Don't forget Benefit Focus. They have office in Greenville and Charleston (HQ), have been growing like crazy and went public a couple years back. That company is doing really well and can't seem to hire people fast enough.
Benefit Focus from everyone I've known who has worked there pre-public said the company is absolutely terrible to work for from the engineering department perspective.
I worked there for two years. Loved the people there, but the engineering definitely wasn't great. Imagine a Java application that started in 2000 and hasn't really had any significant rewrites and is now too big to change. They run a good business and offer a lot of value to companies who use their product, but the engineering was definitely tough in the not-so-fun way due to the sheer amount of legacy code.
