SumUp | Berlin | (Mid/Senior) Elixir Engineer | Onsite | Visa supported
We are looking for a backend engineer in the Hardware tribe to help us maintain and improve our devices. Our mPOS and printers delegate a significant part of the payment logic to the backend, giving us the flexibility and development speed which our merchants require from us. As a backend engineer, you will support our team with delivering new features to one of those devices and maintaining existing ones - transaction flows for different payment methods, firmware updates, and other integrations with our internal services. You will also migrate and maintain our terminal backend infrastructure, which includes assets management, card payment processing, hardware configuration, logging and monitoring.
