3What this role really is

An RF engineer keeps a mobile network running and makes sure customers get a good signal. The work covers checking 4G and 5G cells, tuning their performance, and fixing faults as they arise.

4What you'd actually use

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

Atoll (Forsk) or Planet (Infovista) Intermediate

Running existing propagation models, generating standard coverage plots, performing basic neighbour list analysis, and creating simple new site designs.

TEMS Investigation, NEMO Outdoor/Analyse, or Accuver XCAL Intermediate

Executing pre-defined drive routes, collecting logs, and generating standard KPI reports (e.g., RSRP, SINR plots) to validate performance or troubleshoot.

Python (Pandas, Matplotlib) Intermediate

Running and modifying existing scripts to parse performance counters from the OSS, performing data cleaning and basic analysis, and generating visualisations for reports.

SQL Intermediate

Writing basic to intermediate SQL queries to extract network performance data from our databases for analysis.

Ericsson ENM, Nokia NetAct, or Samsung Service Manager (OSS) Intermediate

Navigating the GUI to check alarms, pull performance counters for specific cells, verify parameter settings, and perform basic configuration changes.

QGIS or ArcGIS Pro Intermediate

Importing network data (cell sites, drive routes) to create thematic maps, measuring distances, and viewing terrain profiles to aid in planning and troubleshooting.

Wireshark Basic

Capturing and applying basic filters to trace call flows and identify common signaling issues at the packet level during troubleshooting.

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
RAN Parameter Changes (e.g., handover thresholds, power levels) Requires explicit approval for every change, often paired with a senior engineer. Can independently make changes within a defined set of 'golden parameters' for assigned clusters, following established procedures. Deviations or changes outside these parameters require manager approval. Can independently make all technical parameter changes within their workstream. Only consults on changes with significant network-wide impact or high risk.
New Site Design / Feature Rollout Assists with data collection and basic design tasks; all designs must be reviewed and approved. Designs simple new sites (e.g., adding a 5G carrier to an existing site) or implements new features on existing cells. These designs are typically peer-reviewed, but you own the technical execution. Leads the design of complex new sites, multi-technology upgrades, or market-wide feature rollouts. Makes technical decisions on architecture and implementation, consulting with Lead/Manager on strategic implications.
Troubleshooting & Root Cause Analysis Follows defined troubleshooting guides; escalates if root cause isn't immediately obvious. Independently investigates and identifies root causes for common and some complex network issues. Proposes and implements fixes, escalating only truly novel or widespread problems. Leads complex, cross-functional troubleshooting efforts for critical network issues. Defines the diagnostic approach and makes decisions on corrective actions, often guiding junior engineers.
Budget Allocation (e.g., for tools, small projects) No budget authority. Requests resources through supervisor. Can recommend small purchases (e.g., software licences, training courses) up to £1,000, which require manager approval. No direct spending authority. Can approve minor project expenses up to £5K without direct manager approval, as long as it's within an approved workstream budget. Consults on larger budget items.

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.

Dropped Call Rate (DCR)
The percentage of calls that disconnect unexpectedly in your assigned clusters.
Target · Below 0.5% consistently

If your cluster has 10,000 calls in a day, we'd expect fewer than 50 to drop. You'll see this on your daily dashboard.

Trouble Ticket Resolution SLA
How quickly you resolve network issues reported by internal teams or customers.
Target · 90% of high-priority tickets resolved within 48 hours

A ticket for a 'no service' area comes in on Monday morning; it needs to be closed by Wednesday morning, ideally much sooner.

KPI Report Accuracy & Timeliness
The reliability and promptness of the routine performance reports you generate.
Target · 99% accuracy; all reports delivered within 24 hours of request

If you're asked for a weekly coverage report, it needs to be spot-on and in their inbox by Tuesday morning, every week.

Data Throughput (DL/UL)
The average download and upload speeds experienced by users in your clusters.
Target · Maintain average DL speeds above 50Mbps (4G) / 200Mbps (5G) and UL speeds above 10Mbps (4G) / 30Mbps (5G)

You'll see a dip in average download speeds in a specific area after a software upgrade; your job is to investigate and fix it.

