Legal Question in Employment Law in California

Yes and no. An unlicensed engineer can teach, if the have the knowledge and skills, just as a highly experienced paralegal can teach legal topics. My ex-wife was such a highly regarded trademark paralegal that she taught seminars on trademarks to the US Patent and Trademark Assn.convention, for example. You can also do engineering work for an engineering firm without an license, just as a paralegal can do legal work under the supervision of a licensed attorney. The unlicensed engineer must, however, be supervised by a licensed engineer and they cannot sign or stamp drawings, calculations, specifications, etc.
