What is the ruling on working in the sale of ice cream that contains alcohol, especially with the scarcity of job opportunities?

If the alcohol added to ice cream remains intoxicating, then it is not permissible to use it, sell it, or work with it. However, if the alcohol has been processed and is no longer intoxicating, then it is permissible to use it, sell it, and work with it; because if an impure substance transforms into a pure substance, the ruling of impurity is removed. If you were unaware of the presence of alcohol, and a trustworthy employer informed you that it was not present or that it had become pure after processing, then there is no harm in working with him.
