My reading plan is the "chronological" plan, which means it attempts to take me through the Bible in the order of the events--not the historical order of when they were written, or the traditional order in which the passages have been collected. Because the book of Job takes place in the land of Uz, we set it before Abram leaving the region.
From a literary standpoint, it actually works pretty well to make this transition. The first 11 books of Genesis are very clearly myth that, like Job, could not ever have been intended to be related to "actual" events on the planet Earth. Once we get to Abram, the story is likely not historical in the way a modern reader views the word, but I think is at least set as relating to events that transpire in a particular time and place.
The main thrust of job, in chapters 1-5 and frankly through out the book, is that co-creators or not, God is the Boss. Seemingly at the whim of the adversary, satan in Hebrew, God allow calamities to fall upon Job, up to and including the death of his children. Then Jobs friend talks about how God blesses the good, frees the captives, etc. I can't help but wonder how those who suffer must feel when we read similar scriptures from Isaiah. Although plainly a story, in the Book of Job, things get real.
And interesting component of Job is the conversation between Satan and God and the sons of God. The NIV translates these to angels. Um, okay. But the word is sons of God, and that term is used in Genesis to describe the people knocking boots with the Earth girls, in response to which God limited human life to 120 years. Religion evolves, and evidence of pretty radical evolution exists in our Bible. That's all I'm saying.
