The short answer is get a college or university degree in electrical engineering.
However, the broader question is... what does it take to be come a XYZ Engineer? It could be mechanical engineer, civil engineer, electronics engineer, software engineer, cybersecurity engineer, etc.
First and foremost, all supervisors are looking for employees who possess problem solving skills. You are hired to solve a problem; build a new website, develop a new application, manufacture a computer chip. We often time emphasis a single answer to a giving problem. In reality, there are multiple acceptable answers depends on how you phrase the problem. We can even change the parameter of the problem if you don't like the answer.
Second, technical knowledge. You cannot perform the function of electrical engineer if you do not understand Calculus or electromagnetisms. There is no short cut of study math, physics, and chemistry if you want to be an electrical engineer (or any other engineering).
I still remember the reasons why I chose an electrical engineering degree from UCLA 25+ years ago. I was fortunate that after college I started my career as a Systems Engineer. I did not need to solve differential equation in my work area. However, the Shannon's Information Theory that I learned in UCLA helped me understand how wireless phone works and I remained in the wireless industry for the past 20+ years.
