Android Developer

Berlin, Germany · Mobile

As an Android Engineer you’ll be part of the team working on the backbone of Mobile Engineering at SumUp – creating and maintaining a development environment that enables Mobile Developers to ship high quality products and provide help and guidance to all SumUppers that interact with the mobile apps. 

To be successful in this role you should be able to follow good software engineering principles, write clean code and tests, and be open to constantly learning and improving your craft. It will be expected from you to not only ship features, but also to contribute to the decision making process.

You should be a mobile engineer with a product mindset who can fully own the features you are working on and remain flexible with changing priorities.

This position is On-site.

About the team

Our team is autonomous and engineering-driven by nature. You will be able to connect with mobile engineers from all over the company as our initiatives are far-reaching. You’ll experience a wide range of different challenging verticals: maintaining CI/CD for Mobile projects, creating tooling for developers, providing infrastructure & architecture supporting our modularised codebase. We maintain a high bar in engineering and aim to continually increase it. Our initiatives have long-term impact at scale. We believe in open communication and constant learning over strict rules. If you're looking for the chance to innovate and help millions of small independent merchants succeed - join us!

What you’ll do

You’ll shape the mobile developer experience of other Android developers at SumUp.

In the first few weeks, you'll dive into the code and infrastructure, and get to know our development workflow. You'll use this knowledge to start developing and refining features. You'll get to know the tools that power our processes, how we test them and how we sustain efficient workflows.

You'll develop major features that impact our developer community. You'll work closely with the rest of the team to drive our roadmap and design our developer experience. You'll help us rethink problems we've solved before in a different way as requirements evolve.

You'll build a wealth of knowledge about our complex problem domain, as well as its implications on the long-term health of our project – and how to manage it in a clean way.

  • You know what to test, why to test it, and how to write flexible tests that won't break.

  • You care about user interaction, usability, and have attention to detail.
