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
Routine Network Changes (e.g., adding a VLAN, configuring a switch port) Requires explicit approval from a Senior Engineer or Lead. All steps are reviewed. Can execute independently within established guidelines. Manager informed post-change. Independently executes and reviews changes for junior staff. May propose new standard operating procedures.
Complex Troubleshooting & Incident Response Escalates immediately after initial basic checks. Assists senior staff under direct guidance. Independently diagnoses and resolves Tier 2 incidents. Escalates to Senior Engineer if root cause is elusive or requires advanced tools. Leads diagnosis and resolution for Tier 2/3 incidents. Acts as technical escalation point. Mentors juniors during incidents. Makes critical real-time decisions to restore service.
Network Design & Architecture Contributes minor updates to existing diagrams. Follows existing designs. Proposes minor design improvements or modifications within existing architecture. Creates detailed implementation plans from high-level designs. Designs and implements solutions for specific workstreams (e.g., a new branch office network, firewall policy redesign). Makes recommendations on technology choices and best practices. Consults with Lead/Architect on strategic direction.
Budget Allocation for Small Projects/Tools No authority. Raises requests to manager. Can recommend tools or equipment up to £1K for project needs, requiring manager approval. Can recommend and justify purchases up to £5K for project-specific needs (e.g., testing equipment, specific software licenses), requiring manager approval. Influences larger budget discussions.

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.

Network Uptime for Critical Services
Ensuring our core network services (like internet access, internal applications, VoIP) are available when people need them.
Target · Achieve and maintain 99.99% ('four nines') availability across all critical network services.

If our internet connection was down for 5 minutes in a month, that's a 99.988% uptime, just under target. You'd need to figure out why and prevent recurrence.

Project Delivery Rate
How often you complete your assigned network projects (like a new firewall deployment or a core switch upgrade) on time and within the agreed scope.
Target · Deliver 90%+ of assigned projects on-time and on-budget.

You led the upgrade of our branch office routers; it was completed a week early and £2K under budget. That's a win.

Incident Reduction from RCA
Identifying the root cause of recurring network problems and implementing fixes to stop them happening again.
Target · Reduce the volume of recurring, high-impact incidents by 25% through root cause analysis (RCA) and proactive fixes.

We had 10 incidents of 'flapping ports' on the same switch last quarter. You found a faulty SFP, replaced it, and we've had zero incidents since. That's a 100% reduction for that specific issue.

Mean Time to Resolve (MTTR) for Escalated Tickets
The average time it takes you to resolve network incidents that have been escalated to you from junior engineers or the service desk.
Target · Maintain an MTTR of under 2 hours for all Tier 2/3 network incidents.

A critical application went down. It was escalated to you. You diagnosed a BGP peering issue and restored service in 45 minutes. That's well within target.

Technical Leadership & Mentorship
Your ability to guide junior engineers, share your knowledge, and act as a reliable technical expert for the team.
  • Junior engineers consistently seek your advice before escalating. You regularly conduct code reviews for automation scripts. You're seen as the 'go-to' person for complex troubleshooting. You've helped at least one junior engineer take on significantly more responsibility or achieve a promotion within 18 months.
Documentation Quality & Standards
How well you maintain and improve our network diagrams, runbooks, and configuration standards.
  • Our network diagrams are always up-to-date and accurate after your changes. New engineers can easily follow your documentation to troubleshoot issues. You've proactively identified gaps in our existing documentation and filled them in, or even established new, clearer standards for the team.
Proactive Problem Solving
Your knack for spotting potential issues before they become full-blown outages, and your ability to propose and implement solutions.
  • You've identified a looming capacity issue on a core link and proposed an upgrade before it impacted users. You've spotted unusual traffic patterns on monitoring dashboards and investigated, preventing a security incident. You're not just waiting for alerts
  • you're actively looking for trouble.
Cross-Team Collaboration
How effectively you work with other teams (like security, servers, applications) to resolve issues and deliver projects, without engaging in blame games.
  • Other teams consistently praise your helpfulness and willingness to collaborate. You're often the one bridging communication gaps between different technical silos during an incident. You actively participate in cross-functional project meetings and contribute valuable network insights.

