Hacker is fine, all job descriptions looking for a "ninja hacker" or for that matter any job descriptions prefixed with the word ninja should be ignored. I have never met someone serious about programming that liked to be called a ninja or thought of themselves as such. I have met many people who were very into start-ups but had no CS or Engineering background that loved to give themselves and others silly prefixes though. In a nut shell call yourself what you like, but be wary of those too interested in titles as they are probably trying to make up for something.
