> it's getting harder and harder to find low-level work

That doesn't match with my (current job seeking) experience at all, the embedded market is really healthy at the moment. What sort of keywords are you searching on?

Good point, thanks for the correction. I recalled assembling RF and other analog circuits using breadboards in labs, but those were likely too low frequency to run into those problems.

Upverter has a nicer schematic editor and more social features, but doesn't have any PCB layout capabilities (at this time, at least.)

It looks like these are two layer boards, meaning you can route traces either on the top (red line) or the bottom (blue line) of the board.

have read that prototyping on breadboard doesn't work well.

That's definitely not my experience. Using a solderless breadboard may add more noise, but it's much easier to assemble and correct mistakes.
