Genius is looking for a Senior Full Stack Engineer—based in NYC or U.S. Remote—to help build the ultimate music companion, enabling fans to collaboratively transcribe lyrics and write annotations that live on Genius.com and everywhere people experience music. We’re looking for makers with a sophisticated code sense: folks who’ve built cool things, but who can also maintain and scale those things, and who feel at home deep in the guts of a library.

The best candidates will have professional experience on a web stack serving millions of users, will be proficient with Ruby on Rails, Postgres or MySQL, and have some experience with a front-end JavaScript framework (Angular, React, Ember, etc).

Genius is the world's biggest encyclopedia of music. Powered by its community, in-house creative team, and the artists themselves, Genius serves music knowledge to over 100 million people each month on Genius.com and everywhere music fans connect—including over 130 million users on Spotify and Apple Music—across the internet.

Founded in 2009, Genius began as a platform for annotating rap lyrics. Over the years, it has expanded its mission to include more than hip-hop, and more than just lyrics. Every song has a story that needs to be told, and the biggest names in music—including Frank Ocean, Lorde, and Cardi B—come to Genius to give the world insight into their art.
