My view as a burgeoning senior dev is that the "senior" bit is generally less about coding and more about domain knowledge.
Understanding the business processes of your industry, how to solicit feedback from and interact with end users, how to explain things to management/sell on ideas.
If you put a junior dev in front of a panel of executives and ask them to explain requirements for a project odds are quite high they will info dump tech mumbo-jumbo. A senior should be able to explain risks, benefits, timelines, and impacted areas of the business in a manner that non technical people can easily grok.
