Most states have some protection around advertising yourself as a "Professional Engineer" (PE) or similar term that implies you are licensed by the state to provide engineering services to the public. Only a few states apply this sort of orthodoxy to the general term "engineer", and the enforcement tends to be pretty lax.
Check on LinkedIn, there are several million people listing themselves as some form of Engineer--while most of them have an engineering degree from an accredited university, the vast majority of them do not have any PE licensure, for the simple reason that in many engineering fields there's just no reason get a state license.
Intel is in Oregon--and they employ thousands of degreed engineers and they definitely aren't PEs. Those job postings are advertised as "engineers" and the employees use the term "engineer" on their business cards and LinkedIn profiles.
