Backend Developer
MuseHub is where millions of creators get their music tools: Muse Sounds, plugins, sample libraries and apps like MuseScore and Audacity, all in one desktop app and web storefront. We relaunched it this fall with ambitious goals, and now we’re looking for someone to own its backend.
Today MuseHub runs on its own Azure and .NET stack. Your mission is to move it onto the shared Muse platform (modern PHP), make it much faster, and then take full ownership of it. You’ll be the go-to backend engineer on a product team that ships fast.
We are actively integrating AI automation into relevant areas of the business and expect candidates with mindset focused on improving efficiency and deliver a better user experience.
