3What this role really is

This job involves building working prototypes from early product concepts, often working with people and parts across different countries. You take an engineer's design and turn it into something that can be tested and refined. It is hands-on, practical problem-solving work, building and testing the most demanding R&D projects.

4What you'd actually use

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

SolidWorks / Autodesk Fusion 360 Advanced

Making minor design modifications for manufacturability (e.g., adjusting tolerances, adding fillets), creating detailed assembly instructions, and troubleshooting CAD issues for junior staff.

Arena PLM / Windchill Advanced

Auditing complex BOMs for accuracy and completeness, creating and managing intricate Engineering Change Orders (ECOs), and training new users on system best practices.

Jira / Asana Advanced

Creating and managing detailed project plans for multiple complex prototype builds, developing custom workflows and dashboards for the team, and tracking international component orders.

NI LabVIEW Intermediate

Modifying existing LabVIEW VIs (Virtual Instruments) to accommodate new test parameters, debugging basic hardware/software communication issues, and guiding junior users.

Microsoft Excel (with Power Query) Advanced

Building complex, multi-sheet models for costed BOMs and detailed test data analysis, using Power Query to clean and import data from various international sources for reporting.

Ultimaker Cura / PreForm Advanced

Optimising print settings (infill, supports, layer height) for strength, speed, and surface finish across different materials, and troubleshooting complex 3D print failures for both internal and external services.

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 choice	Coming in	Where you are now	The step above
Component Sourcing (Minor Deviation)	Escalate to supervisor for approval of any alternative component.	Propose 2-3 alternatives to engineer/manager for approval, providing pros/cons.	Identify, vet, and propose a single, fully justified alternative to the engineer, making a strong recommendation for approval. You'll do the legwork.
Prototype Build Method	Follow established assembly instructions and methods.	Choose between 2-3 established methods based on project needs, with manager consultation.	Design and implement novel assembly sequences or test procedures, justifying the approach based on efficiency, quality, and cost. You're optimising the 'how'.
International Shipping Route/Carrier	Use pre-approved carriers and follow standard shipping procedures.	Select from a list of approved carriers based on cost/speed, escalating any customs issues.	Independently select carriers and routes for complex shipments, proactively managing customs documentation and contingency planning for delays. You're the expert here.
Mentee Task Assignment	Not applicable; receives tasks.	Provides informal guidance; tasks assigned by manager.	Assigns specific tasks to junior team members, overseeing their work and providing direct feedback and support. You're responsible for their output.

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.

Prototype Build Cycle Time Reduction

The average time it takes to complete a complex prototype build, from receiving the final design files to delivering a fully assembled and initially tested unit.

Target · Reduce average build time by 15% for EVT/DVT builds.

If a typical DVT build currently takes 15 working days, you'd aim to get that down to 12.75 days by optimising processes, pre-empting issues, and smart sourcing.

Cost Per Prototype Adherence

How well you manage the material and external service costs for your assigned prototype builds against the agreed budget.

Target · Maintain actual costs within +/- 5% of the approved material and external services budget for each complex build.

For a prototype with a £5,000 material budget, you'd aim to complete it for between £4,750 and £5,250. This means smart sourcing and avoiding costly re-orders.

Supplier Performance Score

The average quality and on-time delivery score for the key international suppliers you actively manage for critical components or services.

Target · Maintain an average supplier performance score of 90%+ for your top 5 suppliers.

If a supplier consistently delivers parts late or with quality issues, that impacts the score. You'd work with them to improve or find alternatives.

Complex BOM Accuracy Rate

The percentage of Bill of Materials (BOMs) for complex builds that you manage which are completely accurate and error-free upon final review.

Target · Achieve >99% accuracy on all BOM entries and updates for complex builds.

Catching that the wrong revision of a PCB was specified, or a critical screw was missing from the BOM before the parts are ordered and the build starts.

Engineering Design for Assembly (DFA) Feedback Quality

The value and impact of your practical feedback to R&D engineers, helping them design products that are easier, faster, and more reliable to assemble.

Engineers actively seek your input during design reviews
your suggestions lead to demonstrable reductions in assembly time or fewer build errors
your name is on the 'acknowledgements' slide in their project reviews. They'll tell us you saved them from a headache.

Mentorship Effectiveness & Team Uplift

How well you guide and develop junior Prototype Development Assistants, helping them grow their skills and confidence.

Junior team members consistently improve their build quality and autonomy
they proactively come to you with questions before escalating
their feedback in 1-on-1s highlights your support
you've helped them 'unstick' themselves from a tricky problem. Essentially, are they getting better because of you?

Problem Resolution & Proactive Risk Management

Your ability to foresee potential build or logistics problems and either prevent them or quickly find effective solutions when they arise, especially for international challenges.

