Mechanical engineer with 16+ years delivering production hardware across light electric vehicles, bicycle components, and structurally demanding consumer products. Founder of Carchrie Engineering.
Mechanical engineering consultancy · Sydney
Mechanical engineering for products where failure is expensive — structural validation, DFM, and engineering judgement before you commit to prototypes, tooling, or production.
Typical engagement points
These are the moments where the cost of getting the engineering wrong is highest — and where our judgment adds the most value.
Not sure where to start?
A fixed-fee engineering consultation for founders and product businesses exploring new hardware. 60-minute session with written summary — fixed fee, contact us for details.
Individual services
If you already know the service you need, we quote and deliver it as a standalone piece of work.
Why we catch problems others miss
That perspective changes what gets caught before production.
Failure analysis & independent review
Independent root cause investigation for field failures, warranty disputes, or insurance and legal matters — structural analysis, root cause findings, and a written engineering opinion — independent, with no stake in the original design.
Confidential. Independent technical opinion supported by engineering analysis and written documentation.
Hardware delivered
A selection of projects we can share — much of our work is covered by NDA.
Client feedback
"I want to keep him all to myself. He's been an exceptional partner — understands the domain and communicates it in a way I can follow, which has been instrumental in moving the design forward. Reluctantly, I highly recommend."
"Carchrie Engineering was recommended to me by a business colleague. I had a clear idea of what I needed but James added a lot of value with his collaborative ideas. He was open to meeting my tight deadline, plus he found me someone to build the product. Six stars."
"Excellent work in creating the designs for our project. Very helpful in providing all the drawings required to produce the wooden panels."
"As usual, delivered on time to the high quality needed. Working with James is always easy and stress free. Responds in a timely manner, is professional, helpful, and his services will continue to be used as and when needed."
"Fantastic work — prompt, very easy to work with and produced exceptional results. I would and will absolutely recommend his expertise to anyone who needs it."
"Very happy with the feedback which helped us make a decision on imported parts. Able to operate under a somewhat vague set of parameters and get the job done. Would hire again."
