This is they way it is an many states, including mine. The way around it is usually just to not claim that you are providing engineering services, but rather that you are providing technical services. I've been doing that for 35 years. Here, to testify as an expert witness about engineering matters, you need to be a licensed professional engineer. I don't know if you can play the same "technical" vs "engineer" game there, but I suspect you can provided you don't claim to be an engineer. You can say that you have an engineering degree all day, that's a statement of fact. But, in that context, being an "engineer" is a matter of legal definition in the state.

 

The case in Oregon was talked about here for a bit.

The engineering manager at work was a PE, so he could sign off seismic and construction details for semi tool installs.

 

In Georgia, Alabama, and Tennessee a Licensed Professional Engineer's (or Architect, Civil Engineer) Stamp is required on all drawings for Public Works. I worked on several construction project structural designs and drawings at our plant but since it was not a "Public Works" the engineering stamp was not required. Nor was it required for the house architectural plans that I made for my home construction permit. Not quite sure as to Consulting or Testifying requirements. I know that stamps were also required by "outside" Engineering Firms for structural construction designs but not for operating machinery. In Georgia we also require a Licensed Surveyors stamp on Survey Plats. A stamp being an embossed stamps imprint on the prints paper much like a Notary Public's stamp imprint.
