Mission Context : The team you will join develops and maintains several software products linked to real‑time operation and optimization of energy assets, including: Real Time Control Services : These services receive control signals every few seconds from grid operators or optimization algorithms, compute the optimal allocation across assets (e.g., batteries, renewable parks), and send the corresponding setpoints back in real time. Low Latency Data Acquisition & Streaming : A dedicated component continuously collects and processes real‑time telemetry from physical assets (electrical data, performance data, status indicators). This data is made available to forecasting engines, optimization algorithms, visualization tools, and other internal systems through high‑throughput, low‑latency data streams. Connectivity Between IT and Industrial Systems : The system integrates with industrial supervisory systems (SCADA), enabling secure and reliable data exchange. You will collaborate with architects, developers, analysts, and business/domain experts to design and evolve these platforms.
