You will own core product across the entire stack, directly shaping both the technology and the company's trajectory. The work touches real-time optimization, AI-driven forecasting, and infrastructure that manages significant energy assets across Europe. What You'll Do Own and build the core product driving real-time optimization and forecasting for industrial energy assets. Develop backend services and mixed-integer optimization algorithms to process data in real time. Create frontend dashboards that allow battery operators to monitor and control their assets.
