I am an Business Intelligence Analyst at Fortune 500 company. I think its really good job for someone who stutters. You need some technical knowledge and you spend quite a bit of time working alone not talking to anyone and the rest you spent on meetings which is great as you are not completely isolated, but your work does not depend on talking and people basically value you for your skills and ability to deliver not to talk. To get it you "just" need good knowledge of numbers and some stuff like excel, sql etc. People in there expects that you might be a bit shy so they are not surprised.
