Gone Fishin,
Yes, we hire electrical engineers, but for the most part, the regular guys on shift are encouraged to make changes and create anything that will help production. Basically, if I told them I could use a rocket ship to help production they would let me. They also give us a lot of freedom to make decisions, and to even fail, as long as we are trying.
As far as circuit board design....again you could solder boards till doomsday. Realistically though, if a board has a problem we generally do not troubleshoot to the component level. If it is stopping production, hot swapping is way cheaper, and much faster. Once we are up and running you can bench test and troubleshoot the problem, and then re-install it during downtime.
If you are interested, Google Nucor Steel. They have not had a layoff in over forty years, even when companies in the same industry were doing so. They are a great company to work for, and they treat their employees like gold.
Hope this helps
Lets get some locals together and play some pinball!!!,
