3What this role really is

A senior network support technician fixes complex network faults, finds the root cause, and gets systems back online.

4What you'd actually use

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

SolarWinds NPM / PRTG Advanced

Configuring new monitors, building custom dashboards, setting complex alert thresholds, and analysing performance trends to proactively identify issues or diagnose performance bottlenecks. You'll be using this to spot 'flapping ports' before they become a problem.

Wireshark Advanced

Using advanced filters, following TCP streams, reconstructing conversations, and identifying subtle protocol-level anomalies to diagnose complex connectivity or application performance issues. This is your go-to for deep-dive packet analysis.

ServiceNow / Jira Service Management Advanced

Designing incident/problem/change workflows, creating comprehensive knowledge base articles, and generating performance reports for the team. You'll be managing your own ticket queue but also helping to optimise the system for others.

Cisco IOS / Juniper Junos / FortiOS Advanced

Writing and deploying complex configurations for routers, switches, and firewalls (ACLs, BGP/OSPF peers, VPN tunnels). Performing OS upgrades and troubleshooting device-specific issues. You'll be comfortable with the command line on all these platforms.

Python (Netmiko, Paramiko) / Ansible Intermediate

Writing and maintaining Python scripts or Ansible playbooks to automate repetitive network device configuration tasks, compliance checks, and data gathering. You'll be looking for opportunities to automate away the boring stuff.

Confluence / Notion (with Lucidchart/Visio embeds) Advanced

Creating and maintaining detailed network diagrams, standard operating procedures (SOPs), and comprehensive RCA documents. You'll be the keeper of accurate network knowledge.

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
Incident Resolution (P1/P2) Escalates to L2/L3 after basic diagnostics. Follows runbooks for known issues. Independently troubleshoots and resolves routine P2/P3s. Escalates P1s and complex P2s to L3. Leads the resolution of all P1/P2 incidents, coordinating resources and communicating status. Decides on immediate actions and rollback strategies.
Network Configuration Changes Executes pre-approved, scripted changes under direct supervision. Performs routine configuration changes (e.g., VLAN assignment) within established guidelines, with peer review. Designs and implements complex configuration changes (e.g., new ACLs, routing protocol adjustments), writes and reviews change requests, and performs peer review for junior technicians. Consults Lead on architectural impact.
Tool Selection & Methodology Uses approved tools and follows defined troubleshooting methodologies. Chooses appropriate tools from the approved stack for routine problems. Adapts standard methodologies. Selects the best troubleshooting tools and methodologies for novel or complex issues. May propose new tools for evaluation (under £5K) to the Lead Network Engineer.
Problem Management & RCA Documents symptoms and initial findings for recurring issues. Identifies recurring issues and contributes data to RCA efforts led by L3/L4. Leads the Root Cause Analysis for significant recurring problems, identifies permanent solutions, and proposes these to Network Engineering. Documents findings and recommendations.

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.

Mean Time to Resolution (MTTR) for Escalated Incidents
The average time it takes to fully resolve P1 and P2 incidents that have been escalated to you.
Target · < 2 hours for P1, < 4 hours for P2

If a critical application goes down and it's escalated to you, we'd expect it back up and stable within a couple of hours. This isn't just about the fix, but the complete resolution, including documentation.

Reduction in Recurring Incidents
The percentage decrease in P1/P2 incidents that have happened before, indicating effective problem management.
Target · 15% Quarter-over-Quarter (QoQ)

If we had 10 P1 incidents related to a specific VPN tunnel in Q1, we'd want to see that drop to 8 or fewer in Q2 because you've identified and fixed the underlying cause, not just the symptom.

Change Success Rate
The percentage of network changes you implement that go smoothly without causing new incidents or requiring rollbacks.
Target · > 98%

If you're deploying a new firewall rule or upgrading switch firmware, it should work as expected the first time, without breaking anything else. A successful change means no unexpected P3s popping up afterwards.

