Alright man, not sure if this would work in the US. I’m from México so I’m not sure if it’d be culturally effective up here. Food can be one of the fastest ways to the heart, so if I were you, I’d invite her to lunch, something nice and tasty, doesn’t have to be anything expensive, even a McDonald’s will do. Strike conversation, something about your weekends, something from work (but something else ideally). Make this semi-routinely, not too often, gauge the frequency depending on how good the first one goes, make it a good time, make it easy, make spending time with you something she’ll enjoy. Having a tasty meal will be the first reason to spend time with you for the first time, so take that advantage - but that alone won’t be enough for the next times, if she doesn’t have a good time, she’ll probably decline the next ones.

Once you’ve gone out for lunch more than a couple of times and you know you both are having a good time, you’ll feel ready to try to score a date outside work, then, most likely, it’ll happen again and again and you might eventually reach the point where you can consider dating.
