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.

Project On-Time Delivery
The percentage of network projects (e.g., new office builds, core network upgrades) that you lead and deliver within the agreed schedule and budget.
Target · 90% of projects delivered on time and within budget.

Leading the deployment of a new data centre interconnect, you get it live by the target date of 15 January, within the allocated £100K budget.

Mean Time to Resolution (MTTR) for Major Incidents
How quickly you diagnose and resolve P1/P2 network incidents when acting as an escalation point.
Target · <30 minutes for P1 incidents, <60 minutes for P2 incidents (after initial triage by NOC).

Reduction in Recurring Incidents
The percentage decrease in repeat incidents caused by the same underlying network issue, thanks to your root cause analysis and preventative measures.
Target · 20% year-over-year reduction in recurring network incidents.

After a series of intermittent VPN connection drops, you identify an MTU mismatch, implement a fix, and track zero repeat incidents for 6 months.

Change Success Rate
The percentage of network changes (configurations, upgrades) you implement that are successful on the first attempt, without causing new issues or requiring rollbacks.
Target · >99.5% for all changes you lead.

You implement a complex BGP routing policy change across 10 core routers, and it goes live flawlessly, with no service impact or need for a rollback.

5Would you like it

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

What people enjoy
Solving Complex Puzzles

You get a real kick out of troubleshooting obscure network issues, digging through logs and packet captures until you find that one misconfigured ACL or a subtle BGP peering problem. It's like being a detective for data.

Spending three hours on a Wireshark capture to pinpoint why a specific application's traffic is seeing intermittent delays, eventually finding a 'hairpinning' issue on a firewall.

Building Resilient Systems

You love designing and implementing network solutions that just *work*, even when things go wrong. The idea of building something truly robust and highly available really appeals to you.

Designing and deploying a new multi-site VPN solution with redundant links and automatic failover, knowing it'll keep critical business traffic flowing even if one site goes down.

Mentoring & Knowledge Sharing

You enjoy helping junior engineers understand tricky concepts, reviewing their configurations, and guiding them through their first major incident. Seeing them 'get it' is really satisfying.

Sitting down with a new engineer to walk them through the intricacies of OSPF area design, explaining not just the 'how' but the 'why' behind it.

What frustrates people
  • The 'It's always the network' blame game: You'll spend hours proving network innocence for an application issue that turns out to be a database problem.
  • Inheriting a 'house of cards' network: Dealing with poorly designed, undocumented infrastructure where you're terrified to touch anything for fear of bringing it all down.
  • Vendor support runaround: Spending days arguing with a vendor's support team who insist their hardware is fine, only for them to eventually admit it's a known bug.
  • Change freeze exceptions: The 'absolutely critical, business-stopping emergency' change request that lands at 4 PM on a Friday before a long weekend.
  • Cabling archaeology: Trying to trace a single cable through a rack that looks like a rat's nest, with unlabeled patch panels from three different corporate acquisitions.
What this role does not give you
  • A purely strategic, hands-off role: You'll still be getting your hands dirty with configurations and troubleshooting.
  • A low-pressure, predictable environment: Expect urgent requests and occasional out-of-hours work when things go wrong.
  • Complete autonomy from process: We have change control and MOPs for a reason; you'll need to follow them.

6Who you work with

This role directly impacts the stability, performance, and security of our entire telecoms infrastructure. Your work ensures our internal systems, customer-facing applications, and voice/data services are always available. You're essentially the guardian of our digital highways, making sure traffic flows efficiently and securely.

Inside the business
  • Lead Telecoms Infrastructure Engineer (your manager)
  • Internal Project Managers (for new initiatives)
  • Cyber Security Team (for policy and compliance)
  • Application Development Teams (for connectivity requirements)
  • IT Operations Centre (for incident escalation)
Outside the business
  • Telecoms Vendors (Cisco, Juniper, Palo Alto)
  • Internet Service Providers (ISPs)
  • Cloud Providers (AWS, Azure networking teams)
  • Managed Service Providers (for specific outsourced functions)

7What you need before you start

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

  • At least 5 years of hands-on experience designing, implementing, and troubleshooting complex enterprise or service provider networks.
  • Proven ability to lead network projects from conception to completion, managing technical aspects and timelines.
  • Demonstrable experience with at least two major network vendor platforms (e.g., Cisco, Juniper, Palo Alto).
  • Strong understanding of network automation principles and practical experience with scripting (Python) or configuration management tools (Ansible).
  • Experience acting as an escalation point for critical network incidents, performing deep-dive root cause analysis.
  • Solid grasp of network security fundamentals, including firewalls, VPNs, and segmentation concepts.