Knowledge Base Contribution & Quality
The number of new or updated knowledge base articles (SOPs, runbooks, troubleshooting guides) you create, and their usefulness to the team.
Target · 2-3 new/major updates per month, with a 4/5 average rating from users

You might write a detailed guide on troubleshooting 'flapping ports' that helps junior technicians resolve these issues independently, saving everyone time and reducing escalations.

Effective Escalation & Collaboration
How well you work with other teams and senior engineers when an issue goes beyond your scope, or when you need their input.
  • You're clearly articulating the problem, the steps you've already taken, and what help you need. Other teams will tell us you're easy to work with and provide useful information. You're not just 'throwing it over the fence' but actively driving the resolution with others. You'll get positive feedback from the Lead Network Engineer on your ability to work with the Network Engineering team to get design changes implemented.
Mentorship & Team Development
The impact you have on the skills and confidence of junior network technicians.
  • Junior team members will come to you for advice and feedback, and they'll show measurable improvement in their troubleshooting skills. You'll be running informal 'lunch and learn' sessions or doing regular code reviews for automation scripts. Your manager will see a decrease in L1/L2 errors on issues you've helped them with.
Proactive Problem Identification
Your ability to spot potential issues before they become major incidents, often by noticing subtle patterns or anomalies.
  • You're regularly flagging potential risks based on monitoring data or recurring minor alerts. You'll be proposing and leading small projects to address these risks, like optimising a specific routing path or updating an old firmware, before it becomes a P1. You'll catch the 'flapping port' before it causes a 'broadcast storm'.
Documentation Quality & Adherence
The clarity, accuracy, and completeness of your documentation for incidents, changes, and knowledge base articles.
  • Your incident reports are comprehensive, detailing the root cause and resolution steps without ambiguity. Other team members can easily follow your change documentation. Network diagrams you create are up-to-date and accurate, reflecting the actual state of the network.

7Would you like it

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

What people enjoy
Solving Complex Puzzles

You get a real buzz from taking a tangled, seemingly impossible network problem, breaking it down, and finding the elegant solution. That feeling when you finally pinpoint the 'split-brain' issue after hours of digging? That's what keeps you going.

You spend a day troubleshooting intermittent connectivity for a specific application, digging through firewall logs, packet captures, and routing tables, only to discover a subtle MTU mismatch that was causing fragmentation. The satisfaction of that 'aha!' moment is your fuel.

Making a Tangible Impact

You like to see your work directly affect the business. When you fix a critical network issue, you know you've just saved the company money, allowed sales to close deals, or kept our customers happy. Your efforts aren't abstract; they're concrete.

During a major outage, your quick diagnosis and resolution gets the e-commerce platform back online, preventing hundreds of thousands of pounds in lost sales. You get a direct thank you from the Head of Sales, and that means something.

Continuous Learning & Mastery

You're driven by the desire to truly master network technologies. You want to understand the protocols at a deep level and keep up with the latest advancements. You're always looking for a new challenge or a new skill to add to your toolkit.

You spend your evenings experimenting with Ansible playbooks for network automation, even though it's not strictly required yet. You're always reading industry blogs, watching webinars, and trying to get your hands on new gear to learn its quirks.

What frustrates people
  • The 'It's a Network Problem' Default: Being the first to be blamed for any application slowness, and spending 80% of your time proving the network is fine before the application team starts investigating their code.
  • Undocumented Changes: A server admin 'quickly' changes a server's IP address without telling anyone, generating a P1 ticket that takes an hour to diagnose what should have been a 2-minute documentation check.
  • On-Call Fatigue: Getting paged at 3 AM because a non-critical, remote-office printer went offline and the automated alert was configured too sensitively. Or worse, because someone 'fat-fingered the config' on a test device.
  • Change Management Rigidity: Knowing a five-minute fix for a problem but having to wait 48 hours for the Change Advisory Board (CAB) to approve your emergency change request, even when it's obvious.
  • Legacy Gear: Trying to keep the network running on a shoestring budget with 10-year-old switches that lack modern features and are one power surge away from failure. And yes, sometimes we still use that old system.
  • Vague User Reports: Wasting hours on tickets that just say 'The internet is slow' with no additional context, user location, or specific application mentioned. It's like being asked to find a needle in a haystack without knowing what a needle looks like.
What this role does not give you
  • A quiet, predictable 9-to-5 schedule – outages don't care about your plans.
  • The chance to always work on brand-new, cutting-edge tech; you'll spend a fair bit of time keeping older systems alive.
  • A role where you only ever build new things; a lot of your time will be spent fixing, maintaining, and optimising existing infrastructure.
  • A job where you're always thanked for your efforts; sometimes, keeping things running smoothly just goes unnoticed.

