As the largest social network for language learning in the world, we’ve already had some great success, but there is so much more that we want to build and improve on. We’re looking for smart, agile, independent engineers who can help us take our Android apps to the next level, providing more amazing ways for our users to interact with one another and further improve their learning. You'll be someone who loves the user experience, can build beautiful and efficient apps and isn’t afraid to share opinions on the best way to design the APIs they’ll be consuming.

Our project is based on an MVP architecture. Working in an Agile team (Scrum), we like to brainstorm during pair programming and seeing green bars using TDD. We make use of Dependency Injection and libraries such as Retrofit, JobQueue, Ormlite, EventBus and others. But we’re always open to change and the best tool for the job should be the one we’re using.

The Android platform is the fastest growing mobile platform in the world, especially in the emerging markets that we count among our biggest countries. Android at busuu is growing faster than ever, leading the switch to mobile in greater and greater numbers. We’re live in more than 40 countries across the world and we want to keep adding to that and to the features that we’re bringing to our millions of users. The reach and impact that our Android app has across the world, is to enrich users lives through easy access to language learning, meaning it is incredibly important to us to continue to build extraordinary Android applications that are accessible to everyone.

As an Android Engineer you’ll be working on our flagship and region-specific apps, shipping to over 40 countries throughout the world in over 10 languages, offering our users a huge variety of languages to learn from. You’ll think about how users interact with our learning experience, how to help them learn better and faster and then build an experience that everyone can enjoy learning with.

You’ll work on brand new and existing features, often shipping and supporting your application all the way to production and beyond. You’ll work with an amazing, experienced team of Android engineers, and think about the entire lifecycle of the application - from architecture to automated testing. We’re not afraid to do the right thing, refactoring when necessary while at the same time ensuring that we’re shipping new features to consumers as fast as possible.
