How you'll make a Difference:

• Partner with stakeholders to turn business needs and scientific questions into data-driven strategy

• Design, develop, and enhance ML models for catalyst performance prediction

• Apply advanced analytics techniques, exploratory data analysis, feature engineering, model selection, hyperparameter tuning, and model performance assessment

• Document model assumptions, methods, validation results, and recommendations in a reproducible way

• Explore relevant databases and available data sources to understand data structures, completeness, quality, and usability for modelling

• Unlock insights from correlations, patterns, outliers, and potential performance drivers within catalyst, emissions, laboratory, product, and process data

• Develop scalable workflows that support efficient re-use of cleaned datasets

• Work with catalyst, process, product, and laboratory data to identify performance drivers and relevant modelling features

• Help advance the transition from exploratory analysis and prototype models to robust, usable modelling assets for the Project Team

• Communicate insights and recommendations in a clear, compelling way that inspires action across technical and non-technical stakeholders

You'll stand out with these Skills:

Technical - mandatory
