Urgent help needed about a developer role for a lending protocol

So I’m blockchain developer and have recently got selected for a developer role at a zero-Collateralized lending protocol which is more like AAVE except its not under-Collateralized and have been waiting to get such a developer role for a while now.
Zero-Collateralized: We can borrow same amount of tokens as we have depositted but using blockchain and ethereum
So is that straight haram or is it permissible for me to work for them as their developer?
