Afraid of Taking This Risk

So there's this girl. She's two years above me, but we work together in an extracurricular club; she has a leadership position and I'm in the group for the first time. I think I've liked in her since day 1 essentially, about two months ago. We talk while we're working, but it's not much more than chat. Now, in my short life I've mostly been interested in guys, with only a couple (non-serious) exceptions, and for a long time I had really strong feelings for this one guy that sort of "covered up" everything else. But now that that's over, I definitely feel something for this girl, and I really wish I could pursue it, if only for a little while. I've never been in a serious relationship before, though, and I've never talked about my apparent bisexuality with my friends. I know I shouldn't expect much out of this opportunity, especially because she's going to graduate this year, and I don't really have much faith in long-distance. However, I can't help but think about her. I would like to see where it could go, but it just seems risky to try to be anything more than coworkers. What I'm most worried about is the dynamic between us if she's not interested. I've only known her a short while, so it might seem a little strange for me to ask to get to know her better, though I don't think that's abnormal in most circumstances. But, add to that that she's older than me and that she's in a leadership position, plus I don't know if she is interested in girls... It seems like tough odds. I know that I'm not afraid of plain old rejection, but I suppose what I am afraid of is that she'll be "weirded out" by any advance I make, and that it'll make working with her awkward. I don't want to sacrifice the fact that we work well together. Odds are she just wouldn't consider a relationship with a girl, or with someone younger than her, or with anyone given that she'll be leaving by the summer. I know these things, but I'm worried that I'll regret never giving it a try. I really do like her quite a bit. I suppose my main questions are, Should I risk our smooth working relationship over this? Or should I just move on with my life because it's not going to happen? Thank you so much for reading, I hope you all are well.
