What's in a name? A lot if you are in some of the high-growth sectors of the U.S. labor force.

Companies are adding C-level jobs designed to oversee and maintain growth as the economy improves and firms realize they cannot simply cost cut their way to prosperity, said Robert Damon, executive chairman of Americas at Korn Ferry International.

Some of the hottest new titles that the executive recruitment firm has identified include chief revenue officer, chief digital officer, chief sustainability officer, and chief innovative officer.

With companies facing pressure to maintain revenue growth, the trend amounts to more than just title inflation, Damon told CNBC's "Squawk Box" on Friday.

"The increased importance that companies are putting on these functional areas is a reflection of the titles," he said.

Among Korn Ferry's top 15 sectors for executive positions are health care, new media and social media, cybersecurity and risk management, and energy.

"The whole social media area is a very hot area. And if we think it's hot today with social media 1.0, social media 2.0—when companies start to take control of their own social networks—is going to really disrupt the business situation substantially," he said.
