Guys I need some advise

I am British National and recently got an offer from an employer in Switzerland. My wife is non-EU national but got indefinite leave to remain visa status in UK, who is living and working in UK for past 5 years.

My questions

1. What kind of spouse visa, should I apply for her?

2. Is she eligible to work in Switzerland?

Please do clarify if anyone knows about this or gone through this situation before.
