When you work as a caretaker, you look after a house or a piece of property. The caretaker of a grand old estate might live in a small cottage on its grounds.

A caretaker might make small repairs to a house, weed a property's flower gardens, or mow the lawn. Some caretakers live in the house they care for, often during an off season when its main inhabitants don't stay there. You can also use the word to mean "caregiver," a person who takes care of someone who's elderly or ill, or to refer to someone who looks after animals.

Since this job falls under the umbrella of "semi or unskilled manual workers", it does not seem plausible that the caretaker would mean "caregiver" or anything else requiring some sort of formal education.
Hence, I propose this translation.
