At SumUp we are building innovative solutions to support small merchants to start, run, and scale their business. We offer a diverse range of products that integrate seamlessly into our user’s lives by pushing the boundaries of financial technology. From concept to deployment, you will play a key role in shaping the future of our products.

SumUp has a SuperApp that hosts all of the different products we offer to our merchants – from business accounts to invoicing to managing payments. You’ll be an integral member of our development team, and have the opportunity to contribute to creating groundbreaking mobile applications that set new standards in user experience and functionality.

We take our engineering excellence seriously at SumUp and you have various exciting opportunities to work with a team of highly skilled engineers on products such as SumUp Pos, SumUp Business Accounts, Online Payments and many more.

About the team
You’ll 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 verticals: maintaining CI/CD for Mobile projects, creating tooling for developers, and 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 merchants succeed – join us!

What you’ll do

  • In the first few weeks, you’ll dive into the code and infrastructure, and get to know our development workflow
  • 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 differently 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 cleanly

You’ll be great for this position if

  • You have experience with Kotlin and the Android framework
  • You know what to test, why to test it, and how to write flexible tests that won’t break
  • You care about user interaction and usability, and have attention to detail
  • You love coding and take the time to reflect on all aspects of your implementation, be it the frameworks, languages, or processes
  • You strive for clean code but also know how to be pragmatic when needed

Why you should join SumUp

  • The opportunity to work on large-scale fintech products used by millions of small businesses around the world
  • Work as part of a cross-functional high-impact squad
  • A dedicated annual Learning & Development budget for attending conferences and/or advancing your career through further education

  • A corporate pension scheme
  • You’d enjoy other great benefits such as Urban Sports Club subsidy, Kita placement assistance, subsidized office lunches and other location-tailored benefits, Babbel language platform subscription and more
  • Join a truly global SumUp team of 3200+ people from 80+ countries, spread across 4 continents
