3What this role really is

A Testing Technician checks new products and prototypes to make sure they work properly before they reach customers.

4What you'd actually use

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

NI LabVIEW (pre-written VIs) Basic

Executing existing Virtual Instruments (VIs) to control test sequences and acquire data from sensors and DUTs. You'll be pressing 'run' and monitoring outputs, not coding.

NI cDAQ/PXI Hardware Basic

Connecting sensors, power supplies, and Devices Under Test (DUTs) to the data acquisition hardware following detailed diagrams. You'll know your way around the physical connections.

Minitab Intermediate

Entering test data into pre-made templates, running basic statistical analyses (like descriptive stats or capability analysis), and generating standard plots for reports.

Microsoft Excel Intermediate

Organising raw data, performing simple calculations (averages, percentages), creating basic charts, and using it for general data logging and tracking.

Jira Intermediate

Executing test cases, logging defects with clear steps-to-reproduce, updating test status, and tracking your assigned tasks within project workflows.

Confluence Intermediate

Following and updating existing test procedures, accessing technical documentation, and contributing to team knowledge bases with your observations.

Standard Lab Instrumentation (Oscilloscopes, DMMs, Power Supplies, Environmental Chambers) Basic

Manually operating these instruments from their front panels to set parameters, take measurements, and monitor test conditions. You'll know how to turn them on and get a reading.

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
Test Procedure Deviation Must escalate all deviations to supervisor for approval before proceeding. Can propose minor deviations (e.g., using an alternative but equivalent cable) to supervisor for approval. Must escalate major deviations immediately. Can approve minor deviations within established parameters. Must consult Lead Engineer for major deviations or significant changes to test methodology.
Equipment Troubleshooting Perform basic checks (power, connections) then escalate to supervisor. Independently diagnose and resolve common equipment faults (e.g., software glitches, simple wiring issues). Escalate complex or persistent issues. Lead diagnosis of complex equipment failures. Authorise minor repairs or engage external vendors for support up to £1K.
Data Interpretation & Reporting Collect raw data and present it using provided templates. Supervisor interprets results. Perform basic analysis, highlight pass/fail, and summarise key observations. Propose initial conclusions for review. Interpret complex data sets, identify trends, and make recommendations to design engineers. Present findings directly to project teams.
Test Schedule Adjustments No authority. Must report any potential delays to supervisor immediately. Can suggest minor adjustments to personal daily schedule (e.g., shifting a non-critical test by an hour) but must inform supervisor. Cannot impact project deadlines. Can adjust test schedules for individual workstreams within a project, provided overall project milestones are not impacted. Must communicate changes to relevant engineers.

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.

Test Data Accuracy
The percentage of test data sets that are free from recording errors, missing values, or incorrect entries.
Target · ≥99% accuracy

You submit 10 test reports in a week; 9.9 of them (or all 10, if we're being precise) have no data entry mistakes or omissions. If a senior technician flags a missing temperature reading from a critical soak test, that counts against you.

Test Procedure Adherence
The number of deviations from established, documented test procedures.
Target · 0 major deviations per quarter; <2 minor deviations per month

You're running a 10-step vibration test. If you skip a step or use the wrong fixture, that's a deviation. We expect you to follow the script unless you've got a good reason and have flagged it first.

Test Setup & Teardown Efficiency
The average time taken to set up a new test or tear down an old one, compared to estimated times.
Target · Within 10% of estimated setup/teardown times

If a complex environmental test setup is estimated to take 4 hours, you should be getting it done in around 3.5 to 4.5 hours. Consistently taking 6 hours means we need to figure out why.

First-Pass Yield (FPY) of Test Rigs
The percentage of test setups that work correctly the first time, without needing significant troubleshooting or rework.
Target · ≥90% FPY

Out of 10 new test setups you build, 9 of them should power up and run their initial diagnostic checks without you having to spend an hour fixing a loose wire or a software glitch. It's about getting it right first time.

