Of the list, columnist Julie Bort writes, "you are going to be surprised, because it's not all about the latest, greatest new thing. Sometimes an older technology is still in demand, with companies competing heavily for people who can still do the task."
So who knows? Maybe you already have one of these in-demand skills, and just need to brush up your resume. Here are three of the ones that surprised us the most:
1. PowerBuilder - $102,000 and up.
This software development tool is mostly known for developing 1990s-era .Net apps that work with databases by Microsoft, Oracle, and Sybase. Because most developers study competing technologies, .Net developers are harder to find and therefore in greater demand.
2. Silverlight - $103,000 and up.
"If you don't already have Silverlight skills, don't kill yourself to get them," Bort writes. "Although Microsoft won't formally admit it, Silverlight's lifespan is limited."
Still, there are plenty of companies with rich media apps based on this technology who need developers, and fewer folks who have this skill. Might as well cash in now while you plan your next move.
3. Erlang - $107,000 and up.
This computer programming language is so old, Business Insider illustrates its entry with a sepia-toned photograph of the mathematician who inspired it. Erlang was released as an open-source language in 1998, and has gained popularity recently because of cloud computing.
