(Senior) Software Engineer (m/f/d) Industrial IoT

ABOUT THE TEAM

We are an international team building KINEXON OS, the operating system that optimizes visibility and transparency of industrial moving assets. Our platform captures real-time location data and provides dynamic workflows, delivering actionable insights for production and logistics.

KINEXON OS is open, flexible, and scalable, enabling full visibility into supply chains and dynamic tracking of assets for swift operational decision-making. It aggregates position and identification data from various sources and enriches it with contextual information from third-party IT/OT systems such as ERP, MES, and WMS.

Join us to shape the backbone of a platform that powers digital transformation in manufacturing and logistics worldwide.
