What is the ruling on working to obtain banking facilities for companies while not being at ease with the fatwa permitting it, and does this affect one's job and the risk of losing it?

Banking facilities cannot be judged in absolute terms. Some are permissible and without objection, such as letters of guarantee, documentary credits, and Murabaha sales. Others are forbidden, like usury (riba) and transactions that the bank uses as a legal trick (hila). To ascertain the permissibility of a transaction, one can refer to the Sharia boards in Islamic banks.
