True but here in the US "engineer" is not the term that matters. "Professional Engineer" is the term given to licensed and accredited engineers - generally identified by the initials "p.e." after their name, and you usually include some indication of the state you are licensed in.
Since graduating with an engineering degree is not enough to become a "Professional Engineer" in the US, you can actually argue it makes some sense to differentiate the terms - being licensed as a PE requires 6 years of professional engineering experience before you can even take the exam. So simply listing a job title of "engineer" might help demonstrate relevant engineering experience but means nothing with respect to your actual license.
