Non-software companies hiring a "hacker" who is cheap and can either write firmware and make firmware talk to hardware. These types of companies don't really have things like code reviews and teams of engineers. I used to work on embedded systems. The entire software team in the company consisted of myself and one other software developer. The only code review at that time consisted of "can you take a look at this funny bug that is occuring?" I suspect the entire system was developed by Charlie. I've been that Charlie person. We all make mistakes, and we all need to "just get it done." There is a difference between "harden something so it cannot be exploited" and "make it so the customer cannot take one of our devices and plug it in to a competitor's device."
