Should I do it, if he's married?

Met a guy who works at a shop i visit daily. For the past month he has been super friendly and flirty. After a search online turns out he is married, which explains why he hasn't crossed the line or asked me out. I am an HR manager and I want to hire someone friendly for reception as my employee... I know he is married, should that stop me from offering him the position?
