🏢 Zenly 🇫🇷 Paris, France 🕑 March 29

This job offer is expired

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.

We’re looking for an Android Mobile Engineer to join us at Zenly! Working from our Paris, France headquarters, you’ll play a key role in building and shaping key features that millions of Zenlyers will use every day!

Our office is big and comfortable with a fully equipped kitchen (including unlimited snacks and drinks), rest areas and sound isolation booths. Everyone at Zenly is provided with a spacious desk and top of the line computer and phone to help you build your own workspace.

We also offer a great package to all our employees including:

Advantageous health coverage extendable to your family

Public transport reimbursement

Weekly lunch (and regular french pastry for breakfast!)

Flexible time off policy

Handling of relocation/visa procedure


As an Android Mobile developer, you will be responsible for architecting, developing, maintaining and releasing features as well as contributing to the core foundations of the Zenly mobile app.

Our Android app is mostly made of Java but includes more and more Kotlin as we develop new features using it. 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 a passionate product and engineering team to make Zenly one of the best Android apps on the App 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.


  • Experience building a mobile app from scratch to the Play Store
  • Excellent knowledge of the Android SDK (View architecture, Components, Theming, etc..)
  • Experience with multi-threading, memory management specific to mobile devices and caching mechanisms
  • Experience with software engineering best practices (testing, code reviews, continuous integration, design documentation…)
  • Self-organized and proactive with the ability to prioritize tasks effectively


  • Experience in Kotlin and RxJav
  • Experience in embedded systems
  • Experience with 3D graphics libraries or 3D engines
