Senior Software KI Engineer – Payment (m/f/d)

Every time you pay at the checkout – whether with card, gift card or bar – processes and software run in the background to ensure that it works reliably, securely and in real time. You are responsible for this: for the systems that make payments at dm international possible. Payment at dm is not a completed project, but a topic that is constantly evolving – and the way we build software is developing at least as quickly. We are increasingly focusing on AI-based development ('Agentic Coding'', Development Factories) – the responsibility for what is going on in the end always remains with humans. The real challenge is no longer to tip code, but to penetrate requirements so precisely, to guide and control AI-based processes in such a way that reliable, secure systems are created from them – especially in a regulated environment such as payment, the claim to you is increasing instead of sinking. This is exactly what we are looking for: someone who analyzes complex technical and technical relationships cleanly, translates them into clear specifications, orchestrates AI-based development processes and takes full responsibility for the result – from the architecture of new services to the connection of card terminals and adjacent systems (cash, app, ERP).
