This role sits at the intersection of process engineering, applied mathematics, and machine learning, with a strong focus on real-world industrial impact.
You will work closely with engineers and plant operators to:
Improve operational efficiency
Reduce cost and environmental footprint
Increase understanding and robustness of our systems
How you'll make an impact:
Develop predictive models for water treatment processes (e.g., ACF, IEX, RO)
Data-driven models (regression, tree-based methods, etc.)
Physics-informed or hybrid models
Translate operational data into actionable insights
Build simple, robust models that can be used by engineering and operations teams
Analyze plant performance to identify optimization opportunities
Work with multidisciplinary teams (process, automation, software)
Support deployment of models into engineering tools or operational workflows
Participate in on-site visits internationally to understand systems and validate models
Qualifications:
We are looking for a hands-on problem solver who can bridge theory and real-world systems.
Must-have:
MSc or PhD in:
Applied Mathematics, Data Science, Chemical Engineering, Environmental Engineering, or similar

Good programming skills (Python preferred: pandas, NumPy, scikit-learn, etc.)
Solid understanding of:
Ability to work with noisy real-world data (not clean academic datasets)
Fluent in English
Additional Qualifications:
What makes this role unique:
Work on real industrial systems, not abstract datasets
Direct impact on sustainability and water circularity
Opportunity to shape the digital transformation of water treatment plants
Combination of:
Field understanding
Engineering
Data science
