Hello Ruchi , Biomedical engineering is a one of the good branch, but frankly speaking as compare to other branches students rarely choice this branch. But it has good enough scope in India,  absolutely it is dependent on your interest. As per your specialization you have following options for the job designations

Physician

Manufacturing engineer

Software engineer

Researcher

Salary is also good enough in this field. Average salary is up-to 3.5-4 lacks.  And it increases as per knowledge and experience.

I hope it will help.

Thanks.
