There are a series of licensing exams for the (non-software) engineering fields: one typically takes the Engineer-In-Training exam at the end of undergrad, then can take the Professional Engineer exam after a few years of working under a licensed PE (exact regulations vary from state to state). These exams are more common for civil than electrical engineers; if I remember correctly, there are regulations that require a Professional Engineer to sign off on blueprints.
