I am an electronics engineer - but my job isn't really related to pinball per say as I am more involved with assisting with research on various projects that range from printable electronics, carbon nanotubes, graphene, batteries, solar cells and a couple others.

But on the other hand I guess it does somewhat count since I handle silicon wafers almost on a daily basis which is essentially the starting point of all microchips today.

I learned about pinball by just diving into them - IMHO they are fairly simple, but it's all about the programming, the bulk of the electronics is mainly for the input and outputs. Of course I found this place a couple years later and it has made my life much easier (taught me a few of the 'tricks of the trade' so to speak).

...maybe in the US...
