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
Prototype Build Method Selection Follows supervisor's instructions on chosen method (e.g., 'print this on the FDM printer'). Selects appropriate method for routine parts based on established guidelines (e.g., 'this part needs SLA for detail'). Consults supervisor for novel parts. Independently selects optimal build method for complex, multi-part assemblies, considering trade-offs in cost, speed, and material properties. Proposes new methods if current ones are insufficient. Justifies choices to engineers.
Design for Manufacturability (DFM) Feedback Identifies obvious errors (e.g., 'this hole is too small for our drill bit'). Reports issues to supervisor. Identifies common DFM issues (e.g., unsupported overhangs, tight tolerances) and proposes standard solutions. Consults engineer on implementation. Proactively reviews complex CAD models for subtle DFM challenges, suggesting innovative solutions that optimise for cost, speed, and reliability. Leads discussions with engineers to integrate feedback, often proposing design alternatives.
Troubleshooting & Problem Resolution Reports equipment malfunctions or failed prints to supervisor. Follows basic troubleshooting steps if provided. Diagnoses and resolves routine equipment issues (e.g., clogged nozzle, bed levelling) or common print failures independently, using established procedures. Escalates complex issues. Leads complex root cause analysis for novel equipment failures, persistent print issues, or unexpected prototype behaviour. Develops and implements non-standard solutions. Mentors others on troubleshooting methodology.
Lab Equipment Maintenance & Calibration Performs basic cleaning and preventative maintenance tasks as instructed. Independently performs routine maintenance and calibration according to schedules. Orders standard replacement parts. Takes ownership of specific critical equipment, developing and refining maintenance schedules. Diagnoses and performs minor repairs, often sourcing specialist parts. Trains junior staff on proper equipment care and troubleshooting.

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.

Complex Build Success Rate
Percentage of complex, multi-part or technically challenging prototypes successfully completed on the first attempt, meeting all specified tolerances and functional requirements.
Target · >90%

Successfully built and assembled a new electro-mechanical test fixture with tight tolerances, passing first article inspection (FAI) with zero rework needed, contributing to a 95% success rate for the month.

DFM Feedback Acceptance Rate
Percentage of your Design for Manufacturability (DFM) suggestions that are incorporated into the final CAD model by the engineering team.
Target · >75%

Suggested five specific changes to a new enclosure design to improve printability and assembly; four were adopted by the mechanical engineer, resulting in an 80% acceptance rate for that project.

Lab Equipment Uptime Contribution
Your contribution to maintaining key prototyping equipment (e.g., 3D printers, CNC machines) through proactive maintenance, calibration, and timely troubleshooting, measured by the overall operational availability of the machines you're responsible for.
Target · >95% for assigned machines

Performed weekly preventative maintenance on the Formlabs SLA printer, proactively replacing a worn-out resin tank, ensuring it was available for 98% of scheduled operational hours in Q2.

Mentorship Impact on Junior Task Completion
The improvement in efficiency or quality of tasks completed by junior team members you've mentored, as evidenced by their reduced errors or faster turnaround times on similar tasks.
Target · 20% improvement in junior task efficiency/quality

After a month of your guidance, a junior technician's first-pass success rate on FDM prints increased from 70% to 85%, and their troubleshooting time for common print failures decreased by 25%.

Proactive Problem Solving
Your ability to identify potential issues before they become major problems, and your initiative in finding solutions rather than waiting for instructions.
  • You're often the first to flag a potential material shortage or a design flaw. You'll have already tried a few fixes for a failed print before reporting it. Engineers frequently come to you for practical advice on tricky build challenges.
Quality of Technical Documentation
The clarity, accuracy, and completeness of the build logs, test procedures, and equipment maintenance records you create or update.
  • Your documentation is consistently easy for others to follow, even complex build steps are clearly explained. Junior team members use your documentation as a reference. Audit trails for equipment maintenance are always up-to-date.
Knowledge Sharing & Mentorship
How effectively you share your expertise with the wider team, particularly in guiding and developing junior Prototype Assistants.
  • You regularly offer advice and tips to colleagues. You'll lead informal training sessions on new techniques or equipment. Junior team members actively seek your guidance and report feeling supported and learning from you.
Reliability & Dependability
Your consistent ability to meet deadlines, manage your workload, and be a trusted resource for the R&D team.
  • You rarely miss a deadline, even when things get hectic. When you commit to something, it gets done. Engineers know they can count on you to deliver high-quality work, even with minimal supervision. You're the person they go to when they need something done right the first time.

