IT for Bank...

My question is about whether it is permissible to work for a financial institution's IT (Information Technology) department. I work as a team to support the systems that run financial applications similar to a bank although the company I work for is not a bank. Transactions do involve interest. I personally do not have to write/print any documents regarding the transaction and never have to deal with the customer. In other words, the transaction is completely invisible to me. My responsibility is to keep the systems up and running.

Answer
In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatuh

If your employment involves working with any systems which are directly related to anything impermissible then this employment will also be impermissible. For example, a persons employment is to maintain interest calculating programmes, then this will not be permissible (makrooh tahreemi).(Sabab Qareeb Ghayr Mutaharrik)
