In the US, to become a licensed engineer you need to get an accredited bachelor's degree in it, and then pass the "Fundamentals of Engineering" exam to become a state-licensed "Engineer in Training (EIT)," and then work in the field for four years, and then pass the "Principles and Practice of Engineering" exam to become a state-licensed "Professional Engineer (PE)." The degree is just the first step.

Does Australia let civil engineers certify construction plans straight out of college? (Answer: apparently -- and surprisingly -- some states do!)

Fwiw in my previous comment's second paragraph when I said "practising as an engineer" that meant "practising as a [software] engineer". I wasn't claiming that that's how it works for all fields of engineering, but pointing out specifically how software engineering is more similar to degrees in computer science, IT, or being self taught.
