Look, I have a degree in semiconductors and optics too (and no masters). I did not get a job in my field. In a matter of fact, I started with anything to earn living. 20 years passed by, and I am in manufacturing working as a general worker/technician, but at least I make a living. My engineering skills are obsolete now. I suggest that you should make decision base on your economic situation. If you still have some cash, go South Korea, Japan, California or even China. If you are in U.S. look for small start up companies. Otherwise, grab any job to stay afloat.
Your have two Masters, then you should be a 'French Vanilla ' for recruiters.
