Chinese / Western family looking for helper

We are a loving family of 4, having 1 girl of 7 years old and a 1 baby boy of 5 month old. Both parents are working. The ideal candidate should have good English, willing to work, responsible and have good time management skills. Job duties include cleaning, cooking and baby care. If needed, grandparents can visit from time to time to assist. No need to do baby sit during night time. Whilst we offer Sunday off, our helper should be flexible with her day off and willing to adjust her holiday according to our requirements. We have a separate en suite helper room. Salary commensurate with experience.
