Employment momentum in the US tech sector experienced a modest bounce-back in September, according to CompTIA’s analysis of the US Bureau of Labor Statistics’ monthly employment situation report, released Friday. The nonprofit IT industry association found the tech sector in September added an estimated 5,900 jobs.

The IT services, custom software development and computer system design category led employment growth with a gain of 4,800 jobs, followed by computer and electronic products manufacturing — which added 2,100 jobs — and data processing, hosting and related services, up by 1,600 jobs.

CompTIA also noted the number of employer job postings in September fell by an estimated 2,700 from the previous month. Software positions were the most in demand, followed by IT support specialists and systems engineers. Cybersecurity positions and jobs related to emerging technologies also continue to show strength.

“Between the very low unemployment rate for IT occupations, the transitions underway to newer technologies and external economic or policy factors, it’s not surprising to see mixed signals in the employment data,” said Tim Herbert, senior VP for research and market intelligence at CompTIA.
