F1 students are allowed to work full time in summer ie. as an intern. During the last semester, if you have a reduced course work, you can work full time again for a semester. Finally, after the degree is completed, you are allowed one year of OPT (Optional Practical Training). THe two that I mentioned earlier (while your degree is on) come under CPT (Curricular Practical Training).
I assume that you have already graduated then. In that case, your university's career center is the best place to start off with. If that doesnt work out, check out career fairs of neighbouring universities. Some of the companies I know are hiring in the coming semesters are Cap One, Sapient, MicroStrategy, Bearing Point, Deloitte, Freddie Mac/Fannie Mae, IBM. THat should give you a decent starting point. A lot also depends on your location.
