Though more IT and engineering jobs are being created in the US, the latest job numbers show the pace has been falling off, according to the TechServe Alliance, the trade association of the IT and engineering staffing and solutions industry.

“For the past three months, the rate of IT jobs growth has been sluggish,” CEO Mark Roberts said in a statement. “While it still represents an increase in IT employment, the rate of growth has generally been on a downward trajectory for the past year. Similarly the rate of engineering job growth decelerated after posting stronger June numbers.”

The number of IT jobs rose 0.1% in July to a total of 5.3 million, according to the TechServe Alliance. Comparing July to the same month last year, the number of jobs was up 2.9%.

Engineering jobs also grew by only 0.1% month-over-month.

“Given the extremely low unemployment rates in many high-demand IT and engineering skill sets, the shortage of supply is clearly impeding the growth rate of the US technical workforce,” Roberts said. “More restrictive immigration policies being proposed by some policymakers would only further exacerbate this trend.”
