Is it obligatory to inquire about a factory's dealings with bank interest or its insurance on its properties when applying for a job? And is working on implementing an "Enterprise Resource Planning" (ERP) system, which may include software for banking and insurance transactions, permissible (halal), or is it preferable to try and change it?

There is no harm in working at the factory as long as its activity is permissible, even if it deals with usurious banks or insures its assets. However, it is forbidden to supervise a program that facilitates the factory's dealings with a usurious bank, due to the assistance it provides in committing what is forbidden, based on the Almighty's saying: "And do not cooperate in sin and aggression."
