Makes sense, I've always been of the opinion that it's my responsibility to improve upon my skills and that most business-oriented softwares are not going to be challenging. But I think you're right, it will be much more fun to work on a challenging project at my job.

I do want to become a better engineer, so I'll just do that for now. I'll look for a better company, as one other comment suggested. To find a company that makes developer tools, like IDEs, compilers etc.
