Did you create your characters on Tribble or did you transfer them?
If you made the character on Tribble, was it before or after October 20? That patch made some changes to where you start as a Klingon and might affect how you get your bridge officers.
I created my Klingon directly on tribble when the KDF side was opened up. Like Rougemaster and the others have pointed out, the Bridge Officers are not being given as you level. I am at level 47 now and the only BOffs I have are from the DOff assignments (and the ones you get when you create a KDF character).
