Genius is looking for an iOS Engineer to architect and implement new features on iOS. 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 an iOS app serving a large volume of users, will be proficient with Objective C and Swift, and have some experience with the core technologies we use (Auto Layout, AVKit, and Realm).

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 and everywhere music fans connect 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.
