Working for consulting company that also provides defense consulting


I have a question regarding the permissibility for a position i am interested. I am thinking to apply for a position in a top consulting firm however, i am puzzled on the permissibility of it in islam as they also provide consultancy work for the defense industry that produces weapons. I have no clue on the type of work that we are doing for them. is it okay to apply for the position ?

Jazakallah Khayr
