Some jobs appear here, I have recommended the PLC Jobs to several recruiters.
Thre are the big boards that include PLC, etc:
careerpath.commonster.com
hotjobs.com
dice.com
ajb.com
Some othersthat I remember off hand include:
controljobs.com
sologig.com
control.com
automation.com
automationtechies.com
jobbank.com
jobsbank.com
jobsonline.com
jobsearch.com
A lot don't have much.
No doubt, others will ad some more.
I see a lot of the same jobs posted on different boards, and often on the same board by several different recruiters. It seems like these jobs don't get filled, or have a high turn over.
I like careerpath and a couple others, that are primarily newspaper ads. I have found a couple jobs with careerpath over the last 15 years.
Sologig was a joke. Might be okay for California IT programmers.
If nothing else, this thread should come up with a nice list.
