My first job was as an RF (microwave) bench technician. My initial schooling was at a trade school for electronic technicians.

It was all about fixing bugs; often, terrifying ones.

That background came in handy, once I got into software.

I started life as an engineer. Try reverse engineering why an electrical device your company designed (industrial setting, so big power), occasionally and I mean, really really rarely, just explodes; burying its cover housing half way through the opposite wall.

Won’t fix doesn’t get accepted so well. Trying to work out what the hell happened from the charred remains isn’t so easy either.
