“There was once a man in the land of Uz, whose name was Job.”
He was called Job, a man from Uz, not Oz, although that name may have come from here. It has a fairy tale tone with the once upon a time in a far away country tone in this opening sentence. Uz was probably in Edom, south of Israel. In Genesis, chapter 10, Uz was the first born son of Abram, whose father was Shem, who in turn had Noah as his father. Thus Uz was the great grandson of Noah. There also was a place in southern Syria with this name. Uz was the first born of Nahor and Milcah, the brother of Abraham in Genesis, chapter 22. Uz was also a son of Dishan, who was the son of Seir, the Horite, in Genesis, chapter 36, and also in 1 Chronicles, chapter 1. Thus this country of Uz could have been named after any of these people who were descended from Noah (Shem, Abram) as a great grandson, Abraham (Nahor) as a nephew, or from Seir (Dishan) as a grandson of a Horite. The closet connection to Israel would be as the nephew of Abraham. Definitely, this is not in Israel or a descendent of Abraham, Isaac, and Jacob, probably northern Arabia or southern Jordan.
