I'm a 50 year old bloke, who has spent 25 years in Sales, Marketing, and Product Management.
This has been in technical products - mostly test, instrumentation and metrology, though I spent some time working on Computer Peripherals during the early 1990's.
From 86 to 90 I held various roles with Bryans Instruments - manufacturer of various types of recording devices: x-y plotters and high speed paper recorders, also computer graphical plotters for laboratory, industrial, and military applications.
From 90 to 91 I worked for Aristo - manufacturer of vinyl cutting machines and digitisers - as a salesman. Worst job I ever took - taught me hugely about marketing mix the hard way!
From 92 to 98 I worked for Digitron Instrumentation limited. Firstly in field sales, then as Product Manager. While Product Manager, I developed the concept of the 2000 series products. The 2000 series is still in production 15 years later, it rationalised a huge product range into series of modules increasing production flexibility, improving delivery and customer service, and reducing production costs and stockholdings dramatically.

The above range is made from 1 case moulding ( in three colours ), a couple of main PCB/displays, a selection of sensing modules ( thermocouple, PRT, pressure, thermistor, humidity ), and a range of keymats. The rubber "boot" is an accessory. to contact Digitron - Click here.
From 98 to 2011 I worked for Schlumberger RMS division, who became Actaris, who became Itron.
Amongst other activities, I was marketing lead on the development of the "ACD" unit meter project - See https://www.itron.com/brasil/en/productsAndServices/Pages/EU%20Series.aspx
From 2011 to 2012 I worked for Engage Consulting, as a specialist in standardisation on contract to Sensus.
