Berlin, Germany

The Opportunity

The SuperApp & Web squad sits within SumUp's Engagement Mission under the Run & Grow tribe. We are responsible for one of the most strategically important surfaces in SumUp’s product ecosystem: the merchant app home screen. Our mission is to make every SumUp merchant feel empowered, informed, and engaged each time they open the app. This involves owning the home screen, tools section, and profile & settings across iOS, Android, and Web platforms.

We aim to activate merchants early through a first-class onboarding experience, cross-sell and upsell products at the right moments via smart promotional components, surface insights for managing and growing businesses, and enable navigation to relevant app sections. The squad is cross-functional with iOS, Android, full-stack engineers, senior backend engineer, senior product manager, senior designer, and an engineering manager.

As an Android Engineer, you will be paired with a senior Android engineer who will support your onboarding and growth, allowing you to develop skills while contributing meaningfully from day one.

Your Responsibilities

• Build and maintain features of the Android SuperApp home screen, including first-time user experience, home screen widgets, quick actions, customization, tools section, profile & settings, and promotional channels with guidance from senior peers.
• Contribute to the Personas initiative by helping build a tailored and customizable home screen experience that reduces friction and surfaces relevant data for each merchant.

Skills & Qualifications

• A strong understanding of modern Android architecture principles such as MVVM (Model-View-ViewModel).
• Proficiency with Android Studio and the Android SDK.
• Knowledge of RESTful APIs and experience working with backend services.
