I am studying biomedical engineering, which is the direction of medical devices, what kind of career can I have and what can I do in a company?

Doing well, you can make devices and be an engineer. If you don't do well, you can only sell medical devices. Or repair in hospital equipment department, or manage medical devices.

Biomedical engineering, good schools of course, employment can be. This is actually nonsense, all professional good school employment is good.
