Since I'm anticipating applying for Physics Teaching positions come next May, I frequently search online for the current opennings. Usually I'm annoyed with monster.com or careerbuilder.com since they give about 12 results and most of them tutoring or teacher placement companies.

However...today I used simplyhired.com and had 24 pages worth of results! The majority of them were actually physics jobs! I searched nationwide since I don't know where I'll be living, but you can certainly limit the results!
