Questions & Answers about Она работает у нас в качестве няни.
Why do we use в качестве here instead of как?
Both can be used to say "as" a certain profession, but в качестве (literally "in the quality/capacity of") is a set phrase that sounds slightly more formal or official. You could absolutely say Она работает у нас как няня instead.
Why is the word for nanny (няня) in the Genitive case (няни)?
The phrase в качестве always requires the following noun to be in the Genitive case. If you used как instead, the noun would stay in the Nominative case to match the subject Она (so it would be как няня).
Why is "for us" translated as у нас and not для нас?
У нас (literally "at our place" or "with us") is the natural Russian way to say someone works at your house, your company, or on your team. Using для нас would sound like she is doing the work as a favor or specifically for your benefit, rather than simply being employed at your place.
Can I use the Instrumental case here instead, like работать няней?
Yes! Saying Она работает у нас няней (using the verb работать directly with the Instrumental case) is actually the most common, natural way to express someone's profession in everyday speech. Using в качестве няни just adds a slightly more formal "in the capacity of" flavor.
