Yup, they do check past associations and references. So there’s no way the Walker campaign wouldn’t have known about her amnest work.
There is a question of whether Walker hired her because of her amnesty work, or because she is good enough despite that work to risk a voter backlash.
There’s a third option as well: this was a tactical move to deny her skills, experience and abilities to one of the other campaigns. Building a Presidential campaign team is a lot like playing Monopoly: you don’t want to just buy properties for yourself, you want to buy properties to deny them to others. If she’s really that good, it would probably be right to hire her so she doesn’t sign on with Jeb.

I’m always looking for the people they DON’T list as references like ex-wives / husbands, former landlords, people they were involved with lawsuits with, business relationships that went south, etc...: )
