1What this role really is

You'll be the go-to person for keeping our critical machinery running smoothly across various international sites. This isn't just about fixing things when they break; it's about figuring out why they break, stopping it from happening again, and making sure our assets perform better, for longer. You'll spend your days digging into data, leading investigations into equipment failures, and designing smarter maintenance plans. It's a hands-on role, but with a strategic edge, where your decisions directly impact our production output and bottom line. Think of yourself as a detective, an engineer, and a bit of a coach all rolled into one.

3What 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 inWhere you are nowThe step above
Technical Methodology for RCAFollows prescribed RCA methodology; escalates any deviations or complex scenarios.Applies standard RCA tools (e.g., 5 Whys, Fishbone) independently; consults on novel failures.Leads complex RCA investigations, selects appropriate advanced tools (e.g., Fault Tree Analysis), and defines the overall investigative approach. Consults with Site Maintenance Manager on significant findings or high-impact corrective actions.
PM Schedule OptimisationExecutes PM tasks as scheduled; reports any issues with existing schedules.Proposes minor adjustments to PM frequencies based on equipment performance data; seeks approval from supervisor.Designs and implements comprehensive PM/PdM optimisation strategies for critical assets, including transitioning from time-based to condition-based maintenance. Has authority to modify PM tasks within agreed parameters, informing the Site Maintenance Manager of significant changes and expected impact.
Vendor Selection (Specialist Services)Identifies potential vendors based on pre-approved lists; provides basic information for procurement.Evaluates proposals from pre-qualified vendors for routine services; recommends preferred option to manager.Identifies, evaluates, and recommends specialist vendors for specific reliability projects (e.g., advanced PdM services, specific repair expertise). Can approve contracts up to £10K; larger contracts require Site Maintenance Manager approval, with your strong recommendation.
Project Budget Allocation (within project scope)Tracks project expenditure against budget; reports variances.Manages project spend for routine tasks within a defined budget; seeks approval for any overruns.Manages project budgets typically up to £50K for assigned reliability improvement projects. Has authority to allocate funds within this budget, but must provide clear justification for expenditure and report regularly to the Site Maintenance Manager on financial status.

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.

Site OEE Improvement
Overall Equipment Effectiveness (OEE) for critical production lines.
Target · Increase OEE by 5-8% on designated 'bad actor' assets within 12 months.

If a key packaging line's OEE is at 68% today, you'd aim to get it to 73-76% by identifying and fixing underlying availability, performance, and quality losses.

Unplanned Downtime Reduction
Reduction in hours of unplanned downtime for critical equipment.
Target · Reduce unplanned downtime by 10-15% year-on-year for identified critical assets.

If a specific pump failed for 20 hours last quarter, your goal would be to bring that down to 17-18 hours, or even eliminate the failure completely through a robust RCA and corrective action.

MTBF (Mean Time Between Failures) Improvement
Increase in the average time between failures for 'bad actor' equipment.
Target · Improve MTBF by 20-25% on selected critical assets within 12-18 months.

If a specific motor typically fails every 300 operating hours, you'd be looking to push that to 360-375 hours through better maintenance strategies or design changes.

PM Programme Optimisation Savings
Identifiable cost savings or efficiency gains from optimising preventive maintenance tasks.
Target · Deliver £50K-£100K in annualised savings or equivalent labour hour reductions through PM optimisation.

By reviewing a PM task that takes 8 hours every month and finding a way to safely extend it to every 3 months, you've saved 64 hours of labour annually for that single task, which we can then quantify in cost.

RCA Quality & Effectiveness
The thoroughness and impact of your Root Cause Analysis investigations.
  • You'll be leading RCAs on major failures. Evidence of success includes: clear, well-documented RCA reports, identification of true root causes (not just symptoms), and the implementation of effective, sustainable corrective actions that prevent recurrence. We'll know it's working when the same issues stop cropping up.
Cross-Functional Collaboration
How well you work with and influence different teams (Production, Engineering, Site Maintenance) across various international sites.
  • You'll be seen as a trusted advisor, not just 'the reliability guy'. People from other departments will actively seek your input on operational issues. You'll run effective workshops, get buy-in for your recommendations, and navigate cultural differences smoothly to get things done. Feedback from Site Managers and Production Leads will be key here.
Mentorship & Knowledge Transfer
Your ability to share your expertise and elevate the skills of junior team members and technicians.
  • You'll be actively coaching junior engineers on RCA techniques or PdM technologies. We'll see evidence in improved problem-solving skills from your mentees, their increased confidence in tackling complex issues, and their ability to independently apply reliability principles. This isn't formal management, but it's about making others better.
Proactive Problem Identification
Your knack for spotting potential reliability issues before they become major breakdowns.
  • You'll be bringing forward data-driven insights about emerging failure patterns or underperforming assets, proposing solutions before a crisis hits. This means you're not just reacting to alarms but actively hunting for the next 'bad actor' using data from our CMMS and PdM tools. We'll see this in your contributions to weekly maintenance planning meetings and your project proposals.

5Would you like it

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

What people enjoy
Solving Complex Puzzles

You love diving deep into a tricky equipment failure, sifting through data, talking to technicians, and piecing together the 'why'. The satisfaction comes from finding the root cause and implementing a fix that actually works.

