Many companies, such as Lexmark Intl, Playdom, Epic Systems, Wolfram Research, FedEx, etc. are looking for CS students for full-time and internship positions. See their job listings and many others on CCO Express: https://www.cco.purdue.edu/Student/

After you sign in on the student site, choose "Jobs & On Campus Interviews" tab across the top.
The tab has a pull down menu, choose "CCO Express OCR & Job Listings"
You may use several criterias to narrow your search, or search by Job Function.

Good Luck!
