Fire them immediately. I've been in this position before and the hire dragged down team productivity for almost a year as we struggled to find something that he was competent at. Wasted untold hours assigning other skilled devs to help him because we were sure that all he needed was a "bit more guidance." After 9 months of this, our manager finally bit the bullet and he had to go. In nine months, we could not find a single task that he could be trusted to do and he had shown no improvement in that time. Learn from our mistake!
