The first thing you need to do is to go to graduate school for engineering.

Basically, if you want to do a good job in engineering, that is to say, if you want to take the scientific research route, then graduate school is the minimum, and many tutors require a doctoral degree.

Bachelor's degree in science is just a scratch, and a lot of it is obsolete technology

If you want to go as an engineer, a master's degree is basically enough to satisfy your work needs

If you just go to the market, or if you go to the sales of an engineering background, you don't need to go to graduate school

If you want to go to the market, you don't need to go to graduate school at all.
