management · Cloud Network Cost Optimisation · Serverless & Container Networking

This month: Get certified in advanced networking for at least one major cloud provider (e.g., AWS Advanced Networking Specialty).
Month 2: Conduct a cost analysis of our current cloud network spend, identifying areas for optimisation.
Month 3: Design a multi-cloud connectivity solution for a hypothetical new application.
Month 4: Lead a workshop on cloud network FinOps best practices for the team.

Quick win: Review our current cloud network architecture for any obvious inefficiencies or over-provisioned resources today.

Programmable Networks (Intent-Based Networking)

The future of networking isn't just automation; it's about defining desired network behaviour (intent) and letting the network configure itself to achieve that. This requires understanding new controllers, APIs, and data models. It's a huge shift from command-line configuration.

Network Controllers (e.g., Cisco DNA Center, Juniper Contrail) · YANG Data Models & NETCONF/RESTCONF · Network Service Orchestration · Closed-Loop Automation

This month: Research a leading Intent-Based Networking (IBN) platform and its capabilities.
Month 2: Experiment with NETCONF/RESTCONF APIs on a virtual network device in your lab.
Month 3: Create a simple script to retrieve and modify network configuration using a YANG model.
Month 4: Develop a small proof-of-concept for an IBN use case relevant to our environment.

Quick win: Start familiarising yourself with the APIs of our existing network devices. Even small automation scripts are a step towards programmable networks.

9Staying current once you are in

What people here do to keep up

Regularly contributing to open-source network automation projects or sharing your scripts on platforms like GitHub.
Attending industry conferences (e.g., Cisco Live, Juniper NXTWORK, AWS re:Invent) to stay abreast of emerging technologies and best practices.
Participating in online forums or communities dedicated to network optimisation, automation, or cloud networking.
Subscribing to relevant technical journals, blogs, and newsletters to keep your knowledge current.
Presenting on technical topics internally or at local meetups, sharing your expertise and building your personal brand.

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 Observability Engineering

Traditional monitoring is no longer enough. We need to move beyond just 'is it up?' to 'why is it slow?' and 'what's the user experience like?'. This means integrating metrics, logs, and traces from every part of the network and correlating them with application performance data. Our competitors are already using this to reduce MTTR and proactively identify issues.

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

Network-as-Code & CI/CD for Network Changes

Manual network changes are slow, error-prone, and don't scale. The industry is rapidly moving towards treating network infrastructure like software, using version control, automated testing, and continuous deployment pipelines. If we don't adopt this, we'll be left behind in terms of agility and reliability.

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 (Optimisation) 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.

12The team that's yours

No two people are taught the same way. This is one-to-one, not one-to-many.

Zavmo is a hyper-personalised AI learning platform. Twelve virtual tutors, each with a different way of teaching, and one orchestration agent that picks the right one for the moment. So every single lesson is shaped around you, your role, and the way you learn. Not a course everyone sits through. A conversation built for you, and no one else.

…and nine more, matched to you after your first chat. Meet all twelve

Working with AI on the job

Working with AI

Where AI is starting to help

Imagine having a super-smart assistant who could handle the grunt work, leaving you free to focus on the really challenging, strategic network problems. That's what AI can do for a Lead Network Engineer (Optimisation) like you.

We're not talking about replacing your role; we're talking about making you incredibly more effective. AI tools are already transforming how we monitor, troubleshoot, and even design networks, giving you back precious hours every week. Here's how you could be using them:

Proactive Anomaly Detection

Forget sifting through endless logs and dashboards. Use AI/ML platforms (like Datadog AI or a custom ELK model) to automatically learn baseline network traffic patterns. The AI will flag statistically significant deviations – unusual traffic flows, sudden latency spikes – *before* they turn into major outages. This shifts you from reactive firefighting to proactive problem-solving, letting you fix issues before anyone even notices.

Root Cause Analysis Accelerator

When an incident does hit, feed logs from firewalls, routers, servers, and applications into an AI-powered correlation engine. This AI can instantly identify the most likely sequence of events across disparate systems that led to the failure. Instead of spending hours manually comparing logs, the AI points directly to the root cause, dramatically shortening your Mean Time To Resolution (MTTR) for complex, multi-system failures.

RFC & Vendor Doc Summariser

Faced with a complex configuration for a niche protocol or a 500-page vendor guide? Use a private AI assistant (like a local LLM or a secure cloud service) to summarise dense RFC documents or manuals. Ask specific questions like, 'Summarise the key differences in BGP community handling between Cisco IOS-XR and Juniper Junos,' and get immediate, actionable answers, saving you hours of tedious research.

Stakeholder Comms Generator

After a complex incident or a major optimisation project, use an AI tool to draft clear, concise post-mortems or executive summaries. Provide it with the technical timeline and key findings, and ask it to generate a business-friendly explanation of the impact, root cause, and remediation steps. This saves you significant time on administrative writing and ensures consistent, high-quality communication to non-technical stakeholders.

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 (Optimisation), works on the job you actually do, and keeps going at your pace rather than a timetable's.

Searching and planning stay free. You only pay when you start learning.
Your credits are yours. Regulated, and they don't vanish when a subscription ends.
Cancel any time and billing stops. No notice period, no minimum term.

Your path, personalised

You have the map. Walking it is the part we do together.

This route runs to 10 national skill standards. That is a real journey.

Zavmo shapes a learning experience as unique as you are. It fits how you learn, your pace and the work you already do. Every step stays benchmarked to recognised national standards. That’s the plan for becoming a Lead Network Engineer (Optimisation): personal to you, and it still counts. The first steps are free.

15Where to go from here

Other roles at Level 5

Same depth of qualification, different job. Useful if the work appeals but this particular role does not.

Other roles in Technical roles

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

If you leave this industry

The skills you'll gain here are highly transferable. You could move into cloud provider roles, become a network consultant for major enterprises, or even transition into roles focused on network security architecture, data centre design, or even application performance engineering, given your deep understanding of how applications interact with the network. The world needs good network optimisers, frankly.
