I have had a similar experience. My current strategy is to find a place where I am the least useful person in the room, over time my competency will expand until I stop being challenged. Once that happens move on to another place where I am the dumbest in the room again. If you are currently bored/unchallenged I would say to implement some automated testing, then go to your manager with your honest feedback. They might find a better fit for you or give you more responsibilities.
