David McKenzie BE(elec), M.IEEE, MIEAust.
Since graduating from the University of Canterbury in 1997 and prior to starting McKenzie
Electronic Design, David had gained over 10 years experience in the telecommunication and
medical device industries.
David worked with Cochlear for nine years leading the electronic design work from initial
concepts to the final formal verification of two sound processors. The Freedom sound processor is
a multi-award winning design and the recently released Nucleus 5 sound processor is also
expected to win awards.
Being the original electronic engineer on the Freedom sound processor project team, the project
team grew around David. On the Nucleus 5 sound processor project David was the lead design
The sound processors are a product that is a cross between being a consumer product and a
medical device. As a result, the product involves styling and aesthetics for general consumer use.
David has been involved with the full product design life cycle including;
* introducing new suppliers and new production processes, and resolved various technical issues.
* working with suppliers and sub-contract manufacturers, providing the supporting technical
documentation, prototype test procedures and supporting prototype test software
* having the product certified for EMC (CISPR), and CB certified
The full product design life cycle includes; concept selection, requirement breakdown, robust and
tolerance design techniques, simulation, characterisation, design specifications, prototypes,
design reviews, DFMA, verification and certification.
David left Cochlear to start the contract engineering business McKenzie Electronic Design, which
provides the service of his product design skills from years of experience.
“By contracting in more industries I believe that I can have a greater positive impact on people’s
lives and in helping other businesses move ahead.”
In 2020 in the midst of the COVID-19 pandemic, David has made a move to DTI, taking on the
position of Lead Hardware Engineer.
