You're not really an engineer. You won't be signing any design plans certifying their safety, and you won't be liable when it's proven that they aren't safe.
I assume SoftTalker is referring to SWEs not being Professional Engineers.
Professional Engineer (PE) != Engineer (in many jurisdictions)
> A professional engineer is competent by virtue of his/her fundamental education and training to apply the scientific method and outlook to the analysis and solution of engineering problems.
> He/she is able to assume _personal responsibility_ for the development and application of engineering science and knowledge, notably in research, design, construction, manufacturing, superintending, managing, and in the education of the engineer.
