Maybe you've outgrown your place of work. When your work isn't challenging anymore, it means that you are stagnating professionally - You are not growing. You can choose the easy path and stay in the same company or you can move on to another (better) one. I've been through like 8 software companies. As soon as I felt comfortable in a particular company; that was the time to hand in my resignation; unless it was a startup which showed potential then I would stay longer. Typically, when you join a new company, you should try to be the dumbest person in the room. If you're not, then this is not the company for you. Usually being exposed to different problem domains and tooling should be challenging enough for the first 3 months.
