I went there, typed in "developer" in the search box, and got dropped on a map zoomed in on the Kansas/Oklahoma border and a message saying my search didn't match anything. Took me a while to notice the "zoom out on the map" part. Not sure why I landed in the middle of nowhere in the US, I'm located in Europe. In any case, super unintuitive.
Also, this might be an American thing I'm missing, but which (if any) option of "Pod Office Layout" or "Closed (Cubicle) Office Layout" corresponds to "proper walls and a proper door"?
I'd also suggest adding a filter for minimum salary.
Hope this helps.
