16. Computer Hacker
An ethical (or whitehat) computer hacker is someone who purposefully seeks to penetrate networks and systems in order to find weaknesses. This helps companies to find any weak areas in their system and prevent information from falling into the wrong hands. A computer hacker can make up to $100,000 a year depending on your skillsets and experience level. Most entry-level hackers have a bachelor’s degree in computer science. Whitehat hackers can find employment at private security firms, federal governments, or local authorities.