Proactive Troubleshooting
Identifying and attempting to diagnose issues with test equipment or DUTs before escalating them, showing an understanding of the test setup.
  • You'll be the one who tries a few common fixes (e.g., checking cables, restarting software, verifying power) before calling over a senior engineer. Your test logs will show your initial diagnostic steps. When you do escalate, you'll have a clear description of the problem and what you've already tried. Engineers will often say, 'They usually have a good idea of what's going on.'
Documentation Quality
Producing clear, concise, and complete test logs, observations, and reports that are easy for engineers to understand and act upon.
  • Your test reports won't need follow-up questions from engineers to understand the results. Photos will be clear and relevant. You'll use the right templates and fill them out thoroughly. Other technicians might even ask to see your reports as an example of how it should be done.
Lab Organisation & Safety
Maintaining a tidy, organised, and safe workspace, ensuring equipment is properly stored and calibrated, and safety protocols are followed.
  • Your workbench won't look like a bomb site. Tools will be put back in their place. You'll know where the fire extinguisher is and how to use it. There won't be any trailing cables or unmarked hazards. When we do a safety audit, your area will consistently pass with flying colours. Other team members will comment on how organised your area is.
Collaboration & Communication
Effectively communicating test progress, issues, and findings with the team and engineers, asking clarifying questions when needed.
  • You won't just dump data on an engineer's desk
  • you'll give them a quick summary of what you found. You'll ask smart questions about vague test requests. You'll let the team know if a test is running late or if you've hit a snag. People will say you're easy to work with and that you keep them in the loop without needing to be chased.

7Would you like it

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

What people enjoy
Solving Technical Puzzles

You'll get a real kick out of figuring out why a test rig isn't working as expected, or why a prototype is failing in an unusual way. It's about the satisfaction of diagnosing a problem and getting things back on track. Every day brings a new technical challenge to unpick.

Spending an hour tracing a wiring diagram to find a loose connection that was causing intermittent sensor readings, and then seeing the test run perfectly.

Hands-On Product Development

If you love getting your hands on actual hardware, building things, and seeing how products are made and tested, you'll thrive here. You're directly contributing to the physical creation and validation of new technology, not just sitting behind a desk.

Assembling a new test fixture from scratch, connecting all the sensors and power, and then seeing it successfully run its first test on a prototype.

Contributing to Product Quality

You'll feel a genuine sense of responsibility and pride in knowing that your thoroughness helps prevent faulty products from reaching customers. It's about being a guardian of quality and reliability.

Discovering a critical design flaw during an environmental test that, if missed, would have led to widespread product failures in the field.

What frustrates people
  • The 'Prototype from Hell': Getting a fragile, hand-soldered engineering prototype held together with tape and hope, and being expected to run a full suite of rigorous environmental tests on it.
  • Vague Test Requests: Getting a ticket from an engineer that just says, 'See if the battery life is better.' No defined load conditions, no pass/fail criteria, no comparison unit – you'll have to chase for clarity.
  • The Intermittent Gremlin: Spending three days trying to replicate a critical bug that a remote user reported, but it never happens in the lab, making you question your sanity.
  • Documentation Purgatory: Spending hours meticulously documenting a test setup and procedure, only to have the project pivot and render it all obsolete before you even run the first test.
  • Equipment Squeeze: When your project's success depends on the one-of-a-kind thermal chamber, which is booked solid for the next six weeks by a higher-priority project. You'll learn patience.
What this role does not give you
  • High-level strategic decision-making – that's for the engineers and managers.
  • A constant stream of brand-new, never-before-seen tasks every single day.
  • A quiet, sterile office environment – it's a lab, so expect some noise and dust.
  • Direct customer interaction or sales involvement.

8Who you work with

Your work directly influences the reliability and quality of our new products. Catching a design flaw now, in the lab, costs us hundreds of pounds. Missing it and letting it get to production could cost us hundreds of thousands in recalls or warranty claims. You're basically protecting our reputation and our bottom line by being thorough and sharp-eyed.

Inside the business
  • Design Engineers (Mechanical & Electrical)
  • Product Managers (for specific product lines)
  • Quality Assurance Team
  • Manufacturing Engineers (for testability feedback)
Outside the business
  • Equipment vendors (for troubleshooting)
  • Calibration services

9What you need before you start

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

  • At least 2 years of hands-on experience in a testing, R&D, or manufacturing quality control environment.
  • Proven ability to follow detailed technical instructions and procedures accurately.
  • Demonstrable experience with basic lab instrumentation (e.g., DMMs, power supplies, oscilloscopes).
  • Experience using data entry and basic analysis software like Excel or Minitab.
  • A solid understanding of basic electrical and/or mechanical principles.
  • A strong commitment to safety and good lab practices.

10What to practise next

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

Advanced Instrumentation & Sensor Knowledge

We're always bringing in new, more sophisticated sensors and test equipment. You'll need to understand not just how to operate them, but their limitations, calibration requirements, and how to interpret their outputs accurately. This is crucial for reliable data.

