Kye Mitchell, head of Experis North America — a ManpowerGroup tech recruiting business — said demand increased among tech employers in December, particularly related to the “gig economy.” Uber led the surge in such jobs with a remarkable 4,150% increase in job postings, while Outlier Inc., a platform that connects experts to advance generative AI, saw a 342% rise in demand.

“This trend was also evident in the temp job market, where the demand for computer and information research scientists skyrocketed by 2,000% as organizations focused on developing artificial intelligence and machine learning, increasingly relying on temp workers,” Mitchell said.

In December, there were 434,415 active tech job postings, including 165,189 newly added (both down from November). Roles in software development, IT project management, cybersecurity, data science, and tech support saw the most activity, according to CompTIA.
