Clue is hiring a

Senior Android Developer

About Us:
Clue is the world’s fastest growing period tracking and fertility app. We are a 45-person, VC-­backed startup based in Berlin. Every month, millions of users track data about their bodies in Clue’s iOS and Android apps. With every data point, Clue users gain knowledge about their own health, impact the entire community of Clue users, and advance reproductive health care globally. Here’s some media coverage about us. We at Clue are committed to a culture of inclusivity and mutual respect.

The Role:

Clue for Android uses minSdkVersion 15, RxJava with Retrolambda, Android Studio with Gradle for builds, and RecyclerView all over the place. We embrace Material design. The app is filled with custom views and layouts. We’re excited about pushing the limits of the Android platform’s capabilities, and you should be too.

And you? You dream in Java… when you’re not dreaming in Kotlin. You’re obsessive about UI and UX, twitching when things are not buttery smooth or off by 1 pixel on an xxxhdpi screen. You love Samsung — and have a strong sense of irony.

You are able to work independently and own a project, but you also love to collaborate with your colleagues. And you care about user feedback and how your work touches people’s lives. Participation in the Android community is very welcome.

Please address your cover letter to Vanessa.
