About us

Zenly started in 2011 as a small team of passionate designers, engineers, and entrepreneurs gathered around the idea that frictionless location sharing is the next mobile commodity. Our R&D has brought us to release the best location sharing app in the world ;)

And now, Zenly is the mobile application that lets you instantaneously see where your friends are. We believe that making maps more social and personalised is our opportunity to improve the way people live, communicate and share moments together. Our product empowers people to find themselves, enjoy improvised moments and have fun together.


Our Android app is 50% Java, 50% Kotlin as we develop new features using it and continue to migrate old Java classes to Kotlin. We have an extensive use of RxJava for communicating data flow from and to the UI through various threading mechanisms. As weird as it might sound, we also embed a custom library compiled from Go to help us handle complex heuristics that we can share between iOS and Android (maintained by a separated team even if you are welcome contributing to it).

Zenly is a very graphical app and as such, your work will be split between custom UI components, gestures, lots of animations and architectural challenges driven by the high level of communication between all different parts of the app.

You will work with passionated product and engineering people (mostly pure Android fanboys) to make Zenly one of the best Android app on the Play Store.

You will ensure a high standard of coding, following best practices and continuous integration processes. In your code, you will keep our core values in mind: usability, security and customer service.
