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
Network Design Changes Follows pre-approved designs; escalates any deviations. Proposes minor design tweaks for routine problems; consults senior staff. Designs and implements complex network solutions within architectural guidelines; consults Lead/Manager on major strategic shifts.
Budget Allocation (Project Specific) No budget authority; requests equipment/software via supervisor. Recommends purchases up to £1K; requires manager approval. Recommends project budgets up to £5K; requires manager approval.
Vendor Selection (Technical Assessment) No involvement. Provides feedback on specific product features. Evaluates technical capabilities of vendor solutions; provides recommendations to Lead/Manager.
Team Mentorship & Development Receives mentorship. Offers informal help to new joiners. Formally mentors 1-2 junior team members; provides regular technical guidance.

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.

Project Delivery Rate
Percentage of assigned network design and implementation projects completed on schedule and within budget.
Target · 90% of projects delivered on-time and on-budget.

Delivered the new office network build-out three days ahead of schedule and £5K under budget, including all required security configurations and documentation.

Mean Time To Recovery (MTTR) Contribution
Your direct impact on reducing the time it takes to restore service after a major network incident, particularly for issues related to your designs.
Target · Reduce MTTR for incidents related to new designs by 15% year-over-year.

After a core switch failure, your pre-designed failover procedures and clear documentation meant service was restored in 25 minutes, down from a typical 45 minutes for similar incidents.

Network Availability for Critical Services
Maintaining high uptime for the network segments and services you've designed or are directly responsible for.
Target · Achieve 99.99% (four nines) availability for critical production network segments.

Ensured the data centre fabric, which you designed, maintained 99.995% uptime over the last quarter, exceeding the target and preventing any application outages due to network issues.

Automation Adoption Rate
The percentage of routine network tasks (e.g., config changes, health checks) that are automated using scripts or IaC, driven by your initiatives.
Target · Increase automated network operations by 20% in the next 12 months.

Introduced Ansible playbooks for 30 new device configuration tasks, reducing manual effort by roughly 10 hours per week across the team and cutting human error significantly.

Technical Standard Setting & Adherence
How effectively you establish, document, and champion network design and operational standards, and ensure the team follows them.
  • You'll be the one writing the new network architecture documents, getting buy-in from the wider team, and then seeing those standards actually applied in new deployments. People will ask you for advice on best practices, and your documentation will be the go-to resource. We'll see fewer 'one-off' solutions and more consistent, robust designs.
Mentorship & Team Development
Your ability to guide and develop junior and mid-level network administrators, helping them grow their technical skills and problem-solving abilities.
  • You'll be regularly doing code reviews, pair-programming, and explaining complex concepts to team members. We'll see junior admins coming to you for advice before escalating to management. A good sign is when one of your mentees successfully takes on a more complex project or gets promoted, directly crediting your guidance.
Proactive Problem Identification
Your knack for spotting potential network issues or architectural weaknesses before they become major problems, then proposing and implementing solutions.
  • You're not just reacting to alerts
  • you're analysing trends, reviewing logs, and suggesting architectural tweaks to prevent future outages. You might spot a looming capacity issue on a WAN link or a security gap in a firewall policy and get ahead of it. Your proposals will often lead to projects that improve network resilience or performance before anyone else even noticed a problem.
Cross-Functional Collaboration & Influence
How well you work with other teams (like Security, Applications, and Cloud) to design integrated solutions and get everyone on the same page.
  • You'll be regularly invited to planning meetings for new applications or cloud migrations, not just as a network resource, but as a key design voice. You'll be able to explain complex network concepts to non-technical folks and get them to agree to the right approach. When there's a disagreement between teams, you're the one who can bridge the gap and find a solution that works for everyone.

7Would you like it

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

What people enjoy
Solving Complex Puzzles

You'll spend hours troubleshooting a tricky BGP peering issue, not because you have to, but because you genuinely enjoy the intellectual challenge of unravelling a complex network problem. The 'aha!' moment when you find the solution is what keeps you going.

Spending a Saturday morning voluntarily researching a new routing protocol feature that could solve a persistent performance issue, just for the satisfaction of understanding it.

Building Robust Systems

You get a real kick out of designing a network segment that's highly available, secure, and performs flawlessly. You enjoy the process of architecting something from scratch and seeing it work exactly as intended, knowing it's going to support critical business functions.

Successfully deploying a new data centre network fabric that performs 20% faster than the old one, with built-in redundancy that has already prevented two potential outages.

Technical Leadership & Mentorship

You enjoy being the person others come to for technical guidance and advice. You're motivated by helping junior team members understand tricky concepts or unsticking them from a difficult problem, knowing you're helping them grow.

One of your mentees successfully leads a medium-sized network project after you've spent months guiding them through the design and implementation phases.

What frustrates people
  • Being the default scapegoat for every IT problem, regardless of the actual root cause.
  • The constant need for after-hours work for critical changes and incident response.
  • Dealing with poorly documented legacy systems and technical debt.
  • Stakeholders who don't understand network complexity but demand instant fixes.
  • The struggle to get budget approval for essential upgrades, only to react to a failure later.
What this role does not give you
  • A strict 9-to-5 schedule with no out-of-hours commitments.
  • A completely greenfield environment with no legacy systems to support.
  • A role where you only focus on design and never have to get your hands dirty with troubleshooting.
  • An environment where every single design decision is immediately approved and funded without challenge.

