By definition I am a Reliability, Maintainability, Systems Safety Engineer and that is what I am classified as in all of the firms that I have worked for. Granted I do not have an engineering degree as I majored in Industrial Design but my resume (CV) shows all of my experience and that experience is defined by the work that I do and that is RMS Engineering or Product Integrity.
Regarding My A&P license If I remember correctly I got my P license in the 1960s and I got my A license in 1976 and my ticket is still valid with the FAA.
