I have to say this is the very first time I've ever seen someone apply for a job anonymously.  It makes me wonder how serious you are about helping this person find a job.  Do interested employers have to post their name and phone number to a public forum or can they just PM Anonymous?

Aren't live-in housekeepers an occasion of sin?

Not necessarily.  Such was quite common in the medieval ages, and it is still found in many traditional Catholic societies.  As long as proper decorum is used, there should not be a problem.   :)

A St. John Vianney sermon:

To Their Shame It Must Be Said

     YOU SHOULD never put your maidservants or your daughters to sleep in quarters to which the men will be going in the morning looking for food. This is something which, to the shame of fathers and mothers, must be said. These unfortunate children, or servants, are confused and embarrassed getting up and dressing in front of people who have no more religion than if they had never heard anyone speak of the one true God. Often, even, the beds for these unfortunate people have no curtains around them.
     But, you will say to me, if we had to do all the things you say, there would be an awful lot of work to do.
     My friend, it is work which you must do, and if you do not do it, you will be punished on account of it: see….
     I know very well that you will do nothing, or practically nothing, in respect of what I have just been teaching you. But no matter. I will always continue to tell you what you ought to do. Then all the wrongdoing will be yours and not mine….
     When God comes to judge you, you will not be able to say that you did not know what you should have done….
     I shall remind you of what I am telling you today.

I think people are being overly critical.  The poster wanted to be anonymous, for her own reason.  The anonymity could mean anything ranging from not wanting to jeopardize her current employment to trying to get away from an abusive situation.  This person seems to be attempting to find a traditional Catholic family to live with, which mean she is trying to find people who will share her values rather than lead her astray.  Real life is expensive and it seems like she is trying to remain in the Society.  I am no where near the area so I can be of no help.  I really feel that we need to build, nourish an support our community. Since joining the SSPX, I have always been shocked to see how many people are ready to point fingers and try to be holier than thou.  A little kindness, especially online, can go a long ways.

As far as I can see the only person to question the anonymity of OP did so anonymously!

That is what is so annoying about the Anonymous Posts section. One never knows who is saying what. I would like to see a system where the anonymous OP would be AP1, the first anonymous responder would be AP2, and those who have no need for anonymity to post under their own name. Just a thought.

for sure--about t hat lack of charity stuff
no wonder Jesus said few make it to Heaven. So few are willing to give up what they think is so clever snarkiness, etc...
This is why the world is so unchristian.. Christians aren't even Christian
