ויש אומרים איוב בימי יעקב היה ודינה בת יעקב נשא כתיב הכא כדבר אחת הנבלות תדברי וכתיב התם כי נבלה עשה בישראל.
Some say that Job lived in the time of Jacob and married Dinah the daughter of Jacob. [The proof is that] it is written here [in the book of Job], Thou speakest as one of the impious women [nebaloth] speaketh, and it is written in another place [in connection with Dinah], Because he had wrought folly [nebelah] it, Israel.
ר' חנינא בשם ר' אבא הכהן בר' אליעזר פתח: למס מרעהו חסד.
מנעת חסד מן אחוך, היא נסבת לאיוב, שאינו לא גר ולא מהול.
R' Chanina said in the name of R' Abba the Kohen, son of R' Eliezer: "By one who withholds kindness from his friend". You withheld kindenss from your brother, so she will marry Job, who is neither a ger nor is he circumcised.
... נטל יעקב דינה ונתנה בתיבה, שלא יראה אותה עשו ויטול אותה לאשה, א"ל הקב"ה חסכתה אותה ממנו חייך לאדם ערל היא מתוקנת, הוא דכתיב למס מרעהו חסד, אילו היתה נישאת לעשו שמא היתה מגיירת אותו, כשנטלה איוב לא גיירה אותו,? לפיכך חסכתה אותה הרי בן מאירה בא כנגדה, וירא אותה שכם בן חמור.
Jacob took Dinah and put her in a box, so that Esav wouldn't see her and take her to be his wife. Hashem said to him: You have withheld her from him, [I swear] upon your life, she will be given to an uncircumcised man. That is what was written: "By one who withholds kindness from his friend". If she had married Esav, maybe she would have converted him, for hadn't she converted Job? Therefore, you have withheld her from him, so a cursed person will come to her: "And Shechem the son of Hamor saw her".
דינה בת יעקב נישאת לשבעה אלופים, שכם בן חמור, שמעון בן יעקב, איוב, נבל, דוד, טורנוסרופוס ור' עקיבא... אחר פטירת יעקב נשאת דינה לאיוב.
Dinah the daughter of Jacob married seven champions, Shechem son of Chamor, Shimon son of Jacob, Job, Naval, David, Quintus Tineius Rufus, and R' Akiva... after Jacob passed away, Dinah married Job.
And here are the sources mentioned in the questions with their (unofficial) translations:
11 [Dinah was taken out of Shechem's house]
"and they took Dinah". R' Yuden said: They dragged her out.
R' Huna said: A woman who copulated with the uncircumcised cannot easily leave him.
R' Huna said: She said: Where will I go with my disgrace? Until Shimon swore to her that he will take her (as a wife), and that is what is written: "and Saul the son of the Canaanitess" - the son of Dinah who copulated with a Canaanite.
(This is a subject of dispute between) R' Yehuda and R' Nechemia and the sages.
R' Yehuda said: That he has acted like a Canaanites.
R' Nechemia said: That she copulated with a Chivi, who are considered Canaanites.
And the sages said: Shimon took her and buried her in the land of Canaan.
