G ´day
I guess you will not have heard the word Domestic Goddess either
Domestic Technician is just a title for someone who does all the household chores like cooking, cleaning, gardening, shopping, D-I-Y, etc, etc
Back in my day workmen from the Town Hall/Council who cleaned the streets and emptied the publics garbage /trash from their homes were called dustbin men now I think they have been renamed as Garbage Disposal Officers´
