There are a number of advantages to hiring Scheme developers. First, Scheme is a very concise and elegant language which makes code easy to read and maintain. Second, Scheme has excellent support for metaprogramming, meaning that code can be written in such a way that it is easy to change or extend later on. This can be extremely useful when working on large or complex projects. Finally, Scheme developers tend to be very well-educated and experienced in programming languages and software development in general, making them valuable assets to any team.
