What is the ruling on working for an agricultural company whose owners deal with Jewish experts, and which sells products that may be used in the manufacture of intoxicants, while being forced to pay bribes to facilitate the work?

There is no objection to working for the company unless its dealings are with experts who harm Muslims, or it sells its products to those who use them in the production of alcohol, and your work involves assisting in that. It is impermissible to pay a bribe to establish falsehood or invalidate truth. However, if paying it is the only way to obtain a right that cannot be acquired otherwise, then there is no objection, and the sin is on the taker, not the giver.
