Role and responsibilities
Design, configure, and validate hybrid Machine Learning algorithms combining 1st-principles process physics and adaptive AI loops for calciner and kiln optimization. Develop predictive soft sensors for real-time process variables, like fuel calorific value forecasting of alternative fuels and clinker quality predicting. Build multi-variable target recommenders for control loops of our kilns and other equipment. Use deep learning, time-series forecasting, and probabilistic models to predict operational hazards (such as ring formation risk, cyclone blockages, and pressure spikes). Responsible for the end-to-end lifecycle of models (including feature engineering, design, cloud/edge deployment, continuous tuning, and automated retraining pipelines). Work with our vendors on the deployment and customization of their solutions as well as on development of Holcim proprietary solutions. Design operational logic, reason codes, and metrics to be displayed on operator dashboards to ensure high explainability and user trust. Collaborate closely with process engineers and plant operators to translate operational knowledge into accurate model boundaries. Drive global uptake and utilization of P-PREDICT and other PoT initiatives across the world, through structured plant onboarding, commissioning support, and feedback loops. Provide coaching, knowhow transfer, and technical documentation for plant process engineers.
