Bill Flook writes AWS used $500,000 in funding assistance from Gov. Bob McDonnell for the expansion, which is intended to help create 500 new jobs.
The company held a grand opening ceremony Monday that was attended by state and local officials, including Virginia Secretary of Commerce and Trade Jim Cheng and U.S. Rep. Gerry Connolly, according to the report.
Stephen Schmidt, chief information security officer at AWS, told the Business Journal the office is hiring systems and security engineers and software developers, among other positions.
Last month, Amazon said it would invest $9.5 million in the Fairfax County facility, Flook reports.