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 diagnosing an intermittent network issue that's been baffling the team for days. You enjoy the challenge of figuring out how different network components interact and identifying the subtle misconfiguration causing a problem.

Spending an afternoon deep-diving into Wireshark captures to finally pinpoint why a specific application's traffic is experiencing latency, and then implementing a QoS policy to fix it.

Building and Improving Things

You're not just interested in fixing what's broken; you want to make the network better, faster, and more resilient. You enjoy designing new solutions, implementing them, and seeing the positive impact on the business.

Leading the deployment of a new SD-WAN solution to improve branch office connectivity and reduce MPLS costs, then optimising its performance post-launch.

Mentoring and Sharing Knowledge

You genuinely enjoy helping junior engineers understand complex concepts, reviewing their work, and seeing them grow. You're happy to explain 'the why' behind a configuration, not just 'the how'.

Spending time with a new starter, walking them through a complex BGP configuration, explaining route selection, and answering their questions patiently.

What frustrates people
  • The 'It's Always the Network' Blame Game: Being the default scapegoat for every slow application, forcing you to spend hours proving network innocence with packet captures.
  • Vendor Finger-Pointing: Being stuck in the middle of a multi-vendor outage where the ISP, hardware vendor, and software provider all blame each other while you're trying to fix the problem.
  • Chasing Ghosts: Spending days troubleshooting an intermittent issue that mysteriously disappears the moment you start actively monitoring it.
  • Outdated Documentation: Relying on a network diagram from three years ago to troubleshoot a critical outage, only to find it's dangerously inaccurate.
  • 2 AM Change Windows: The reality that most significant network changes must be performed in the dead of night or on a weekend to minimise business impact, wrecking your sleep schedule.
  • Legacy Gear: Being forced to support ancient, out-of-warranty hardware that lacks modern features and is a ticking time bomb for failure.
What this role does not give you
  • A 9-to-5, strictly predictable schedule – urgent issues don't care about your plans.
  • A role where you're always building new, shiny things; a lot of the work is about maintaining and optimising existing infrastructure.
  • An environment where every decision is made by you; you'll need to collaborate and get buy-in from others.

8Who you work with

This role directly impacts the reliability and performance of our entire IT infrastructure. When the network's healthy, the business runs smoothly. You're essentially the guardian of our digital arteries, making sure information flows freely and securely. Get it right, and you prevent costly downtime and security breaches. Get it wrong, and the business stops, plain and simple.

Inside the business
  • Lead Telecoms Engineer (your manager)
  • IT Security Team
  • Server & Applications Teams
  • Project Managers (for larger initiatives)
  • Service Desk (for escalation points)
  • Architecture Team
Outside the business
  • Network hardware and software vendors (e.g., Cisco, Juniper, Palo Alto)
  • Internet Service Providers (ISPs)
  • External auditors (occasionally for compliance checks)
  • Senior clients (if their network directly integrates with ours)

9What 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 as a Telecoms or Network Engineer, dealing with complex enterprise networks.
  • Proven ability to independently troubleshoot and resolve Tier 2/3 network incidents.
  • Demonstrable experience with configuring and managing enterprise-grade routers and switches (e.g., Cisco, Juniper).
  • A solid understanding of firewall concepts and experience with at least one major firewall vendor (e.g., Palo Alto, Cisco ASA, Fortinet).
  • Experience with network monitoring tools and using them to proactively identify issues.
  • Some exposure to network automation concepts or scripting (e.g., Python, Ansible).

10What to practise next

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

Advanced Cloud Networking & Hybrid Architectures

More of our applications and data are moving to the cloud, but we'll always have some on-premise infrastructure. You'll need to master how to seamlessly and securely connect these hybrid environments, ensuring consistent performance and policy application.

