Android Engineer

At SumUp, we believe small merchants are the heartbeat of our communities. By joining the Payments BR tribe, you’ll help shape solutions that directly solve merchants’ everyday challenges and redefine how financial products empower entrepreneurship in Brazil.

As an Android Engineer, you'll be joining a growing squad at the centre of a highly cross functional environment: every change you make touches code, teams, and decisions owned across the wider SumUp organisation. You'll work side by side with engineers from other disciplines and tribes, take ownership of features from design to delivery, and contribute directly to technical decisions that shape how the Brazilian merchant experience connects to our global platform.

What you'll do

• Design merchant facing Pix flows: Build in-app experiences that help merchants clearly understand and manage their Pix transactions, automatic Pix, and Pix credit
• Work across the SuperApp ecosystem: Coordinate changes with other tribes, including Bank, Lending, Online Payments, and Platform, to deliver features that touch shared code and shared surfaces
• Contribute to technical decisions as an equal: Take part in architecture discussions and help the squad decide how to build and scale the Pix domain
• Write clean, tested Android code: Develop native features using Kotlin and Java, following modular architecture and solid testing practices
• Collaborate with the Mobile Chapter: Share knowledge, patterns, and lessons learned with other mobile engineers across SumUp
• Build cross-tribe relationships: Partner with senior engineers and stakeholders across tribes as you master the Pix domain and take on increasing ownership 

You'll be great for this role if…

• Track record of owning native Android features end to end, from design through to production
• Strong knowledge of modular architecture, MVVM, SOLID principles, and REST APIs
• Solid practice of unit testing and dependency injection
• Ability to navigate ambiguity and propose solutions independently, with minimal guidance
• Experience working with Kotlin and Java in a production codebase
• Strong communication skills to align with stakeholders across tribes and functions, in English
