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 Plan First Pass Yield

The percentage of your designed test plans that run to completion without needing significant revisions or re-scoping due to unforeseen issues or missing details.

Target · >95% success rate for major test plans

You design a new product validation plan; it runs through all stages without needing a complete overhaul because you missed a critical environmental condition or a key performance metric. That's a pass.

Validation Cycle Time Reduction

Your contribution to shortening the overall time it takes to validate a new product or feature, without compromising quality or thoroughness.

Target · 10-15% reduction in average validation cycle time per year

By optimising test sequences and introducing parallel testing, you help reduce a 12-week validation programme to 10 weeks, freeing up engineering time and accelerating time-to-market.

Mentee Competency Achievement

How effectively your direct reports (Test Technicians, Validation Assistants) grow in their technical skills and ability to independently execute complex test protocols.

Target · All mentees achieve independent status on 3 core test protocols within 6 months of joining your team

Two new Validation Assistants join your team; after six months, both can confidently set up and run our most challenging thermal cycling and vibration tests without constant supervision, thanks to your guidance.

Defect Detection Rate (Early Stage)

The percentage of critical design defects identified and reported by your team during early-stage validation (before manufacturing prototypes).

Target · >80% of critical design flaws identified before DVT (Design Validation Testing)

Your team's rigorous component-level testing uncovers a material fatigue issue in a critical part during EVT (Engineering Validation Testing), allowing the design team to fix it before expensive tooling is made.

Strategic Input Quality

The value and impact of your contributions to product design reviews, risk assessments, and overall R&D strategy, specifically concerning testability and reliability.

You're regularly invited to early-stage design reviews. Your recommendations on design for testability are frequently adopted. Product teams actively seek your input before finalising specifications. You get asked to present on validation risks to senior leadership.

Test Plan Robustness & Innovation

How well your test plans anticipate potential failure modes and use efficient, creative methods to uncover them, moving beyond standard 'check-box' testing.

Your test plans incorporate advanced techniques like HALT/HASS or complex DOE. You propose novel test methods for new technologies. You're known for finding unexpected failure modes that others missed. Your plans are comprehensive and leave no stone unturned.

Cross-functional Influence

Your ability to get different teams (Design, Product, Quality) to agree on validation priorities, resource allocation, and design changes based on test results.

You successfully negotiate changes to product requirements based on validation findings. You get buy-in from Design Engineers on implementing 'design for testability' principles. You can present uncomfortable test results to a room full of stakeholders and get them to act constructively.

Team Development & Empowerment

How effectively you build a capable, motivated, and independent validation team, fostering their growth and problem-solving abilities.

Your team members feel supported and challenged. They take initiative to solve problems before escalating. You delegate meaningful work and provide constructive feedback. Your team's overall skill level visibly improves year-on-year.

7Would you like it

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

What people enjoy

Solving Complex Technical Puzzles

You get a real kick out of designing a test that uncovers a hidden flaw in a cutting-edge prototype. Figuring out the optimal DOE for a new material or troubleshooting a tricky sensor integration is what gets you out of bed.

Spending a full day deep-diving into a complex thermal-mechanical failure, using your expertise to pinpoint the exact design parameter that needs adjustment, feels incredibly satisfying.

Building and Leading a Capable Team

You enjoy guiding junior engineers, seeing them grow, and empowering them to tackle more challenging validation tasks. You're motivated by creating a high-performing team that delivers consistent, reliable results.

Successfully coaching a Validation Assistant through their first complex Gage R&R study, seeing them confidently present the results to the design team, is a big win for you.

Driving Product Quality and Reliability

You're genuinely passionate about ensuring our products are robust and dependable. Knowing that your strategic test plans prevent failures in the field and contribute to customer satisfaction is a core driver.

Seeing a product you rigorously validated launch successfully with zero field failures related to areas you tested gives you immense professional pride.

What frustrates people

Receiving incomplete or vague design specifications that make it impossible to write a comprehensive test plan.
Dealing with urgent, last-minute requests for 'quick' tests that disrupt carefully planned, long-duration programmes.
Resource constraints – not having enough budget for the ideal test equipment or enough headcount for all the validation work needed.
The constant tension between speed-to-market and thorough, rigorous validation.
Engineers pushing back on test results, insisting 'the rig must be wrong' rather than accepting design flaws.

What this role does not give you

A purely hands-on, individual contributor role; you'll be leading and delegating a lot.
A static environment where test methodologies never change; you'll constantly be evolving our approach.
An escape from internal political navigation; you'll need to influence and persuade across teams.
Complete autonomy over product design; your role is to validate, not to design (though your input is critical).

8Who you work with

You'll directly shape the reliability and quality of our next-generation products. Your work ensures that what we launch is robust and meets all performance claims, protecting our brand and reducing post-launch issues. Frankly, without solid validation, R&D is just guesswork, and you're here to take the guesswork out of it.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, you're already juggling complex test designs, team leadership, and stakeholder demands. What if you could offload some of the heavy lifting and focus more on strategic insights? AI isn't here to replace you; it's here to supercharge your ability to lead and innovate.

For a Lead Testing and Validation Engineer, AI tools can transform how you design tests, analyse mountains of data, and even mentor your team. Imagine having an intelligent assistant that helps you spot anomalies, draft reports, and research obscure standards in minutes, not hours. That's the power we're talking about.

Automated Anomaly Detection

AI models can monitor real-time sensor data from your long-duration tests, automatically flagging subtle deviations that a human eye might miss. This means your team can focus on critical analysis rather than constant vigilance, catching impending failures much earlier and more reliably.

Intelligent Report Generation

Feed raw data files (CSVs, logs) into an AI tool, and it can automatically generate a first draft of your comprehensive test report. This includes standard plots, statistical summaries, and pass/fail tables based on your predefined templates, freeing up significant time for your team to focus on interpretation and recommendations.

Standards & Protocol Research

Need to quickly understand the nuances of a new ISO standard or find specific test parameters within a MIL-STD? Use AI assistants to rapidly search, summarise, and extract relevant information from complex industry standards, saving you hours of manual digging when designing new test plans.

AI-Powered Root Cause Analysis

For visual defects or complex failure modes, AI-powered computer vision systems can analyse images of failed test units (e.g., cracks, wear patterns). These systems can identify and classify defects more consistently and rapidly than human inspection, providing faster, more objective input for your root cause investigations.
