Trying to find an on campus job at a school that didn't offer an assistantship

[danny1997]

Hey guys, 

I applied to UMBC for a PhD but was accepted for an MS as they have a policy to not accept recent undergraduates to their PhD program. I still would very much like to go to this program, especially with how well known UMBC is for their research in all areas. However, I was not offered a first semester assistantship and, as much as I would like to invest the money into this education, I would have to take in a great deal of new loans. That being said, I was told by the program director that many masters students find jobs in other programs and that the program may be able to offer some tuition assistance (although they will not know until about August). 

I am looking into on campus jobs but I am struggling to find any openings online. Has anyone had experience finding jobs outside of their department? How did you go about doing this, and do you have any general advice?

Thank you all so much for your assistance