7Would you like it

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

What people enjoy
Seeing Your Work Come to Life

You get a real kick out of taking a complex CAD model or a vague concept and turning it into a tangible, functional object. That moment when a difficult assembly clicks into place, or a newly printed part performs exactly as expected, is what drives you.

You've just spent two days meticulously assembling a complex, multi-component sensor array. When you power it on and see all the indicators light up correctly, you feel a genuine sense of accomplishment.

Solving Tricky Technical Puzzles

You're energised by the challenge of diagnosing why a prototype isn't working, or figuring out the optimal way to manufacture a particularly difficult feature. You enjoy the process of systematic troubleshooting and finding elegant solutions.

An engineer brings you a 3D printed part that keeps failing at a specific stress point. You spend a few hours analysing the print orientation, material properties, and design geometry, then propose a minor design tweak and a change in print settings that solves the problem.

Making a Tangible Impact on Innovation

You want your hands-on work to contribute directly to the development of new products and technologies. You appreciate being an integral part of the R&D process, knowing your practical input is valued.

Your DFM feedback on a new product enclosure means the final design is not only more robust but also 15% cheaper to manufacture, directly contributing to the product's commercial viability.

What frustrates people
  • The soul-crushing feeling of a 24-hour 3D print failing at 98% completion, wasting a day and expensive material, especially when you've double-checked everything.
  • Receiving vague, incomplete, or contradictory requirements from engineers who expect you to read their minds, or worse, change their minds mid-build.
  • The project-halting wait for a single, critical component that is back-ordered for six weeks on Digi-Key, completely derailing your carefully planned schedule.
  • Being seen by some as just a 'printer operator' or 'CAD jockey' instead of a valuable technical contributor whose practical feedback can save the project from costly mistakes.
  • Engineers making 'one tiny change' to the CAD model that requires you to completely redesign the test fixture you just spent a week building, often with little appreciation for your time.
  • The constant tension between the need for a 'quick and dirty' prototype for a demo and your desire to build it robustly and correctly, knowing the 'quick' version might become the 'final' version.
  • Lab politics: Navigating who gets priority on the high-end CNC machine or the new resin printer when multiple urgent projects are vying for resources.
What this role does not give you
  • A predictable, unchanging daily routine – expect curveballs and shifting priorities.
  • A clear, linear path where every prototype you build makes it to production; many innovative ideas fail, and you'll be building those failures.
  • A purely theoretical or abstract role; this is very hands-on, practical work.
  • A role where you're solely responsible for the 'big ideas'; your job is to make those ideas real and robust.

8Who you work with

This role directly accelerates our R&D pipeline. Your ability to quickly and accurately produce functional prototypes, identify design for manufacturability (DFM) issues, and troubleshoot complex build problems means our engineers can iterate faster. You'll reduce material waste, cut down on rework, and ultimately help us get innovative products to market quicker. You're essentially a force multiplier for our entire R&D department, ensuring that the theoretical becomes practical.

9What you need before you start

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

  • Proven hands-on experience (5+ years) in a dedicated prototyping, R&D, or advanced manufacturing environment, working with a variety of materials and processes.
  • Demonstrable expertise in 3D CAD software (SolidWorks preferred) for designing, modifying, and analysing complex parts and assemblies.
  • Extensive practical experience with at least two major rapid prototyping technologies (e.g., FDM, SLA, CNC machining), including machine operation, maintenance, and troubleshooting.
  • A strong portfolio or examples of complex prototype builds, test fixtures, or DFM contributions you've made.
  • A solid understanding of engineering drawings, including GD&T, and the ability to measure and verify part accuracy.
  • Excellent problem-solving skills, with a track record of systematically diagnosing and resolving technical challenges independently.
  • The ability to clearly communicate technical information and provide constructive feedback to design engineers.

