Picnic is an app-only supermarket. Our customers expect a mobile store that is smooth and bug-free. We’re on a quest for innovative Mobile Developers to push creative features while retaining simplicity.

Android Developer

🏦 Where you fit in 

Picnic’s customers rely on the mobile app. They use it to buy their fresh, high quality, and weekly groceries. Our developers make their interaction quick and seamless - not a finger marathon!

As an Android Developer at Picnic you’ll be working with Kotlin. We saw its potential in 2016 and embraced it. This reflects our mindset - pushing design to be simple and functional with a relentless focus on innovation. Check out our stats:

  • 4.41 star rating 💪
  • 99.5% crash free sessions 💯

Not bad. But you can help us do better.

You are accountable for maintaining an easy-to-use, reliable app. When updates are released, you roll them out to users and track their activity for bugs. A smooth app is vital. Critical bugs lead to; no deliveries, empty cupboards, and unhappy customers.

Using hands-on experience with the product development cycle you constantly test, evolve, and evaluate our features. You collaborate with designers to bring their prototypes into a functional reality. Real customers test the app in our user-testing lab giving you the opportunity to trial new features each week.

You’re ready to meet ambiguous requirements to ensure a smooth, elegant and user-friendly experience for all our customers!
