General Motors is hiring 1,000 employees to staff an information technology innovation centre in a Phoenix suburb, joining Austin, Texas; Roswell, Georgia, and Warren, Michigan, as part of a strategy to bring high-value IT work in house.

GM expects to hire over 4,000 new IT workers over the next three to five years to staff the four centres. So far, over 1,000 employees have been hired for the three locations previously announced.

GM chose the locations by looking at IT talent-rich areas that also offer a strong community, lower cost of living and a high-tech industry presence.

"Operating four IT Innovation centres geographically dispersed across the US allows us to offer employment opportunities to hundreds of thousands of IT professionals, over 75% located within a 500 mile radius of any one of the centres," the automaker said.

Combined, the four centres have access to more than 7,000 students at more than 150 colleges and universities majoring in information technology related fields. GM will target recruitment efforts at up to a dozen key universities within each of the four geographic regions.

On 1 April, GM will open a temporary centre and begin hiring in Phoenix until its permanent building in Chandler is completed.

It is expected to be operational by first quarter 2014.
