Role Overview As we continue to look for more sustainable ways to build, we need world-class talent to join our team. People who are passionate about sustainability, driven by curiosity, and keen to grow, learn, develop, and thrive in our high-performance culture.

We are looking for an innovative Process Data Scientist , motivated to solve the bigger operational and energy challenges in our industry. Inspired to develop and deploy cutting-edge AI applications that enhance a new era of kiln and thermal efficiency, our Process Data Scientist is passionate about leveraging digital tools to optimize process stability, reduce fuel consumption, drive Alternative Fuel substitution, and curb CO2 emissions across our Plants of Tomorrow.

You will work on the algorithm design, Machine Learning development and deployment, and implementation of various manufacturing process optimisation initiatives including our flagship solution P-PREDICT .

You will also make sure these solutions integrate seamlessly our legacy and new Plant of Tomorrow technologies to realize our vision for sustainable cement manufacturing.

Main Responsibilities Machine Learning & Physics-AI Hybrid Model Design, Tuning, and Validation:

• 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).

Model Lifecycle Management

• 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.

Explainable AI (XAI) & Operator Interface Integration

• 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.

Field Adoption & Knowledge Transfer

• 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.

Your Profile Level Of Education/qualifications Normally Required

• MS or PhD in Computer Science, Chemical Engineering, Data Science, Electrical Engineering, Systems & Control, or equivalent fields.
• C3.ai Certifications (C3.ai Data Science, C3.ai V8 Data Science/Application Development) or equivalent enterprise AI framework certification (Advantage).

Experience

• 3+ years’ experience in applied Machine Learning and Data Science projects focused on heavy industry process optimization (cement, chemical, energy, or mineral processing preferred).
• 2+ years’ experience productizing and scaling ML models in production environments (both Cloud and EDGE).
• 2+ years’ experience in industrial change management, coaching, and technical knowledge transfer to guarantee full plant adoption of digital control systems (Advantage).

Technical Competencies

• Applied Machine Learning expertise: Anomaly detection, time-series forecasting, regression analysis, probabilistic modeling, supervised classification, and unsupervised learning.