8Who you work with

This role directly impacts the uptime and performance of our entire network. You're the last line of defence before major outages become prolonged. Your ability to quickly diagnose and resolve complex issues minimises business disruption, protects revenue, and maintains our reputation. You also play a key part in improving our network's long-term health by identifying recurring problems and suggesting permanent fixes.

Inside the business
  • Network Operations Team (L1/L2 Technicians)
  • Network Engineering Team (L4+ Engineers)
  • Server & Infrastructure Teams
  • Application Development Teams
  • Service Desk & End User Computing Teams
  • Security Operations Centre (SOC)
Outside the business
  • Internet Service Providers (ISPs)
  • Hardware Vendors (Cisco, Juniper, Aruba)
  • Software Vendors (SolarWinds, ServiceNow)
  • Managed Service Providers (MSPs) for specific services

9What you need before you start

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

  • Solid 5+ years of hands-on experience in a dedicated network support or network operations role, not just general IT support.
  • Demonstrable experience leading the resolution of P1/P2 network incidents from start to finish.
  • Proven ability to perform Root Cause Analysis (RCA) and implement permanent fixes for recurring network issues.
  • Strong understanding and practical experience with advanced routing protocols (OSPF, BGP) and switching technologies (VLANs, STP, HSRP/VRRP).
  • Experience configuring and troubleshooting enterprise-grade firewalls (e.g., Fortinet, Cisco ASA/FTD, Palo Alto) and VPN solutions.
  • A track record of creating clear, comprehensive network documentation and knowledge base articles.
  • Experience with network automation scripting (e.g., Python with Netmiko/Paramiko, Ansible) or a strong desire to learn and apply these skills.
  • Excellent communication skills – you can explain a 'broadcast storm' to a non-technical person without them glazing over.

10What to practise next

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

Advanced Network Security Troubleshooting

Cyber threats are constantly evolving, and the network is often the first line of defence. You'll need to go beyond basic firewall rules and understand complex attack vectors, intrusion detection, and how to troubleshoot security incidents at the network layer. This isn't just about fixing; it's about defending.

Deep packet inspection (DPI) and intrusion prevent · Security Information and Event Management (SIEM) i · Troubleshooting DDoS mitigation techniques · Understanding common attack patterns (e.g., port s · Zero Trust Network Access (ZTNA) principles and th

  • This month: Familiarise yourself with our current firewall policies and how to interpret their logs for security events. Understand what constitutes a 'security incident' from a network perspective.
  • Next 3 months: Research common network attack vectors. Try to simulate a simple port scan in a lab environment and see how our network devices respond.
  • Month 4-6: Work closely with the SOC team on any network-related security incidents. Understand their tools and how you can provide valuable network data.
  • Month 7-9: Explore advanced features of our firewalls, like IPS/IDS capabilities. Learn how to tune them to reduce false positives.
  • Month 10-12: Take a dedicated course on network security fundamentals or a certification like CompTIA Security+ or Fortinet NSE 4.

Quick win: Start reviewing firewall logs daily, looking for unusual patterns or blocked connections that might indicate a probing attempt. It's a habit that pays off.

Software-Defined Networking (SDN) & SD-WAN Concepts

Traditional network management is too rigid. SDN and SD-WAN are changing how we deploy, manage, and optimise our wide area networks. While you might not be designing these, you'll certainly be troubleshooting them and needing to understand their operational model.