8What to practise next

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

Network Programmability & API Integration

Traditional CLI-driven network management is becoming a bottleneck. Future networks will be managed programmatically via APIs, integrating with orchestration platforms and CI/CD pipelines. This is how we'll achieve true agility and scale.

RESTful APIs for Network Devices · NetDevOps Principles · Data Models (YANG, OpenConfig) · Orchestration Tools (e.g., Ansible, Terraform, Nornir)

  • This month: Pick a network device with an API (e.g., Meraki, a virtual router) and write a Python script to query its status or make a simple config change.
  • Month 2: Explore a NetDevOps course or online lab, focusing on using Git for network config management and basic CI/CD pipelines.
  • Month 3: Propose and implement a small automation project using an orchestration tool to manage a repetitive task (e.g., VLAN creation across multiple switches).
  • Month 4: Get involved in discussions about our future network automation strategy, bringing your insights from hands-on experimentation.

Quick win: Start using Python's 'requests' library to interact with any network device APIs you have access to. Even simple 'GET' requests to pull data can be a powerful first step.

Cloud-Native Networking & Security

Our infrastructure is increasingly hybrid and multi-cloud. Understanding how networking and security work natively within cloud platforms (AWS, Azure, GCP) is no longer optional; it's fundamental to designing and operating our future network.

Cloud VPC/VNet Design & Best Practices · Hybrid Connectivity (Direct Connect, ExpressRoute, VPNs) · Cloud Security Groups & Network ACLs · Cloud Load Balancers & DNS

  • This month: Complete an AWS Certified Solutions Architect - Associate or Azure Administrator Associate course, focusing on the networking modules.
  • Month 2: Spin up a small lab environment in AWS or Azure, deploying a multi-tier application and configuring its networking and security.
  • Month 3: Work with our cloud teams to troubleshoot a hybrid connectivity issue or review a new cloud network design.
  • Month 4: Propose an optimisation or security enhancement for one of our existing cloud network deployments.

Quick win: Familiarise yourself with the AWS or Azure networking console. Just clicking around and understanding where things are (VPCs, subnets, route tables) is a great start.

9Staying current once you are in

What people here do to keep up
  • Regularly engage with industry blogs, forums (e.g., Packet Pushers, r/networking), and online communities to stay current on new technologies and best practices.
  • Attend virtual or in-person industry conferences (e.g., Cisco Live, Juniper NXTWORK, Network Field Day) to network and learn about emerging trends.
  • Maintain a home lab or use cloud lab environments to experiment with new network configurations, automation scripts, and protocols without impacting production.
  • Actively seek out opportunities to mentor junior colleagues and participate in internal knowledge-sharing sessions.
  • Contribute to open-source network automation projects or develop your own tools to solve common problems.

Working with AI

Where AI is starting to help

Let's be real: a lot of network engineering involves repetitive tasks, digging through mountains of logs, and drafting documentation. But what if you could offload a significant chunk of that to AI? We're not talking about replacing you; we're talking about making you ridiculously more productive.

Our AI Productivity Hub is designed specifically for Telecoms Infrastructure Engineers. It's a suite of tools and integrations that help you automate the mundane, accelerate troubleshooting, and free you up to focus on the truly strategic, complex network challenges.

AIOps Root Cause Analysis

Imagine an outage: instead of manually logging into 20 different systems, our AIOps platform ingests all logs, metrics, and packet data. It then automatically correlates thousands of events to pinpoint the root cause in minutes. You get a diagnosis, not just a pile of alerts.

Predictive Capacity Planning

AI analyses historical bandwidth use and business growth. It'll proactively alert you three months *before* a specific circuit is likely to get saturated, letting you upgrade it before users even notice a slowdown. No more last-minute scrambles.

AI-Assisted MOP Generation

Need a detailed Method of Procedure for a complex change? Our AI assistant drafts it for you. It pulls from vendor best practices, our internal docs, and past successful changes, generating config snippets, validation steps, and rollback commands. You just review and refine.

Automated Incident Reporting

After an incident, AI summarises the technical timeline, all the alerts, and the resolution steps from Slack, Jira, and your monitoring tools. It then drafts a clear, business-friendly post-mortem report, saving you hours of tedious documentation.

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 Senior Telecoms Infrastructure Engineer, 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 13 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 Senior Telecoms Infrastructure Engineer: personal to you, and it still counts. The first steps are free.
