America Online is significantly reducing its software development operations in the US by closing its offices in San Francisco and San Diego and cutting 375 positions at its Mountain View campus.
A total of 450 California positions will be cut as part of the company's efforts to manage costs, said AOL spokesman Jim Whitney.
About 100 of the employees will be offered the opportunity to relocate to AOL's Virginia facilities.
"These are principally developers who work on features and applications for the AOL service, " Whitney said. "What we're doing is actually moving some of our projects into teams in other facilities."
AOL will continue to maintain California offices in Irvine, which will have a staff of 75, and Mountain View, which will now house 300 employees.
In July, AOL laid off 50 Mountain View-based developers of its Netscape browser. The company's Mountain View campus was formerly the headquarters of Netscape Communications, which AOL acquired in 1998.
