3What this role really is

A senior 5G specialist solves complex network problems, leads optimisation projects and guides less experienced engineers. The work involves designing solutions and making technical decisions. This role acts as the lead troubleshooter for critical parts of a 5G network.

4What you'd actually use

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

Forsk Atoll / Infovista Planet (RF Planning & Simulation) Advanced

Designing and calibrating propagation models, performing complex capacity planning, and running 'what-if' scenarios for new spectrum bands. You'll be the one making sure our network plans are solid.

TEMS Investigation / Accuver XCAL/XCAP / NEMO Analyze (Drive Test & Post-Processing) Advanced

Designing complex test plans, performing deep log analysis (L2/L3 signalling), and correlating UE and network-side logs to find those tricky root causes. You'll be the detective with the data.

NetScout / Viavi Observer / Keysight Hawkeye (Performance Monitoring & Assurance) Advanced

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.

Optimisation Impact (Throughput/Efficiency)
The measurable improvement in average user throughput or spectral efficiency within your assigned optimisation areas.
Target · Deliver a measurable >15% improvement in average user throughput or spectral efficiency in a target optimisation area per quarter.

After your project, the average download speed in the City Centre cluster jumped from 150 Mbps to 180 Mbps, a 20% increase, because you re-tuned the Massive MIMO beams.

Problem Resolution Time (MTTR)
How quickly you get to the bottom of and fix complex, cross-domain network issues.
Target · Reduce Mean Time to Repair (MTTR) for complex, cross-domain issues by 20% compared to the team average.

A tricky VoNR jitter issue that usually takes 3 days to fix was resolved in 2 days thanks to your systematic E2E tracing and collaboration with the Core team.

Network KPI Adherence (Critical Clusters)
Maintaining key performance indicators like accessibility and drop call rate in the critical network clusters you're responsible for.
Target · Maintain >99.8% Accessibility and <0.5% DCR (Drop Call Rate) in assigned critical clusters.

Your assigned business park cluster consistently stays above 99.9% accessibility, even during peak hours, because of your proactive tuning.

Project Delivery Schedule Adherence
How well you stick to the timelines and milestones for the optimisation and troubleshooting projects you lead.
Target · Complete 90% of assigned projects on time and within the agreed scope.

The stadium capacity upgrade project, which you led, went live two days ahead of schedule, just in time for the big match.

Mentorship Effectiveness
The impact you have on the growth and development of junior engineers on the team.
  • At least one mentored engineer is promoted or takes on lead project responsibilities within 18 months. Junior team members consistently seek your advice and feedback. They show measurable improvement in their technical skills and problem-solving approach after working with you.
Technical Leadership & Innovation
Your ability to identify and champion new technical approaches or solutions that benefit the network.
  • You propose and successfully pilot a new optimisation technique that becomes a team standard. Your insights are regularly sought out by peers and managers for complex technical challenges. You present findings or new ideas at internal technical forums.
Proactive Problem Identification
Your knack for spotting potential network issues before they blow up into major incidents.
  • You flag an emerging trend in RACH failures in a specific area and propose a fix before it impacts customer experience. You identify a subtle pattern in performance monitoring data that indicates a looming capacity crunch.
Cross-Functional Collaboration
How well you work with other teams (Core, Transport, Field Ops) to solve E2E problems.
  • Other teams frequently praise your collaborative approach in incident reviews. You successfully mediate between different vendor teams to resolve an outage. You're seen as a bridge-builder between technical domains.

7Would you like it

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

What people enjoy
Solving Tough Technical Puzzles

You get a real kick out of unravelling a complex network issue that's been baffling everyone for days. The harder the problem, the more satisfying the solution.

Spending an entire afternoon correlating UE logs with gNB traces to finally pinpoint the exact signalling message causing a persistent handover failure, and then designing the fix.

Seeing Tangible Network Improvements

You're driven by the direct impact of your work on network performance and customer experience. You love seeing KPIs improve because of your efforts.

Monitoring the dashboards after a major optimisation project you led, and watching the average user throughput in a busy area jump by 25%.

Mentoring and Developing Others

You enjoy sharing your knowledge and helping junior engineers grow. You find satisfaction in guiding them through complex tasks and seeing them 'get it'.

Spending an hour walking a junior engineer through a difficult propagation model calibration, patiently explaining the 'why' behind each step, and seeing them confidently tackle it next time.

What frustrates people
  • The Heisen-bug: Those maddening, intermittent network problems that mysteriously vanish the moment you start detailed logging or dispatch a field technician. It's like the network is playing tricks on you.
  • Vendor Finger-Pointing: Being stuck in the middle of a multi-vendor outage where the RAN vendor blames the core vendor, who then blames the transport provider. Getting everyone to agree on a root cause can be a nightmare.
  • Chasing Ghosts: Spending days hunting for an interference source that, after extensive triangulation and demodulation, turns out to be a faulty air conditioner or a cheap imported baby monitor in a nearby building.
  • The 'Magic Bullet' Request: Pressure from management to find a single, cheap parameter change that will magically fix a complex capacity issue without any significant investment. The reality is usually much messier.
  • Explaining RF Physics to Sales: Trying to patiently justify to the sales team why they can't realistically promise five bars of 5G coverage inside a thick concrete-and-steel hospital basement for a private network deal.
  • Outdated Documentation: Relying on site drawings and configuration files that are three years old and bear little resemblance to what's actually physically deployed on the tower. It's like solving a puzzle with half the pieces missing.
What this role does not give you
  • A completely predictable, routine 9-to-5 schedule. Urgent network issues don't care about your plans.
  • A guarantee that every single one of your brilliant technical solutions will be immediately implemented. Budget and business priorities often get in the way.
  • A quiet, isolated work environment. You'll be collaborating constantly, often on high-pressure calls.

