I'm going to work in a new Islamic bank what is your opinion about that?

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

There is no objection in working in an Islamic bank - Allah Willing - that acts in its business according to the regulations of Sharia.
As long as there is a body of Islamic specialists in this bank that supervise the operations of this bank, working there is permissible.
Allah knows best.
