About the Role
Join SumUp as a Senior Embedded Engineer within our Hardware Tribe, where you will collaborate with a talented cross-functional team of Hardware Engineers, Product Managers, QA Engineers, and more. Your expertise will be pivotal in developing our innovative Android-based payment devices, guiding the process from bootloader and kernel development to framework integration and validation.
This is an exciting opportunity as we transition to using the Android platform for our proprietary hardware solutions. Our payment devices are uniquely designed with a focus on security and customization, necessitating a profound understanding of both embedded hardware and software.
This position requires on-site presence in our Berlin office, as we value the organic interactions that emerge from working closely together.
About the Team
You may have already encountered our card readers while enjoying a cappuccino or settling a bill at your favorite salon.

We tackle a variety of engineering challenges spanning industrial and electronic design, embedded systems, mobile applications, and backend services.
