Washington is one of those states where you can't call yourself an engineer unless you have a PE. If you are working independently. When I was employed by Intel my job title included the word "engineer" and that was fine. Never did work for someone with a PE, and if I did it would have been from a different state. And I know people at Intel with the word "engineer" in their job title who don't even have an engineering degree. Now that I'm retired from Intel my business card says "President". No regulations on that. "Consultant" would have been fine, too. Just can't call myself "Engineer" without that PE. Even though I have a BSEE from Washington State University. Heck, I even teach a seminar at WSU every year. Oh well...
Stupid, isn't it?
Lots of folks, with engineering degrees, merely use a different term in places of "engineer." They run consulting businesses with names like, "EMC Consultants" or "Electrical Design Services." They can even list their degree after their name, like John Doe, MSEE or whatever. So what it comes down to is the state boards are enforcing (rarely) who calls themselves "engineer" rather than who is practicing engineering.
Frankly, the field is so broad, that a clear
legal definition of "practicing engineering" is difficult. Many times, when an engineer runs afoul of the state board, he just backs down, but in cases where a qualified engineer decides to fight back the state often loses in court. Consequently, they seldom go after non-licensed folks who are truly engineers, unless the engineer is signing off drawings that require a PE stamp.
If you haven't read about the EE in Oregon, Matt Järlström, you should.
https://www.oregonlive.com/portland/index.ssf/2017/12/state_board_concedes_it_violat.html The board is losing:
Oregon's Board of Examiners for Engineering and Land Surveying unconstitutionally applied state law governing engineering practice to Mats Järlström when he exercised his free speech about traffic lights and described himself as an engineer since he was doing so "in a noncommercial'' setting and not soliciting professional business, the state Department of Justice has conceded.
"We have admitted to violating Mr. Järlström's rights,'' said Christina L. Beatty-Walters, senior assistant attorney general, in federal court Monday.
The state's regulation of Järlström under engineering practice law "was not narrowly tailored to any compelling state interests,'' she wrote in court papers.
And then we have the folks who use the title but have no engineering degree, no training, etc. Sales engineer, quality engineer, service engineer, audio engineer,
et cetera ad nauseum. Those I would like to see stopped.
Personally, I think the IEEE's position is reasonable:
It is our position that individuals who have graduated with an engineering degree from an ABET/EAC accredited program of engineering education should not be prohibited from using the title “Engineer.” The protected titles “Professional Engineer,” “Licensed Engineer,” “Registered Engineer,” and variations thereof should be reserved for those whose educationand experience qualify them to practice in a manner that protects public health, safety and welfare and who have been licensed to practice engineering by a jurisdiction.
