Is it permissible to work as a senior IT technician in a secular court that does not rule by Islamic Sharia?

Actions that facilitate the work of courts ruling with man-made laws contrary to Sharia are not permissible, due to the assistance they provide in wrongdoing. Allah Almighty says: "And do not cooperate in sin and aggression." Abandoning a forbidden act seeking Allah's pleasure will be compensated by Allah with something better, as the Prophet (peace be upon him) said: "Indeed, you will not abandon anything for the sake of Allah Almighty except that Allah will give you something better than it."