Different types of sensors (e.g., strain gauges, a · Signal conditioning and amplification basics · Noise reduction techniques in measurement systems · Understanding instrument specifications (e.g., acc · Advanced calibration procedures and error sources

  • This month: Pick one new type of sensor or instrument in the lab and research its operating principles and typical applications.
  • Month 2: Shadow a Senior Technician or Engineer during a complex instrument setup or calibration.
  • Month 3: Take ownership of the routine calibration for a specific piece of equipment, understanding the full process.
  • Month 4: Propose a better way to connect a sensor or reduce noise in a current test setup, based on your new knowledge.

Quick win: Read the manual for one of the more complex instruments you use regularly. You'll be surprised what you learn about its capabilities and limitations.

Basic Design of Experiments (DoE) Principles

As you progress, you'll be asked to help with more efficient testing. Understanding DoE means you can contribute to designing tests that get more information with fewer runs, moving beyond 'one-factor-at-a-time' testing. This saves time and resources.

Factors, levels, and responses in an experiment · Full factorial vs. fractional factorial designs · Identifying main effects and interactions · Randomisation and replication · Understanding the benefits of DoE over traditional

  • This month: Read an introductory book or online course on Design of Experiments (e.g., 'DOE for Dummies').
  • Month 2: Discuss with a Senior Engineer how DoE is currently used in our R&D projects.
  • Month 3: Help collect data for a DoE study, ensuring you understand which factors are being varied and why.
  • Month 4: Propose a simple DoE setup for a small, non-critical test to experiment with the principles.

Quick win: When an engineer asks you to test something, ask them 'What factors are we changing, and what are we measuring?' It starts the DoE mindset.

11Staying current once you are in

What people here do to keep up
  • Attending industry workshops or webinars on new testing methodologies or equipment.
  • Participating in internal training sessions on new product technologies or test procedures.
  • Seeking mentorship from Senior Testing Technicians or Engineers to deepen your technical understanding.
  • Taking online courses in Python scripting, data visualisation, or basic statistics.
  • Engaging with relevant professional communities or forums to stay updated on best practices.

  • Conditional statements (if/else) and loops (for/wh
  • Basic functions for code reusability
  • Libraries like `pyvisa` for instrument control
  • Reading and writing data to files (CSV, JSON)

Data Visualisation Best Practices

It's not enough to just collect data; you need to present it clearly so engineers can quickly grasp the insights. Bad charts can mislead. Understanding how to create effective visualisations will make your reports far more impactful and save engineers time.

  • Choosing the right chart type for your data (scatt
  • Effective use of colour and labels for clarity
  • Avoiding misleading visualisations (e.g., truncate
  • Creating interactive plots (even basic ones) for d

Working with AI on the job

Working with AI

Where AI is starting to help

Imagine spending less time on the tedious bits of testing and more time on the interesting challenges. That's what AI can do for you. We're not talking about robots taking over your job; we're talking about smart tools that make your life easier, faster, and more accurate. Think of AI as your personal lab assistant, handling the grunt work so you can focus on what truly matters.

In Research & Development, especially in testing, there's a huge opportunity to use AI to speed up data analysis, automate routine checks, and even help you draft reports. It's about working smarter, not harder. Our internal AI Productivity Hub is packed with resources and tools specifically for our R&D team, and here's a sneak peek at how you'll be using it day-to-day as a Testing Technician.

Automated Test Log Analysis

AI can sift through huge amounts of raw sensor data from those long, boring soak tests. It'll automatically flag subtle anomalies, trends, or correlations that a human might easily miss – like a tiny current leak that only appears after 48 hours at high temperatures. It's like having an extra pair of eyes that never gets tired.

Visual Inspection Co-pilot

Picture an AI-powered camera system doing the initial visual check on your DUTs. It can quickly flag potential cosmetic defects, incorrect component placements, or even dodgy solder joints before you even start the functional testing. This means you spend less time manually inspecting and more time on actual testing.

Smart Standards Assistant

Ever spent ages digging through complex industry standards (like ISO or ASTM) to find one specific test parameter? An AI assistant can instantly search and cross-reference these documents to give you the exact information you need for a new material or component. No more manual page-flipping, just quick answers.

Draft Report Generation

After a test, AI can ingest all your structured data – pass/fail results, measurements, log files – and generate a first draft of your test report. It'll include charts, summary tables, and even some initial observations. You then just review, edit, and add your expert insights, saving you hours of tedious writing.
