(Fatwa: 435=427/B)
The insurance companies deal in interest and you will draw your salary from the same money. Therefore, this earning is not pure and it is better for you to avoid it.
And, if your work involves designing of pictures (of living beings) and writing interest accounts, then this employment and the earning will be Haram. Therefore, it is advised not to work in the insurance company, according to the Hadith: دع ما یریبک الی ما لا یریبک
