To build on the suggestions other people are making, I would say that one thing I look for in the transition from to "senior" is the ability to make the people around you better. At the junior/entry level, a lot of your focus is about consistent delivery for yourself. As you move up the ranks, its about making you and your team better.

That could be removing roadblocks by flushing out designs and specs like other people have mentioned, or finding better processes and practices to make the team more effective. Of course, there is also the proper introduction of new technology or techniques to raise the company forward as well.
