I see one engineering job ad https://careers.epicompany.eu/jobs/6909459-senior-full-stack... if we can call EU Digital Wallet speculation "engineering".

But you just answered your own question.

Wero is a money extraction business that secured European Commission support. There is no engineering nor payment system to it.

what ever "money extraction business" means - wero is a real thing people (me included) are already using and developed jointly by many european banks.
