Start: As soon as possible

I will play a critical role to design and develop seamless integration of various industry protocols.
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 as well as I`ll be actively contributing to the systems architecture. I will have the chance to integrate 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. The Adaptation Suite is an integral part of the Grid Asset and System Platform (GrASP), providing seamless integration and compatibility with various industry protocols, SCADA systems, and file operations. Leveraging the power of Apache Camel in the background, it acts as the middleware that transforms and routes messages effectively, ensuring smooth communication across the system.
