I'm not an engineer or a lawyer. ;-)

Nobody's skirting the law. In most US states, there is a so called "industrial exemption," which allows you to do engineering without a license if you work for certain kinds of employers. I work for such a company, though I don't have an engineering title. But when we do offer a product for sale to the public, it goes to a third party for approval, and the people at that company who conduct the design review all have engineering licenses. The thing that will get you in trouble is offering engineering services directly to the public.

Now in my state, there are only licenses for a small handful of engineering disciplines: Electrical, mechanical, power, etc. I don't know if it means that the rest of us can't call ourselves engineers at all, or if we're just unregulated. I've never tested those waters.

From what I've observed, people with engineering job titles rarely do any hard quantitative engineering. Most of the work consists of organizing and arranging things, fitting things together, troubleshooting, etc.
