What is the legal ruling on working for a company that implements information technology programs for the Egyptian Ministry of Finance, which manages the Ministry's payments (such as salaries and pensions) and collections (such as customs, taxes, and insurance) that are deposited in government banks until they are disbursed?

There is no impediment to working for the aforementioned company and developing such programs, as their fundamental use is Islamically permissible. If the Ministry of Finance uses them in an impermissible way, this does not preclude working for the company, as the ruling is based on the predominant use, and the questioner's work is unrelated to the Ministry's practice of placing its funds in banks and earning interest on them.
