It is definitely possible to make the transition into finance in an operations role at possibly quite a senior level. The skills are very transferable to operations, and more and more investment banks are looking to utilize six sigma methodology in order to reduce costs and improve process efficiency in a competitive environment.

Efinancial must have quite a few roles in the operations section. Try checking out http://www.findgradjobs.com – im sure there are some schemes on that website too which mention six sigma

Good Luck
