I will be getting BS in biology in few months.

Other than going to graduate school, or other professional school,

Where should I search for a job?

I want to try to find a job in the field related to my major first.

I will be graduating in few months, and I'm really worried about my career plan.

 

Any advice will be greatly appreciated.

Have you talked to your academic adviser where you study? They usually have a good amount of resources and it's part of their job to inform you of this stuff. That being said there are search engines to try to find areas of your specialty though you may need advanced degrees for a lot of them:
