Symantec has over 21,000 employees dedicated to creating top-of-the-line cyber-security software. Though employees are expected to know a number of computer-programming languages — Java being the most popular — PayScale found that the best-paying skill is Python. The best-paying position? That would be principal software engineer, which draws a salary of $140,000 on average.
