As a non resident alien, the only time you are required to pay taxes or file a tax return in the US is if your income is physically made within the United States. Even though you are employed and paid by a US company, since you do not live or work in the US and you are not a US citizen, then you are not liable for taxes on this money.
You also do not need to report the existence of the bank account. Even if the bank account earns interest, as a non resident alien this is non taxable income to you.
I am giving you a link below to a chart that shows the various types of income which are taxable to a non resident alien.