You flag potential customs delays weeks in advance and propose alternative shipping routes
you've got a backup supplier lined up when a primary one fails
critical build blockers are resolved quickly without major schedule impact
project leads praise your ability to 'make things happen' when issues crop up.

7Would you like it

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

What people enjoy

Bringing Ideas to Life

You get a real buzz from taking a digital design and turning it into a physical, working prototype. The satisfaction of seeing a complex assembly come together perfectly, or a new feature actually function, is what drives you.

Spending late nights tweaking a 3D print or assembling a tricky PCB, not because you have to, but because you're genuinely excited to see the finished product and how it performs.

Solving Tricky Technical Puzzles

You enjoy the challenge of figuring out why something isn't working or how to overcome a seemingly impossible build constraint. You're happiest when you're deep in a problem, troubleshooting, and ultimately finding a clever solution.

When a critical part is back-ordered for months, you're not just reporting it; you're actively researching alternative suppliers, proposing design tweaks to use a different component, or even suggesting an in-house fabrication method.

Mentoring & Developing Others

You genuinely enjoy sharing your knowledge and experience with junior team members. You get satisfaction from seeing them 'get it', helping them grow their skills, and watching them become more independent and capable.

Taking the time to walk a new joiner through the intricacies of a BOM scrub, explaining the 'why' behind each step, or guiding them through their first complex international shipment paperwork.

What frustrates people

The 'Minor' Engineering Change: An engineer makes a 'tiny tweak' to a CAD model that invalidates the 50 custom parts you just received from an overseas supplier, forcing a complete re-order and a 4-week delay.
Supplier Roulette: Receiving a batch of components that are out-of-spec, counterfeit, or simply dead-on-arrival, derailing a build schedule while you scramble to find a replacement.
The Black Hole of Customs: A meticulously planned schedule being completely destroyed because a shipment is randomly selected for inspection and sits in a warehouse for two weeks with no updates, with no clear way to get it moving.
Tribal Knowledge: Critical build instructions or component information exists only in a senior engineer's head, and they've just left for a 10-day vacation, leaving you scrambling.
The Scramble for Resources: Fighting for time on the one high-resolution 3D printer or CNC machine with three other 'top priority' projects, and everyone thinks theirs is the most important.
Being the Bearer of Bad News: Having to tell the project lead that their beautifully designed prototype failed the drop test spectacularly on the first try, or that the cost has doubled.

What this role does not give you

A predictable 9-to-5 routine with no urgent requests or shifting priorities.
A role where every single prototype you build makes it into a final product.
An environment where processes are always perfectly defined and followed to the letter.
A quiet, solitary workspace – you'll be interacting with lots of people and equipment.

8Who you work with

This role directly impacts the speed, cost, and quality of our R&D prototyping efforts. Your ability to efficiently build and validate complex prototypes means our engineers get critical feedback faster, leading to quicker design iterations and ultimately, a shorter time-to-market for our new products. You're essentially the engine room for our innovation pipeline, ensuring we can physically test what we design.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, some parts of prototype development can be a bit of a grind. But what if you could offload the tedious bits and focus on the really interesting, hands-on problem-solving? That's where AI comes in. We're building an internal AI Hub to help our R&D team work smarter, not harder.

For a Senior International Prototype Development Specialist, AI isn't about replacing your skills; it's about augmenting them. Imagine shaving hours off BOM scrubs, getting instant insights into potential prototype failures, or having a co-pilot for tricky international logistics. Our AI Hub is designed to take the grunt work out of your day, freeing you up for more complex builds, deeper troubleshooting, and mentoring.

BOM & Compliance Automation

Use an AI-powered tool to automatically scan your Bill of Materials, check every part number against real-time supplier inventory, flag obsolescence risks, and verify compliance with international regulations (like RoHS or REACH). It's like having an army of interns doing the most tedious part of your job, but faster and more accurately. You'll just need to validate the output.

Predictive Failure Analysis

Feed sensor data from your stress tests (vibration, thermal, cycle tests) into an AI model. This model can identify subtle patterns that precede catastrophic failure, allowing engineers to pinpoint weak points in the design much faster than manual analysis. You'll get early warnings, helping you guide engineers to more robust designs before costly physical failures occur.

Global Component Sourcing Assistant

When a specified component is unavailable or too expensive, use an AI agent to scan global supplier databases for functionally equivalent alternatives. The AI considers electrical specs, physical dimensions, lead times, and supplier ratings to provide a ranked list of viable replacements. Think of it as your personal, super-fast sourcing agent, cutting down hours of manual searching to minutes.

Logistics & Communication Co-Pilot

Use a generative AI assistant to draft complex customs declarations, commercial invoices, and status update emails for international shipments. It can pre-fill forms, suggest Harmonised System (HS) codes, and even translate updates for global teams, ensuring clarity and reducing errors. This means less time on paperwork and more time ensuring your prototypes move smoothly across borders.
