If your wife loses her permit (e.g. after completing her studies) you will need to leave the country as well even if you have a job, your permit is dependent on hers even if you have a job and earn enough money to support you both.
Alternatively you will have to be rehired as a fresh non-EU person with the whole circus of your employer having to prove that they could not find a Swiss/EU person for your position. That is very hard to do.
