When was Job alive?

The first chapter of Job describes a man who was favored by God (Job). > 1 In the land of Uz there lived a man whose name was Job. This man was blameless and upright; he feared God and shunned evil. 2 He had seven sons and three daughters, 3 and he owned seven thousand sheep, three thousand camels, five hundred yoke of oxen and five hundred donkeys, and had a large number of servants. He was the greatest man among all the people of the East. For whatever reason, I'm assuming he was pre-flood period, but was wondering if there's an estimated time-period he was alive. Looking for potential years (6000BC or something) but also any correction to my assumption it was pre-flood.
