Bismihi ta'ala
It is permissible to work as a dish-washer in a restaurant that could server alcohol, but regarding washing the utensils/cups that are used for alcohol, if doing such a thing is a preliminary for the serving/drinking of alcohol, then such a job would be haram. The income earned for such a thing would also be haram.
And Allah knows best.