Problem-Solving Effectiveness
How thoroughly and logically you approach and resolve complex or intermittent network issues.
  • Your manager will look at your troubleshooting documentation, the root cause analysis you provide, and the long-term effectiveness of your fixes. Are you just putting a plaster on it, or actually solving the underlying problem? Do you ask smart questions when you're stuck?
Documentation Quality
The clarity, accuracy, and completeness of your technical documentation for changes, analyses, and troubleshooting.
  • Can another engineer pick up your documentation and understand exactly what you did, why you did it, and what the results were? Is it up-to-date? Frankly, good documentation saves everyone a lot of headaches down the line.
Proactive Issue Identification
Your ability to spot potential problems in your clusters before they become major customer-impacting issues.
  • Are you regularly reviewing performance trends and alarms? Do you flag potential capacity bottlenecks or emerging interference issues before they hit our KPIs? We want you to be a step ahead, not just reacting to fires.
Collaboration with Field Operations
How effectively you work with the Field Operations team to implement changes and resolve on-site issues.
  • Do you provide clear instructions for site visits? Do you follow up promptly? Are you seen as someone who makes their job easier, not harder? Getting things done often means working well with the folks who get their hands dirty.

7Would you like it

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

What people enjoy
Solving Complex Puzzles

You get a real kick out of taking a seemingly impossible network issue, digging into the data, and figuring out the root cause. The 'aha!' moment when you finally crack it is what gets you up in the morning.

Spending a morning correlating drive test logs with performance counters to pinpoint why a specific street has poor 5G coverage, then finding a subtle parameter misconfiguration.

Seeing Tangible Impact

You love seeing your work make a direct difference. When you implement a change and then see the network KPIs improve, or hear positive customer feedback, that's incredibly rewarding for you.

Optimising a cell site in a busy town centre and then seeing the average data speeds for that area jump by 20% in the next daily report.

Continuous Learning & Mastery

You're always keen to learn about the latest 3GPP releases, new vendor features, or a different scripting technique. The idea of becoming a true expert in a specific area of RAN optimisation really appeals to you.

Voluntarily digging into the 5G NR specifications to understand a new feature, or experimenting with a Python library to automate a data extraction task.

What frustrates people
  • The Ghost in the Machine: You'll spend days trying to replicate an intermittent issue reported by a high-value customer, only for it to work perfectly every time you are actively monitoring it. It's infuriating.
  • Vendor Finger-Pointing: Getting stuck in the middle of two vendors (e.g., RAN and Core) who each blame the other's equipment for a network-wide problem. You're the referee, and it's exhausting.
  • Inaccurate Site Documentation: Arriving at a site (virtually or physically) to implement a change only to find the physical hardware (antennas, radios) doesn't match the engineering database, forcing a complete redesign on the spot. It messes up your whole day.
  • The 'VIP Complaint' Fire Drill: Having to drop all planned, strategic optimisation work to urgently investigate a single complaint from an executive who has poor service at their lake house. Priorities often get thrown out the window.
  • Swivel Chair Integration: Manually pulling data from 5 different systems (performance stats, alarm logs, trouble tickets, GIS, inventory) that don't talk to each other just to investigate one problem. It's tedious and a massive time sink.
  • Change Freeze Purgatory: Having a critical network fix ready to deploy but being blocked for weeks by a company-wide 'change freeze' imposed by a different department. You know the fix, but you can't implement it.
  • Explaining SINR to Sales: Trying to explain to the sales team that you can't just 'turn up the power' to fix an interference (SINR) problem, and that the solution might actually involve reducing power. It's like speaking a different language.
What this role does not give you
  • A perfectly predictable 9-to-5 routine – urgent issues do crop up.
  • Complete autonomy over strategic network decisions – you'll be executing, not setting the overall direction.
  • A role where you rarely interact with other teams – collaboration is key here.
  • A job where you never have to deal with legacy systems or imperfect data.

8Who you work with

Your work directly impacts customer satisfaction and retention. When the network performs well in your clusters, customers stay with us, and we avoid costly complaints. You're essentially the guardian of our network's quality in your assigned areas, ensuring our investment in 4G and 5G actually translates into a great user experience. Get it wrong, and we're losing customers and money; get it right, and we're building a reputation for reliability.

Inside the business
  • Senior RF Engineers (your direct manager and peers)
  • Field Operations Team (the folks who go to sites)
  • Core Network Team (they handle the brains of the network)
  • Customer Service (they get the complaints, you help fix them)
  • Network Planning Team (they design the big picture, you make it real)
Outside the business
  • Equipment Vendors (Ericsson, Nokia, Samsung – you'll work with their support teams)
  • Local Authorities (occasionally for site access or specific issues)

9What you need before you start

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

  • A solid foundation in radio frequency (RF) theory and wireless communications principles. You should know your decibels from your dBms.
  • Demonstrable experience working with mobile network performance data (4G/5G).
  • Experience with at least one major RF planning or optimisation tool (e.g., Atoll, Planet, TEMS, NEMO).
  • Basic scripting skills in Python or strong SQL for data extraction and manipulation.
  • A track record of methodical troubleshooting and problem-solving in a technical environment.
  • The ability to work independently on assigned tasks and manage your own workload effectively.

