I asked the same question about 9 months ago. I got lots of replies, most stated the corporate world is hard to get into in Colorado because so many pilots want to get there/are happy there. I did do some research, but didn't get anywhere finding corporate positions. However, I did find plenty of Pt 135 jobs in the Denver area. The best (from what others have said and from my research) was Mountain Aviation at Jeffco Airport. They manage private aircraft and fly for the owners, but 80% of their flying is charter.
I'm originally from Nebraska but went to college in Colorado...Are you the same, about to move out to CU Buffalo Land?
