Ability to understand not just the language and project you are working on, but the system and how to adapt or troubleshoot when met with challenges you don't understand. The ability to convey concepts and mentor people when they are in a bind. Knowing when to take a step back, look at the problem a new or ask for help. Some of that comes through experience, but I've met people with time put in that can't get their head around more than their niche. (I'm talking general programming here, not deep specialization)
