Red Hat (NYSE: RHT) is mulling the relocation of its engineering headquarters in Massachusetts to California and is preparing to add up to 180 new jobs. According to Westford Eagle newspaper, the city has offered tax incentives in an attempt to convince Red Hat to expand the operation there. Angus Jennings, the town's director of Land Use Management, told the newspaper in an interview published Nov. 12 that Red Hat is looking at Mountain View and Sunnyvale, Calif. as possible locations for the headquarters. Through two recent acquisitions, Red Hat has a growing presence in the Silicon Valley area. According to Jennings, Red Hat is looking to add 180 new jobs with 100 to be created over the next two years. Red Hat recently decided to keep its corporate headquarters in Raleigh, adding jobs and taking space in a building now occupied by Progress Energy in the city's downtown.
