Hiring

Infosys will hire approximately 200 workers in Georgia's Cobb County, approximately 30 miles north of Atlanta. The IT services company says it relies heavily on local universities and technical colleges to recruit workers. The hiring is part of a planned expansion in the area over the next several years. The effort will further drive the trend toward increased IT hiring in the Peach State, which has also seen salaries edge up since the recession. Riverbed Technology plans to hire about 250 in technology this year, with most positions going to developers, tech support and QA staffers. Some positions will include software engineers who can develop automation tools to deploy the company’s Stingray products. Other needed skills include C/C++ programming in a Linux environment, file systems and networking. Teradata is hiring approximately 200 engineers and technical consultants. The Ohio-based company has some 100 engineering positions open in software, testing, hardware and architecture. A similar number of consulting jobs are available.

Laying Off

Peripherals maker Logitech International is cutting 5 percent of its worldwide non-direct labor force, or 140 positions. Among the areas likely to be spared is the mobility products workforce, given the company's increased focus in that sector. Zynga will trim about 30 people, or 1 percent of its workforce, as it consolidates offices. Its teams in Austin and MicKinney, Texas, will relocate to facilities in Dallas and North Austin, while its Baltimore studio will close. The company is also considering whether to merge its New York City general office and mobile studio. In a blog post, COO David Ko said Zynga was able to relocate everyone from the Baltimore office who wanted to do so. Compuware began laying off 160 people, or less than 5 percent of its workforce, according to an SEC filing. The cuts will be across all of its operating and administrative divisions. Orbitz will reportedly lay off about 70 people, or 4 percent of its employees, the Chicago Tribune reports. The move is meant to improve efficiency, the company said. Electronics retailing giant Best Buy will let 400 jobs go at its Minnesota headquarters. It said the cuts are being driven by the ending of some "non-core" activities, the elimination of management layers, and general "efficiency improvements." Hemlock Semiconductor is permanently eliminating 400 jobs, 100 in Michigan and 300 in Tennessee, according to MNews.com. Is there hiring or firing going on at your company?
