In Job, Satan (ha-satan) is identified as one of the angels (sons of God) on two occasions. His job was to accuse and disrupt, to tempt so that, as Judaism explains it, man can make choices.
Finally, you'll have to take the issue up with Judaims. They emphatically deny that Satan is a fallen angel, that angles can rebel,or have free will, and emphatically assert that as far as Judaims is concerned Satan is a loyal angel of God.
Nowhere in the OT is there any connection made between Satan and Lucifer or satan and the 'devils" (as KJV calles them), or demons.
You also must take into consideration that Jewish demonology and anegology was notshared by the priestly caste of Sadducees who believed neither, and whose Canon was the Five Books of Moses.
You forgot the Psalms 109:6 and Zech. 3:2, "And the LORD said unto Satan, The LORD rebuke thee, O Satan; even the LORD that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire?" quotes.
What is left of Judaism today is a corrupt religion, from a true Christian perspective. They do not worship the one true God which means that their minds are darkened. Those Jews who where chosen of the Father and Son became the foundation of Christianity and everything that encompasses, including the theology of Satan. The things we believe about Christ, the resurrection, Satan and everything else has been handed down to us from our Jewish founders.
Gentiles are grafted into the belief structure established by our Jewish founders. You seem to be saying Judaism and Christianity were two seperate religious beliefs. This is not the case.
