Fullstack Developer - Python & React (m/w/d)

Wir entwickeln eine moderne, KI-gestützte Prozessautomatisierungsplattform — von der Analyse von SAP-Workflows bis zur automatisierten Generierung von Dokumentationen und Präsentationen. Unser Stack ist durchgehend modern: Python 3.13, FastAPI, React 19, PostgreSQL und Azure-Cloud-Infrastruktur.

Du arbeitest eng im kleinen, agilen Team an einem System, das echten Einfluss auf Unternehmensabläufe hat — kein Buzzword-Bingo, sondern produktiver Code, der täglich im Einsatz ist.
