Pros
In general, the pay scales are good. The technology and diversity of what you do can keep you challenged and motivated. There are opportunities to travel or to re-locate in a wide variety of global locations. They are also fairly flexible with work schedule. Though not as cool as an apple or a google, Automation still has a pretty high coolness factor. We control almost everything from linear accelerators to automotive assembly and hog processing.
Cons
Upper management has a great tendency to steer off from the focused path of specific products or direction which can be frustrating. Too many managers driving product lines. They do not typically promote in group or team .. which means you need to change job functions and often locations for real promotions. If you want to manage your group .. you have to leave it and come back 3 years later. They put a huge emphasis on sales experience for higher management jobs where sales people tend to get overwhelmed by the technology.