Separation of control plane and data plane · Centralised network management and orchestration · Application-aware routing and policy enforcement i · Overlay and underlay networks · Troubleshooting common SD-WAN performance issues

  • This month: Read up on the basic concepts of SDN and SD-WAN. Understand why companies are moving to these technologies.
  • Next 3 months: Research popular SD-WAN vendors (e.g., Cisco Viptela, Fortinet FortiWAN, VMware VeloCloud). Watch some introductory videos.
  • Month 4-6: If we have an SD-WAN deployment, get familiar with its management console. Understand how to check application performance and path selection.
  • Month 7-9: Work with the Network Engineering team on any SD-WAN related projects. Understand how changes are deployed and how to troubleshoot connectivity.
  • Month 10-12: Look for opportunities to apply your existing routing and switching knowledge to the new SD-WAN paradigm. How do OSPF and BGP interact with the SD-WAN overlay?

Quick win: Watch a few YouTube videos explaining SD-WAN in 10 minutes. It'll give you a good mental model for when you encounter it in tickets.

11Staying current once you are in

What people here do to keep up
  • Regularly engage with network engineering blogs, industry forums (e.g., Packet Pushers, EtherealMind), and vendor documentation to stay current with new technologies and best practices.
  • Actively participate in internal knowledge-sharing sessions, presenting on complex incidents you've resolved or new techniques you've learned.
  • Set up a home lab environment (even virtualised ones using GNS3 or EVE-NG) to experiment with new configurations, protocols, and automation scripts without impacting production.
  • Attend relevant webinars or virtual conferences to keep your skills sharp and understand emerging trends in network operations and security.
  • Seek out opportunities to cross-train with other infrastructure teams (e.g., server, cloud) to broaden your understanding of the wider IT ecosystem.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of network support work is repetitive, time-consuming, and frankly, a bit of a grind. But what if you could offload some of that to AI? We're not talking about replacing you; we're talking about giving you a superpower. Imagine having more time for the really interesting, complex problem-solving – the stuff you actually enjoy.

Our AI Productivity Hub is all about giving our Network Support Technicians the tools to work smarter, not harder. For a Senior Network Support Technician, this means less time sifting through logs manually and more time actually fixing things, designing better solutions, and mentoring the team. It's about amplifying your expertise, not diminishing it.

Predictive Failure Analysis

Imagine an AI-powered log analyser (like Splunk or Datadog) constantly chewing through all our syslog, SNMP, and NetFlow data. It's not just alerting on thresholds; it's spotting subtle patterns and anomalies that usually happen before a hardware failure or a link gets saturated. It'll create a predictive ticket for you, giving you a heads-up before an outage even thinks about happening. That's proactive, not just reactive.

Accelerated Root Cause Analysis (RCA)

During an outage, you're usually drowning in alerts from firewalls, switches, servers, and applications. An AIOps platform can ingest all that noise, correlate events across the entire timeline, and instantly suggest the most likely point of failure. It cuts through the chaos, helping you get to the 'it's a DNS issue' or 'broadcast storm' diagnosis much, much faster. Think of it as your super-intelligent incident assistant.

Smart Configuration Generation

Need to roll out a new switch or update a firewall? Instead of starting from scratch or digging through old configs, you can use a specialised AI assistant. Just prompt it: 'Generate a secure baseline config for a Cisco C9300 switch on IOS-XE 17.6, including port security for user ports 1-20, a voice VLAN, and 802.1x settings.' The AI gives you a solid template that you can quickly review, tweak, and deploy, saving you loads of manual typing and potential 'fat-fingered' errors.

Plain-English Outage Comms

During a P1 incident, the last thing you want to do is spend ages drafting communications for non-technical stakeholders. Just paste your technical ticket updates into an AI model and ask it to 'Draft a status update for a non-technical business audience.' It'll translate jargon like 'BGP peering session dropped' into 'We've lost our primary internet connection; we are failing over to the backup circuit now,' saving you precious minutes and ensuring clear communication when it matters most.