Spending a week on a persistent vibration issue on a critical motor, finally pinpointing a subtle alignment problem, and seeing the vibration levels drop after your fix.

Making a Tangible Impact

You're driven by seeing real, measurable improvements in how our assets perform. Knowing your work directly contributes to less downtime, lower costs, and smoother operations is what gets you up in the morning.

Implementing a new predictive maintenance strategy that reduces unplanned downtime on a specific asset by 20% in its first six months.

Continuous Improvement

You're always looking for a better way to do things – whether it's optimising a PM schedule, improving a work instruction, or finding a more reliable component. 'Good enough' isn't good enough for you.

Reviewing an existing PM task, finding it's over-engineered, and streamlining it to save technician time without compromising safety or reliability.

What frustrates people
  • The constant battle with Production teams who refuse to release equipment for planned maintenance, leading to bigger, more costly breakdowns later.
  • Trying to perform a global analysis when each region logs work orders, failure codes, and asset data differently, making apples-to-apples comparisons impossible.
  • Discovering a dangerous, undocumented bypass or 'temporary' repair made by a previous shift that has now become a permanent, ticking time bomb.
  • Pushback from local sites when trying to implement a global maintenance standard, undermining efforts to create a unified, best-practice approach.
  • Being held accountable for decades of underinvestment and deferred maintenance, with the expectation to achieve world-class reliability with a shoestring budget.
  • A critical machine is down, and the only available spare part is on the other side of the world, stuck in customs, or has a 52-week lead time.
What this role does not give you
  • A purely theoretical or academic role; you'll be dealing with real-world, messy operational challenges.
  • A quiet, predictable 9-to-5 job; urgent issues can and will pop up, sometimes requiring quick action.
  • A role where you can always see every single piece of your work make it to production or get fully implemented without compromise.
  • A role where you're solely focused on one specific site or one type of equipment; you'll have a broad, international remit.

6Who you work with

This role directly impacts our operational efficiency and profitability by minimising costly unplanned downtime and optimising maintenance expenditure. Your work ensures our production assets are reliable, safe, and perform at their peak, which is absolutely critical for meeting customer demand and maintaining our competitive edge globally.

Inside the business
  • Site Maintenance Managers (across various international locations)
  • Production Leads and Supervisors
  • Local Engineering Teams (Process, Mechanical, Electrical)
  • Global Operations Excellence Team
  • Procurement and Supply Chain (for spare parts and vendor services)
  • Health, Safety, and Environment (HSE) Teams
Outside the business
  • Key Equipment Vendors and OEMs (Original Equipment Manufacturers)
  • Specialist Maintenance Service Providers
  • Technical Consultants (for specific reliability challenges)

7What you need before you start

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

  • Proven experience (5+ years) in a dedicated reliability engineering or senior maintenance engineering role within a manufacturing or heavy industrial environment.
  • Demonstrable track record of leading successful Root Cause Analysis (RCA) investigations and implementing effective corrective actions.
  • Strong analytical skills, including experience working with large datasets from CMMS and condition monitoring systems.
  • Experience with developing and optimising Preventive and Predictive Maintenance programmes.
  • Ability to work effectively in a matrix organisation, influencing teams across different sites and cultures.
  • Excellent written and verbal communication skills in English, with the ability to present complex technical information clearly.

8What to practise next

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a big chunk of your day can get eaten up by digging through data, writing reports, and trying to make sense of disparate information. Imagine if you could offload some of that grunt work to AI, freeing you up to focus on the truly complex problem-solving. Well, you can.

Our Operations teams are already starting to use AI to make maintenance smarter, faster, and more predictive. We're not talking about robots taking over, but intelligent tools that help you get to the root cause quicker, optimise schedules better, and prevent breakdowns before they happen. Honestly, it's a game-changer for reliability engineers.

Predictive Work Order Automation

Imagine AI analysing real-time sensor data from our equipment (vibration, temperature, pressure) and automatically generating a detailed work order in SAP PM days before a predicted failure. It'll even suggest the required parts, link to SOPs, and flag necessary safety permits. This means less manual analysis and more proactive maintenance.

AI-Powered Root Cause Analysis

When a failure inevitably happens, an AI agent can instantly sift through years of CMMS data, maintenance logs, and sensor histories from similar assets globally. It'll then suggest the three most likely root causes, giving you a massive head start on your RCA investigation and cutting down the time it takes to get to a solution.

Global Spares Inventory Optimisation

AI can scan our entire global MRO inventory, look at supplier lead times, and even factor in shipping logistics to recommend optimal stock levels for critical spares at each site. This helps prevent costly stock-outs and significantly reduces excess carrying costs, making sure we have what we need, where we need it.

Multilingual Maintenance Report Summariser

Dealing with daily maintenance reports from sites speaking German, Mandarin, or Spanish can be a pain. An AI tool can ingest all those reports, no matter the language, and provide you with a concise, summarised executive brief in English, highlighting critical issues, actions taken, and any escalations needed. No more manual translation or endless consolidation.

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 Reliability 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 10 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 Reliability Engineer: personal to you, and it still counts. The first steps are free.
