If the job is “good” and if “things are going well” the general rule of thumb is to stay at least two years. First year for you to learn everything and go through the complete yearlong cycle. Second year for you to take the initiative, to show that you were hired for a reason, and to see how much improvement you make compared to year one. Third year (possibly depending on specific situation) to show leadership skills and add value to the company (more than what you have to do as part of your job responsibilities).
I don't believe jumping from one company to the other would be considered a "job hopper". You need to be careful, however, not to change jobs too often, and have reasonable explanations of your decisions.
If you learn to do things that you need to do - then someday - you can do things that you want to do.
