Apologies for adding another post, but I found more 'official' information about au pair employment for Geneve. Indeed it is much more tightly controlled with very specific details.
Thus, please refer to this information for Geneve, and don't refer to the Genevefamille info in previous post (cannot edit).
Specifics of the work permit (in English), see bottom of page:

Specifics of the standard contract, (in French):

In summary, there are some additonal criteria specified by Geneve compared to Vaud, ie. that the employer must insure the au pair against illness with a swiss insurance fund and must assume half the costs; the working conditions of the standard contract (wages, hours, etc) must be observed; the costs of schooling are the obligation of the employer; the language spoken by the au pair and the family and the region must be different; and the nature of the activities required correspond to the au pair placement, ie. no complex tasks.
The standard au pair contract goes further in specifying minimum wages; at least 4 hrs of schooling in french per week; the work cannot exceed 5 hours per day and 30 hours per week; the right to have certain federal/canton holidays off as non work days; specific requirements of the room to be provided (heat, light, furniture, privacy); medical/accident/pharmacy insurance to be covered; the social insurances to be covered; paid vacation days specified; etc.
For poster JC1, if you were employed in Geneva, you would not be within the law. It specifically prescribes work cannot exceed '5 hours per day'. However, I don't know if your Canton has the same equivant work requirements for au pairs.
