When I got 35 years of experience, I started to act independently. "I'm not heavily loaded right now. Out of all the things I could do, which one is most important?" Then I'd work on that.

If you don't feel you're at that level yet, the fact that you're bored indicates that you're ready to work on bigger things. Tell your boss that. "I'm really bored doing the same old thing. Do you have anything more challenging I could work on?" If the answer is no, then you're dead-ended at that company, or at least on that team. Look around. There are places that will let you (and expect you to) do more.
