Senior iOS Engineer - Platform

Berlin, Germany · Mobile

At SumUp we are passionate about giving access to financial services for the millions of businesses that are considered too small for most providers. They’re as much as 10 times smaller than the smallest businesses that would be targeted by banks and traditional providers. What started out as one card reader has now turned into a range of readers, multiple remote payment solutions such as Invoices, Gift Cards, Payment Links and so much more.

As a Senior iOS Engineer you will be connecting SumUp's platform and enabling squads to seamlessly integrate their products into a cohesive experience. The Platform team strives to maintain and improve our mobile apps and tools in order to ensure more stability, quality and flexibility for both our mobile engineers and our merchants alike.

What you’ll do in this role:

  • Help evolve our mobile Point-of-Sale solution, an integral part of SumUp, used by millions of people around the world.

  • Collaborate with an international team spanning 3 continents and 8 cities, made up of other engineers, designers and product managers to develop simple and delightful solutions for our merchants.

  • Write high quality and testable code that implement these solutions.

  • Take an active role in mentoring your peers on engineering principles, design and implementation.

You will be great for this position if:

  • 5+ years experience working on large scale iOS projects

  • You have solid expertise in Swift
