In my view, the dating website is a red herring. Why not approach the person directly at work (without mentioning the dating site) as you would normally ask out someone? Whether this is considered harassment is dependent on your culture/locale (but when people get a couple in real life, someone has to ask out the other person!). In Southern Europe, it would be fine to ask out a person in your workplace with which you do not work together (of course, provided that you do this respectfully and with your employer's policy on that matter in mind). Most couples do meet at work.

Of course, read in the Internet the usual advice for dating on the workplace. You can find a lot on that in the Internet.

And, just to be sure: it is usually better to ask one out personally than to message them (especially if this would be through a company channel), of course.
