Senior Full Stack Engineer

Job description

Primephonic is a fast-growing music streaming service that has been dubbed by the media as ‘the Spotify of classical music’. By building an app dedicated entirely to classical music, we reinvent the digital classical music experience and reignite a global passion for the genre. Classical music lovers are currently heavily undeserved in the digital space, which is why it’s our mission to build a better future for the genre by offering the world’s most extensive classical music catalogue, available to stream in the highest audio quality with world-leading search functionality built bespoke for classical music. Our app is underpinned by a payout model which sees classical musicians paid in a fairer way than traditional services. Primephonic launched its streaming service (iOS, Android and web) in the United States, United Kingdom and The Netherlands in September 2018. Since August 2019, Primephonic is available in over 150 countries. With offices in New York City and Amsterdam, our rapidly growing team is home to 30+ classical music lovers of twenty different nationalities. Primephonic has been covered by a.o. The New York Times, the LA Times and the Financial Times.

Our platform is made up of several different systems. From robust APIs powering our apps, to music label reporting, to complex musical metadata matching, to high-throughput streaming services, which are all crucial to our business. We can’t wait to show you the tech powering it all!
