What is the ruling on a transaction that involves selling a gold factory to a first merchant without taking possession or paying the price, then the factory selling the gold in the market, and the first merchant then selling part of the gold back to the factory and another part to a second merchant, and what is the ruling on working in this factory?

It is not permissible to sell unmanufactured or raw gold for cash on credit, nor is it permissible to sell manufactured gold in this manner, according to the majority of jurists. This is because the characteristic of being a medium of exchange (price) is present in both. Selling gold for cash on credit is prohibited when the types differ and immediate possession is not taken.

If both exchanged items involve deferment (selling on deferred payment with a deferred price), the transaction becomes prohibited. This is due to the scholarly consensus on the impermissibility of selling a debt for a debt.

Regarding the questioner's work as an accountant in this factory, if the factory deals exclusively through this prohibited method, then working there is not permissible, as it constitutes aiding in sin. However, if the factory mixes what is permissible with what is prohibited, then he can work there, provided he is able to avoid the prohibited transactions.