10What to practise next

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

Advanced Metrology & Inspection Techniques

As designs become more complex and tolerances tighter, basic calipers and micrometers won't always cut it. We need to move towards more sophisticated measurement and inspection methods to ensure prototype accuracy and validate DFM feedback.

CMM (Coordinate Measuring Machine) Operation · Optical Metrology · Statistical Process Control (SPC) · Reverse Engineering with 3D Scanners

  • This week: Research different types of 3D scanners and their applications in prototyping.
  • This month: If available, get training on our internal CMM or optical inspection equipment. If not, find online courses.
  • Month 2: Practice using a 3D scanner (even a phone-based app can be a start) to capture and analyse simple parts.
  • Month 3: Propose using advanced metrology for a critical prototype inspection to validate its accuracy.

Quick win: Watch YouTube videos on how CMMs and 3D scanners work. Understand the difference between accuracy and precision in measurement.

Simulation & FEA (Finite Element Analysis) Basics

While engineers do the heavy lifting, a basic understanding of simulation means you can build prototypes that are more likely to succeed the first time. You'll be able to interpret simulation results and even run simple analyses yourself to validate your DFM suggestions.

Stress & Strain · Boundary Conditions · Meshing · Interpreting Results

  • This week: Explore the basic simulation tools available in SolidWorks (e.g., SolidWorks Simulation Express).
  • This month: Complete an online tutorial on introductory FEA concepts and how to set up a simple static stress analysis.
  • Month 2: Work with an engineer to run a simple FEA on a prototype you're building, comparing your DFM intuition with the simulation results.
  • Month 3: Start using basic simulation to validate your own test fixture designs before building them.

Quick win: Watch some introductory videos on YouTube about 'FEA for beginners'. You don't need to be an expert, just understand the basics of what it tells you.

11Staying current once you are in

What people here do to keep up
  • Attend industry workshops or webinars on new rapid prototyping technologies, advanced materials, or DFM best practices.
  • Take online courses (e.g., Coursera, Udemy) in areas like advanced CAD techniques, basic electronics, or Python for data acquisition.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, some parts of prototyping can be a bit of a grind. But what if you could offload some of that tedious work to AI, freeing you up for the really interesting, hands-on challenges? We're not talking about robots taking over your job; we're talking about smart tools that make you faster, more efficient, and frankly, better at what you do.

In Research and Development, every minute counts. AI isn't just for software engineers; it's rapidly becoming an indispensable assistant in the physical lab too. As a Senior Prototype Assistant, you'll be at the forefront of using these tools to accelerate design, streamline fabrication, and even automate parts of your documentation, giving you more time to focus on the complex, creative problem-solving that truly matters.

Generative CAD Design

Use AI tools, like those found in Fusion 360, to automatically create optimised, lightweight mechanical parts based on specific load cases, material constraints, and manufacturing methods. It's like having a super-smart design assistant that can explore thousands of design variations in minutes, helping you find the strongest, lightest, or most manufacturable solution. You'll feed it the requirements, and it'll spit out designs you might never have thought of, saving you hours of manual iteration.

Smart Print Monitoring

Deploy AI-powered monitoring software, such as Obico or The Spaghetti Detective, that uses webcams to watch your 3D prints in real-time. It'll detect failures like 'spaghetti' or layer shifts, automatically pausing the job to prevent wasted time and expensive material. Imagine setting a 24-hour print and knowing AI has your back, ready to intervene if something goes wrong, instead of finding a pile of plastic spaghetti the next morning.

AI-Powered Datasheet Analysis

Use AI assistants to rapidly ingest and summarise lengthy technical datasheets for electronic components or new materials. Instead of sifting through dozens of pages, you can ask direct questions like, 'Compare the tensile strength of these three ABS filaments' or 'Find a MOSFET with these specific parameters and a breakdown voltage of at least 50V.' It'll give you the answers in seconds, making component selection much quicker and more accurate.

Automated Test Report Drafting

Feed raw numerical data from your test equipment (e.g., CSV logs from LabVIEW or Python scripts) into an AI model. Prompt it to generate a first draft of a test report, complete with summary tables, charts, and an executive summary of the findings. You'll still need to review and refine it, of course, but it'll take away the pain of starting from a blank page and save you hours of documentation time after each test cycle.
