Same boat
Zipperhead,
Your story rings almost like an echo to mine. 3 years ago I approached my supervisor and pointed a finger at our resident PI&C Engineer who is just now retiring and asked what I needed to do to get the job. The answer was, without hesitation, get your degree. I now have 3 years down at UWP, and am about half way finished. You will find that an Engineering Degree is not worth as much if it is not ABET accredited. You will also find that there will be groups willing to hire you, but your initial wage(and possibly later wage) will represent your education level. The difference here for me is huge. I presently do the job I aimed for, but am paid hourly rather than salaried, and am at a ceiling. When I finish my degree, the salary range will double. I think you'll find this true almost everywhere. If you are willing to travel, there are integrators that will hire you. I was not willing to do that. One thing I have learned since continuing my education, a solid technical background does not give one the ability to correctly design systems. I am just now beginning to follow Peter Nachtwey's posts. System modeling and design will become huge when you step into the design realm, and those are skills that classes like Calculus, Signals and Systems and the like will develop. Further, you will find that even if you do end up in an engineering role, you will still be behind the curve for promotions, etc. Already here we are seeing stipulations for higher level engineering positions or engineering supervisors required to have masters degrees.
What all of this boils down to is that I think you sound a lot like me, and I believe I'm going about my career pursuit the right way. There will always be a premium on education, and experience means less and less all the time. Anyone can have experience, and it generally doesn't separate a good tech from a bad one. However, an engineering degree is something that can and will separate you and put you head and shoulders above the rest. Not only will it prove your intelligence, it will also say something about your character, that when you start something, you finish it. Good luck.
P.S. Where in Wisconsin are you located, and where did you go to school?
P.S.S. Ironically enough, my wife is a nurse as well.