8Who you work with

This role directly shapes the reliability, performance, and security of our entire network. Your decisions here directly affect how quickly our applications run, how safe our data is, and how much downtime we experience. Get it right, and the business hums along; get it wrong, and you're looking at significant operational disruption and potential financial losses. You're effectively building the roads and bridges that our entire digital business travels on.

Inside the business

10What to practise next

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

Advanced Multi-Cloud Networking & Interconnect

Critical within 12 months. Most organisations are no longer single-cloud. You'll need to design seamless, secure, and performant network connectivity between multiple cloud providers and our on-premises data centres. This is where the complexity really ramps up.

Cloud Native Network Services · Multi-Cloud Network Overlay · Hybrid Cloud Network Security · Cloud Network Cost Optimisation

  • This month: Deep-dive into the advanced networking features of a second cloud provider (e.g., if you know AWS, learn Azure).
  • Next quarter: Design a hypothetical hybrid cloud network architecture for a new application, considering resilience and security.
  • Month 4-6: Explore multi-cloud networking platforms and their capabilities, perhaps deploying a trial in a lab environment.
  • Month 7-9: Present a strategy for optimising our current cloud network spend without compromising performance or security.

Quick win: Review our current cloud network architecture for any obvious single points of failure or inefficient routing. Look for opportunities to consolidate VPNs or optimise egress traffic costs.

Network Automation Pipeline & CI/CD

Important within 12 months. It's not enough to just write scripts; you'll need to integrate network automation into full CI/CD pipelines, treating network configurations like application code. This means version control, automated testing, and continuous deployment for network changes.

Git-based Network Configuration Management · Automated Network Testing · Network Change Orchestration · Network State Validation

  • This month: Set up a personal Git repository for your network scripts and configurations.
  • Next quarter: Learn the basics of a CI/CD tool (e.g., GitLab CI/CD) and try to automate a simple network health check.
  • Month 4-6: Explore network testing frameworks and integrate automated tests into a small configuration deployment pipeline.
  • Month 7-9: Propose a plan to implement a full CI/CD pipeline for a critical network segment, including automated validation.

Quick win: Start by putting all your existing Ansible playbooks and Python scripts under version control in Git. Even without a full pipeline, this is a massive step forward for collaboration and change tracking.

11Staying current once you are in

What people here do to keep up
  • Regularly participate in industry forums and online communities (e.g., Packet Pushers, Reddit's r/networking) to stay current on emerging technologies and best practices.
  • Attend virtual or in-person network conferences (e.g., Cisco Live, Juniper Elevate, AWS re:Invent) to learn from experts and network with peers.
  • Contribute to open-source network automation projects or maintain a personal lab environment to experiment with new tools and protocols.
  • Pursue advanced certifications in areas like cloud networking, network security, or automation to deepen your specialisation.
  • Take online courses or read technical books on topics like Python for network automation, advanced BGP, or data centre fabric design.

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 Observability & AIOps Integration

Critical within 12 months. As networks get more complex and distributed (cloud, edge), traditional monitoring isn't enough. We need to move towards holistic observability and use AI to spot patterns and predict issues before they impact users. Competitors are already using this to reduce MTTR and proactively fix problems.

  • Telemetry Data Collection
  • Machine Learning for Anomaly Detection
  • Root Cause Analysis Automation
  • Digital Experience Monitoring (DEM)

Zero Trust Network Architecture (ZTNA) Design

Critical within 6 months. The traditional 'trust but verify' perimeter model is dead. With remote work and cloud adoption, we need to implement 'never trust, always verify'. This isn't just a buzzword; it's a fundamental shift in how we secure access to resources, and frankly, it's already here.

  • Micro-segmentation
  • Identity-Centric Access
  • Context-Aware Policies
  • Least Privilege Access

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of network admin work can be a bit repetitive or just plain time-consuming. Imagine if you could offload some of that grunt work and focus on the really interesting stuff – the complex designs, the deep troubleshooting, the strategic planning. Good news: AI can help you do exactly that.

We're not talking about AI replacing you; we're talking about AI making you a superpower. For a Lead Network Administrator, this means using AI to automate config generation, predict outages before they happen, and quickly make sense of mountains of log data. It's about working smarter, not just harder.

Config Generation & Validation

Use AI assistants to whip up boilerplate configurations for new devices based on our established templates. Even better, AI can audit existing configs against security baselines (like CIS benchmarks) and instantly flag any deviations or potential 'fat-fingered' mistakes. This means fewer errors and faster deployments.

AIOps for Predictive Analysis

Imagine knowing a link is about to get saturated or a device is likely to fail before it actually happens. AIOps platforms ingest all that network telemetry data and use AI to predict future issues. This shifts your work from constantly reacting to outages to proactively preventing them, which is a game-changer.

Vulnerability & Doc Synthesis

Got a new CVE (Common Vulnerabilities and Exposures) report? Point an AI tool at it and your network inventory. Ask it to summarise the risk, identify exactly which devices are affected, and even outline the vendor's recommended mitigation steps. It's like having a security analyst and a research assistant rolled into one.

Outage Report Translation

After you've fixed a major incident, you've got a detailed technical timeline. Feed that into an AI model and ask it to generate a clear, non-technical executive summary for the CEO. It saves you ages trying to 'dumb it down' and ensures everyone gets the right message, fast.
