29 companies adding jobs in Fairfax County

Twenty-nine businesses announced plans to add more than 600 jobs in Fairfax County during the third quarter of 2013.

Most of the businesses expanding or relocating in the county are in the information technology and professional services sectors. Seven are foreign-based firms using Fairfax as a site for expansion in North America.

“Fairfax County’s strengths in IT and professional services continue to be a draw for companies from the United States and around the world to locate and expand here, and that creates more jobs that strengthen and diversify our economic base and support the quality of life we enjoy here,” Gerald L. Gordon, president and CEO of the Fairfax County Economic Development Authority, said in a statement.

Gordon said that while the quarterly numbers are lower than historical trends for Fairfax , they are indicators of the county’s underlying economic strength.

The biggest job gain came from Appian, which develops business process software. It is adding 90 jobs.
Other companies adding more than 50 jobs include the Internet research firm comScore, 75 jobs, and Delex Systems, an IT, program management and research firm, 61 jobs
