Check out the Main Line. It comprises the nicest suburbs in the area. Affordable enough on a dev-salary. Best place in the area for a family - very safe. And many companies line the Main Line up through King of Prussia (also a decent area).

If you want to live in the city, I highly recommend Logan Square/Art Museum area or Rittenhouse if you've got the dough. I lived around Logan Square for about a year and I felt incredibly safe even late at night. Northern Liberties is a great place for brogrammers - it was a little too much for me.

DuckDuckGo is the coolest company around that I'm familiar with. Tech scene is good. Tons of meetups.
