What job can a 17 year old with MBA get?

I'm 17 and I have a MBA from McGill University. I want to work in the corporate world in either New York or London but I want to know how can I get a job there at my age. I refuse to take a job shuffling papers or as someone's secretary. So I decided to turn to answers to see your recommendations. By the way, I am interested in the banking and financial services sector. PLEASE HELP!
