In your free time, do customer support. Improve projects. Do code review. Build tools for other workers. Go see human ressources and ask to see what software they use. Read up on the best softwares, research them, and present them to your boss. Do things that you can assign to yourself on your own. You won't be able to assign yourself to interesting projects (the seniors are as bored as you and will have priority). But you WILL be able to assign yourself to interesting tasks. You need to watch out for depression and burning out from feeling meaningless. I was in such a position a while back and it wrecked a lot of parts of my life. Hard work is hard for you, but no work is even worst (when you are forced to stay in office).
