I covered that Google To Set Up Offices In Michigan yesterday. Basically one-thousand Google employees will be housed there, primarily as a "call center." It appears that this will be a call center for AdWords support. It is also of importance to note that the two Google founders graduated from University of Michigan undergrad.
You can see the local coverage of this news at FreeP.com. The article shows that the "average salary for new hires is expected to be $47,000 a year." You will see that the Michigan - Ann Arbor job openings at Google include two for Operations and IT and three for Online Operations, expect 995 more. :)
