MUMPS, or simply M, stands for Massachusetts General Hospital Utility Multi-Programming System. Essentially, MUMPS is a database with a language of its own that is one of the oldest hospital database and language systems in the world. As a MUMPS developer, you use the MUMPS language and database to create software to support projects for various healthcare and clinical systems, financial institutions, and even space agencies. Your duties and responsibilities as a MUMPS developer vary based on what you are doing with the system, but generally speaking, you are creating new technologies using the MUMPS system as a base.
