I really like this girl but dont know where to start

A little bit of an introduction:
I'm not actually looking for a sexual hookup but more into looking forward to settle down,marriage & be happy with her for the rest of our lives. I'm working in a call center as a quality assurance officer & she's a new girl in the company working as a customer service staff. We're not in the same department, i first laid my eyes on her when i went to see a friend who's working in the same department as her, she's a real eye catcher. I learned her name from a friend, ransacked the HR data to get her employee details, listen to her calls & i have to admit that i really like her. I really wanna get to know her but i don't know where to start.

Constraints:
1. I'm a rank higher than her, so i don't wanna appear using my rank to tackle her. Also don't want her to accept me because of my status.
2. Going straight to talk to her is very difficult because most of the time she'll be engaged on the phone talking to our customers.
3. I have her phone number(from the HR data..LoL) but i don't think calling/texting her without her knowing me is a good idea.

And last but surely not the least, I'm a shy guy.

Please help me gurus!

hmm, I feel like you already have +1 because you work together. Do Not mention anything about listening to her calls, having her number or anything aka don't text/call her. You'll have to come up with an opening of some sort. I don't know how your work environment is but here is a shot in the dark: If it is slow in the office go up to her and say something about it being boring in there and then do a magic trick or some kind of Phase Shift game. You could also approach it with a neg, maybe about something she said that was funny or her voice sounding annoying.

Don't let yourself put her on a pedestal like that of wanting to marry her when you haven't talked to her before. It will only make it harder because you'll be afraid to fail and then you'll mess up. Just be calm and smooth and think that she is lucky to get to know you.

Somehow,something happened I went for a vacation(arranged by my dude friend) with the girl about 2 weeks ago. 2 guys & 2 girls went as friends, it was really fun. I played cool all the way. Before the vacation we're just 'hi bye' office colleague. Now we're getting closer. We don't have each others number until after the vacation. Guess what? she asked for my number. One day I offered help to send her home after work, before she left my car she asked for my number. Yiihaaa. I took her to my soccer practice the other day, then went for a nice dinner afterwards. We talked a lot about each other. It was really fun. I sees ioi. I can feel the chemistry. But now I don't know how to proceed. Is it too soon to tell her I like her. Should we just continue getting closer & closer(bring her to my soccer practice once in a while, maybe movie or dinner etc.) & let time decide. At this point, I'm just afraid that I might do the wrong thing. Being too quick might scares her off. If I wait, I'm afraid I might lose her. What should I do? Also if it's already a good time to make a move, what's the best way to tell her that I like her?

sh1t. i think i screwed up pretty badly today. i'm going to see my friend's new born baby today after work. i asked her to join me. at first she said yes, after a while she said she said she cant join me coz she has some other thing to do.did the new born baby thingy gave her any wrong idea? arghhhh...

no your fine. your over thinking this waay too much. just be calm and collected which shows your confident. Just enjoy hanging out with her to keep it from being awkward. It sounds like your definintely getting ioi's so keep it up. When you think about messing it up you will mess it up. Just be yourself and don't overthink it

It sounds like you are definitely doing good. She is interested in you from what it seems, but I agree with the replies, do not open up to her and let her know you are highly interested in her. Let your actions, such as flirting a little, asking to hang out, and getting closer, show her you are interested.

Keep her interested in you. It sounds like her coming to your soccer practices is definitely a plus. She finds you interesting in that sense which is awesome.

Good job buddy. Take it easy, don't over think, and you got this. Show confidence by telling her you are taking her to the movies or for some coffee. Don't ask. I tend to have better luck by just saying to a girl, "We are going out for drinks Friday night" rather than saying, "Would you want to grab drinks on Friday night?"

My supervisor at my job is a 40ish year old female and I talk to her about my adventures with women and what I learn on the way. The one great piece of advice she gave to me is when asking a girl to hang out, always be direct and to the point because women HATE making decisions. They worry about too much when it comes to that kind of stuff, such as;
depending where we go, I have to decide what to wear, how to act, how to dress and do my hair and my make up, and I have to be ready at this or that time. Guys don't think that like. Guys are like, okay 7:30 means 7:30.

So, when it comes to it, be direct with hanging out, it definitely shows confidence and control (not the bad kind of control).
