What is the ruling on working—throughout the training period and after employment—on a massive software project directed at a government to manage social security laws, solidarity, and social insurance, knowing that it is not directed at a specific for-profit insurance company?

There is no objection to working for companies that develop general software programs, which can be used for permissible and other purposes, as long as the programs are not sold to a party known to use them for impermissible purposes (such as usurious banks and wineries), or if the work is not directly related to selling the program to a party that uses it for impermissible purposes. It is permissible to work for mixed-activity companies as long as their primary activity is permissible, while observing the following guidelines: The company's primary activity must not be impermissible, the product must not be specifically designated for an impermissible matter or predominantly used for it, and the employee must not directly engage in the impermissible work himself.
