Is the work considered permissible or impermissible if the engineer works in a software company that deals with an intermediary insurance company, which in turn deals with cooperative and commercial insurance companies?

It has been previously clarified that commercial insurance is forbidden (haram). Accordingly, if your work at the company involves commercial insurance or assists in it, then it is forbidden and you must leave it, unless there is a compelling necessity, while diligently searching for permissible work. However, if your work is not related to commercial insurance or other forbidden transactions, then there is no harm in it for you, and you are not affected by the company's involvement in forbidden insurance.
