In the US you have Professional Engineers (PE). Though there's no longer an exam for software because so few people got it. It's mostly for people who have to sign off on things for regulators. I took the engineer-in-training exam early on (I'd have eventually wanted a PE in my first job) but I had career shifts and there was never a reason for me to pursue it further and I'd probably have had to retake my E-i-T in a different state anyway.

However, in general, there aren't restrictions on calling yourself an engineer and all sorts of basically technician roles use the term liberally.
