Western family of 4 with dog looking for helper in Singapore

We are an American family of 4 with 16 year old twins and a large, sweet dog. We need someone to take care of the household cleaning, laundry, dog walking (mainly when we are gone), and some of the cooking/shopping. You will have your own small room and bathroom in a nice river valley penthouse condo in Singapore with nice rooftop deck to hang out on.
