I just looked this up so might not be fully accurate but it seems most private sector “engineers” don’t require a license. You only need a PE license when providing a service to the public. That is quite a strict band on the title.
Might also be different between countries. But a bridge wouldn't be built without an engineer signing off on it being safe. A process change at a production facility would need an engineer to approve that the output still will follow specs etc
