Work abroad as an Au Pair and Nanny in Celrà, Girona Spain for >1 year in Pedro's family

The job of the person who comes with us will basically consist of taking care of the children: taking them to school at 9, picking them up from school at 16:30, being with them playing or doing homework, taking them to basketball when It is their turn to do this, help them with the bathroom and prepare dinner, and be with them until I get home at approximately 8:00 p.m.
Also due to my new personal situation, the new aupair will have to take care of the children every other week. That is, one week she will take care of them because they will be at home, and the following week they will be with my ex-wife, so she will have a lot of free time. The only specific chore in terms of housework I ask for help with is ironing the clothes. I don't have much time to do it due to my work schedules, and I also do it awful!
We consider our aupair a member of the family, and as such I appreciate collaboration with the daily tasks of the whole family, such as setting or clearing the table for example. Here we all help and we all collaborate.
As for the time spent with the children, I would like that time to be really dedicated to them and the person who is taking care of them does not spend more time looking at the mobile phone than at them or spending more time smoking in the garden than playing with them, So I ask that while you are with the children you do not smoke or play with your mobile.