10What to practise next

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

Advanced RAN Parameter Optimisation

As networks become more complex with 5G features like Massive MIMO and network slicing, the interplay of parameters becomes incredibly intricate. You'll need to move beyond basic tuning to understanding the dependencies and second-order effects of changes.

Inter-feature Optimisation · Self-Organising Networks (SON) principles

  • This quarter: Dive deeper into vendor-specific parameter guides for 5G NR. Understand the 'why' behind each setting.
  • Next 6 months: Take on a project focused on optimising a specific, complex 5G feature (e.g., dynamic spectrum sharing) end-to-end.

Quick win: Challenge yourself to explain the impact of a single parameter change on three other KPIs or network behaviours.

Advanced Protocol Analysis (5G NR)

With the introduction of new 5G protocols and interfaces, the ability to deep-dive into signaling traces will become even more critical for complex troubleshooting and understanding network behaviour at a granular level.

5G NR RRC and NAS Procedures · Core Network Interfaces (e.g., N2, N3)

  • This quarter: Spend time analysing 5G NR traces using Wireshark or vendor-specific tools. Focus on understanding call flows.
  • Next 6 months: Look for advanced training on 5G protocol analysis, perhaps from a vendor or a specialist training provider.

Quick win: Practice decoding a full 5G NR call setup and handover sequence from a captured trace.

11Staying current once you are in

What people here do to keep up
  • Regularly engage with 3GPP specifications and industry whitepapers to stay current on 5G NR evolution and future standards.
  • Participate in relevant industry forums, webinars, and online communities to share knowledge and learn from peers.
  • Attend vendor training sessions on new features or optimisation techniques as they become available.
  • Actively seek out opportunities to mentor junior team members or share your knowledge through internal presentations.

12The rising capability

The rising capability

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.

O-RAN & Cloud-RAN Architectures

The industry is moving towards more open, virtualised, and disaggregated Radio Access Network (RAN) architectures. This means multi-vendor integration, software-defined networks, and a shift from hardware-centric to software-centric thinking. It's not just a buzzword; it's the future of RAN.

  • RIC (RAN Intelligent Controller)
  • CU/DU Split
  • Virtualisation & Containerisation
  • Multi-Vendor Integration Challenges

AI/ML for RAN Optimisation (Practical Application)

While we have AI tools now, the ability to actually build and train simple AI/ML models for specific RAN use cases (like predictive anomaly detection or automated parameter tuning) will become a differentiator. It's moving beyond just using the tools to understanding how they work and making them better.

  • Supervised vs. Unsupervised Learning
  • Feature Engineering for RAN Data
  • Model Evaluation Metrics
  • Basic Python ML Libraries (scikit-learn, TensorFlow/PyTorch basics)

    • Contributing to the development of network-wide optimisation strategies.
Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, a big chunk of an RF Engineer's day involves sifting through mountains of data, trying to spot the needle in the haystack. But what if you could offload the grunt work to AI and focus on the really interesting, high-impact problems? That's exactly what we're building towards.

Our AI Productivity Hub is designed specifically for Technical_roles, especially those in Telecommunications and 5G. It's not about replacing your expertise; it's about giving you superpowers. Think of it as having a tireless, super-smart assistant that handles the repetitive, data-heavy tasks, freeing you up to do more strategic thinking and complex problem-solving. We're talking about real, tangible time savings, letting you focus on what truly matters: keeping our network best-in-class.

Automated Log Analysis

Imagine feeding terabytes of raw network logs and performance counters into an AI model. It instantly parses the data, flags anomalies, identifies patterns, and correlates events that would take you days to find manually. No more staring at endless lines of text; the AI tells you where to look.

Predictive Network Optimisation

Use machine learning to predict future network congestion or potential cell failures before they happen. Based on historical trends, time of day, and even special events, the system can recommend proactive parameter changes or capacity augments. You fix problems before customers even notice them.

3GPP Spec De-Coder

Ever get lost in the dense, technical language of 3GPP specifications? Our specialised LLM, trained on these documents, lets you ask plain-English questions like 'Explain the main differences in the handover process between NSA and SA 5G' and get concise, accurate summaries with direct references. It's like having an expert on call, 24/7.

Justification & Report Generation

Instead of spending hours drafting reports, provide an AI assistant with the raw data (KPIs before/after, project goals) and have it generate a well-structured technical justification for a network change or a post-mortem report for an outage. It'll be ready for your review and polish, saving you significant writing time.
