The main operating systems today are designed by software engineers working at various technology companies. You're probably familiar with Apple and Microsoft on home computers. Red Hat, Oracle, and IBM also produce operating systems used in various commercial and industrial settings. Apple, Microsoft, Google, RIM, and Symbian are the big OS developers on smart phones.
There is no requirement that operating systems be made by a team of software engineers at a big company or a university though. Anyone who knows how to make one is welcome to make them and there are a number of operating systems in development today maintained entirely by people doing it as a hobby.
