In this role I will play a critical role to develop the real time data management in the Grid Control System of the Future

That makes this job interesting for me: As a lead developer I will also guide the development team on how to build scalable and reliable solutions for real time data management as well as I will be actively contributing to the systems architecture. I will have the chance to integrate in a product organization which is developing the Next Generation Control Center Ecosystem MCCS (Modular Control Center System) to meet the requirements of digitalization in the energy transition. MCCS aims to replace classic, monolithic SCADA applications and other operational tools with modules that run in Kubernetes clusters and exchange data via streaming services.