Cloud Transit Gateways/Hub-and-Spoke · Direct Connect/ExpressRoute Optimisation · Cloud Network Security Groups & Firewalls · Multi-Cloud Connectivity

  • This week: Complete an introductory course on AWS VPC or Azure VNet networking.
  • This month: Map out our current on-premise to cloud connectivity and identify potential bottlenecks or single points of failure.
  • Month 2: Design a hypothetical hybrid cloud network architecture for a new application.
  • Month 3: Experiment with a cloud networking lab environment, deploying virtual routers and firewalls.

Quick win: Familiarise yourself with the basic networking components in our primary cloud provider. Understand what a VPC/VNet is and how it's used.

11Staying current once you are in

  • Regularly attending industry webinars and virtual conferences (e.g., Cisco Live, Juniper NXTWORK, Network Field Day) to stay current with emerging technologies.
  • Participating in online network engineering communities and forums to share knowledge and learn from peers.
  • Maintaining a home lab environment to experiment with new configurations, automation scripts, and network devices.
  • Reading technical blogs, whitepapers, and books on advanced networking topics and security best practices.
  • Taking advantage of internal training programmes and knowledge-sharing sessions within our team.

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.

NetDevOps & Infrastructure as Code (IaC)

Manual network configuration is slow, error-prone, and doesn't scale. Competitors are already using NetDevOps to deploy changes faster, with fewer errors, and to maintain consistent configurations across hundreds of devices. This isn't just a 'nice to have' anymore; it's becoming standard practice.

  • Version Control (Git)
  • CI/CD Pipelines for Network Changes
  • Network State Validation
  • API-driven Network Management

Secure Access Service Edge (SASE) & Zero Trust Networking

The traditional network perimeter is gone. Users are everywhere, applications are in the cloud, and the old 'trust everyone inside the network' model is a massive security risk. SASE and Zero Trust are the future of secure connectivity, and we need engineers who can design and implement these architectures.

  • Identity-Centric Access
  • Cloud-Native Security Services
  • Micro-segmentation
  • Continuous Verification

  1. Lead Telecoms Engineer / Network Architect (L4)

    3-5 years from Senior Engineer

    This is a significant jump. You'll move from leading workstreams to designing major network solutions and setting technical standards for the entire team. You'll also take on direct reports and manage a small team.

    • Designing complex network solutions (e.g., new data centre fabric, SD-WAN rollout, large-scale cloud connectivity).
    • Developing and driving the network automation strategy for the department.
    • Architecting highly available and disaster-recoverable network infrastructures.
    • Providing technical leadership and mentorship to multiple senior and junior engineers.
Working with AI on the job

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 reports. What if you could offload some of that to an intelligent assistant? Our AI Productivity Hub isn't about replacing you; it's about giving you superpowers.

As a Senior Telecoms Engineer, you're already juggling complex troubleshooting with project work and mentoring. Imagine having an AI co-pilot that helps you cut down on research, automate incident summaries, and even predict potential failures. That's what we're building towards, and you'll be at the forefront of using these tools.

Automated Root Cause Analysis

Point an AIOps platform (like LogicMonitor or Dynatrace) at our logs, metrics, and topology data. The AI then correlates events across different systems to pinpoint the likely root cause of an outage in minutes, instead of you manually sifting through hours of log files. This means faster fixes and less stress during critical incidents.

Predictive Failure Analysis

AI models can analyse long-term performance data – think interface errors, memory creep on a router, or unusual fan speeds. It'll then predict when a piece of hardware is likely to fail. This lets us proactively replace kit during a planned maintenance window, completely avoiding an emergency outage and a 'truck roll'.

Security Vulnerability Summarisation

Feed a newly announced CVE (Common Vulnerability and Exposure) report for a network OS into an AI assistant. It can quickly summarise the threat, identify which specific device models are affected in our inventory, and even draft an initial impact assessment and remediation plan. This saves you hours of research and helps us patch faster.

Post-Incident Report Generation

After an outage, you've got to write that dreaded Post-Incident Report (PIR). Now, you can feed the incident timeline, ticket notes, and key metrics into an AI tool. It'll generate a structured, business-friendly PIR draft, including a summary, timeline, business impact, and root cause. You just refine it, saving you 1-2 hours of tedious documentation work per incident.
