We are an expat family who have lived in Hong Kong for 8 years. We are looking to replace are current helper who does not perform her basic duties such as taking out garbage and cleaning the bathrooms, washing the car etc. We have 2 small children and would ideally like our helper to play with them and help with their learning development. Ideally we are looking for someone with  a nursing or teaching degree. Must be organised and proactive and be able to work unsupervised. There would be some travel with the family required. Must be fluent in English and we will test for this at the interview. Please bring all educational achievements with you to the interview and be on time. Failing these things will result in immediate exclusion. We need someone who is active and fit.
