One of the hardest things to figure out is when to ask for a raise. While it never hurts to have some data on the national averages for particular job titles, there are are a lot of individual factors that go into a person's particular salary.

Job-hunting site Glassdoor has tried to do help people with that with a tool it calls "Know Your Worth." It sifts through its database of millions of self-reported salaries from hundreds of thousands of companies and calculates things like job titles, years of experience, and cities to come up with a suggested salary for you.

Glassdoor recently took this analysis to the next step and looked at demand and salary trends for particular jobs. As demand goes up, it gets harder to hire people and salaries go up. Glassdoor calls the statistic that factors in demand and salary trends "market value."

It then looked to see which jobs titles had the most people who were not getting in on the higher wages.

In other words, it came up with this list of tech jobs where you could be selling yourself short if you don't negotiate for a raise. And the surprise of this list: Some of them are actually already high-paying jobs.