8Who you work with

Your work directly impacts our network's quality of service, customer satisfaction, and overall operational efficiency. Get it right, and we're known for having a top-tier network. Get it wrong, and we're dealing with customer churn and a lot of negative press. You're essentially a guardian of our network's reputation and performance.

Inside the business
  • Lead 5G Engineer (your manager)
  • Core Network Team (for E2E troubleshooting)
  • Transport Network Team (for backhaul issues)
  • Product Development (for new service launches)
  • Field Operations (for site visits and data collection)
  • Network Operations Centre (NOC) (for incident management)
Outside the business
  • Network Equipment Vendors (e.g., Ericsson, Nokia, Huawei)
  • Consultants on specific projects
  • Key enterprise clients (occasionally, for bespoke solutions)

9What you need before you start

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

  • Proven experience (at least 2-3 years) as a 5G Specialist or RF Engineer, demonstrating independent problem-solving and project execution.
  • A track record of successfully leading smaller technical projects or workstreams, showing you can take ownership and drive results.
  • Demonstrable experience with at least two of the core RF planning, drive test, or performance monitoring tools listed above at an independent level.
  • A solid understanding of 3GPP Release 15 and 16 features, with practical experience troubleshooting issues related to them.
  • Strong analytical skills, with a proven ability to interpret complex data sets and draw actionable conclusions.
  • Experience mentoring or informally guiding junior colleagues, even if it wasn't a formal part of your previous role.

10What to practise next

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

Advanced Network Slicing Orchestration

As network slicing becomes more prevalent, we'll need to move beyond just designing slices to actively orchestrating and managing their lifecycle, ensuring QoS guarantees are met dynamically. It's about making slices truly intelligent and self-managing.

Service Level Agreements (SLAs) for Slices · Orchestration Platforms (e.g., ONAP, ETSI NFV MANO) · Closed-Loop Automation for Slices · Security Considerations for Multi-Tenant Slices

  • This quarter: Take an online course on network function virtualisation (NFV) and software-defined networking (SDN) concepts.
  • Next quarter: Research open-source orchestration projects like ONAP and try to understand their architecture.
  • Month 6: Participate in internal discussions or working groups focused on our network slicing strategy.
  • Month 9: Propose a small-scale proof-of-concept for automating a simple slice lifecycle management task.

Quick win: Start familiarising yourself with the 5QI values and their mapping to different service types—this is the foundation of slicing.

Data Engineering for Network Observability

We're drowning in network data, but often struggle to make it easily accessible and usable for advanced analytics. The ability to structure, clean, and pipe this data into analytical platforms will be crucial for building predictive models and automated optimisation solutions.

Data Pipelines (e.g., Kafka, Spark) · Data Schema Design for Network KPIs · Cloud Data Warehousing (e.g., Snowflake, BigQuery) · API Integration for Network Elements

  • This quarter: Pick up a book or online course on fundamental data engineering concepts.
  • Next quarter: Work closely with our data platform team to understand how they ingest and process network data.
  • Month 6: Take ownership of improving the data quality or accessibility for one specific network KPI you frequently use.
  • Month 9: Develop a Python script that pulls data from a new network element's API and pushes it into a structured format.

Quick win: Spend some time understanding the data models used in our existing performance monitoring tools. Where does the data come from? How is it stored?

11Staying current once you are in

What people here do to keep up
  • Regularly engage with 3GPP specifications and industry whitepapers to stay current with 5G evolution.
  • Attend relevant industry conferences (e.g., MWC, 5G World) and technical webinars.
  • Participate in online forums or communities dedicated to 5G and RF engineering to share knowledge and learn from peers.
  • Actively seek out opportunities to mentor junior engineers and share your expertise within the team.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of your time as a Senior 5G Specialist is spent sifting through logs, generating reports, and trying to spot patterns in mountains of data. What if you could get a significant chunk of that time back? Our AI Productivity Hub is designed to do just that, giving you more headspace for the truly challenging, strategic work.

We're not talking about replacing you; we're talking about giving you a serious upgrade. Imagine having an intelligent co-pilot for your daily tasks, automating the tedious bits so you can focus on designing, troubleshooting, and innovating. This isn't science fiction; it's already here, and we're building the tools to put it directly into your hands.

Automated Log Analysis

Use AI to automatically parse terabytes of gNB logs. It'll identify anomalies and correlate events across thousands of cells, pinpointing the root cause of systemic issues in minutes, not days. No more manually sifting through endless text files.

Predictive Network Optimisation

AI analyses historical traffic and RF data to predict congestion hotspots before they even happen. It then recommends proactive parameter changes—like load balancing or beam adjustments—to sort out issues before they impact our customers. It's like having a crystal ball for network performance.

Intelligent Interference Detection

AI/ML algorithms continuously analyse spectral data, automatically classifying and locating sources of interference (PIM, external jammers). This gives our field teams a prioritised 'hit list', so they're not chasing ghosts. It makes interference hunting much smarter.

KPI Anomaly Report Generation

AI monitors thousands of KPIs in real-time. When it spots a significant deviation, it automatically drafts a preliminary incident report, complete with charts, impact analysis, and probable causes. This means you can start solving the problem straight away, instead of spending hours just investigating it.
