In large corporations, people have clearly defined roles and responsibilities. Junior level people are given clearly defined tasks and are expected to carry them out and as they grow more senior, they are expected to mature enough to take on more and more nebulous goals and work out what tasks are necessary to accomplish that goal by themselves. In a start-up, it's more the case that everybody is expected to do whatever they have to in order to keep the ship from sinking. There is less structure and supervision and employees are given the latitude and responsibility of what would be a rather senior role in a large corporation right from the beginning. That's the culture shock you're experiencing right now and only you can decide whether that's a role that will allow you to flex more of your talents or whether it's too ill-defined a role for you to be successful in.
