What does irk me is that in real life, software developers who meet the Etsy CTO's standard often can't call themselves engineers. In many countries, misrepresenting oneself as an engineer without accreditation is against the law! [1]
In the U.S., there's no official occupational category for Software Engineer. It's just Software Developer (Applications), Software Developer (Systems), and Computer Programmer.
It is possible to get accreditation (http://ncees.org/exams/pe-exam/, under Software), but it didn't appear very useful to me aside from being able to call yourself an Engineer.
