The company I work for has openings right now, but you must be willing to travel and live near an airport. Good understanding of networks, and Window's OS is needed. Basically we install a client server app at a customer location, test the app, train the customer in it's use, then leave.
Some things that would also work in an applicants favor would be a good knowledge of SQL. In our near future we'll be working with Microsoft Expressions, Silverlight, Windows Presentation Foundation, XAML, etc., anyone with a good knowledge of these products would have a definite leg up.
It's a great job if you don't mind about 50% travel, sometimes we go out to a customer site, but there are also installs we do remotely (you work at home).
