Postdoctoral Researcher on hybrid AI-optimization modelling

100%, Zurich, fixed-term

The Energy Science Center (ESC) at ETH Zurich is an interdepartmental competence centre that facilitates energy research and teaching activities across research fields and departments, and promotes outreach and public visibility of energy research at ETH Zurich. We are seeking a highly qualified and motivated Postdoctoral Researcher to join our team working at the forefront of hybrid AI-optimization modelling. This position focuses on the design of AI-based surrogates of large-scale energy system models and will be integrated in the activities of the Nexus-e group with close links to the ETH AI Center and the Reliability and Risk Engineering Lab .

Job description

• Collaborate with other researchers to develop high-fidelity emulators for large-scale, energy system optimization models
• Lead the design and implementation of innovative methods, which could include but are not limited to: Kriging surrogate, Polynomial Chaos Expansion (PCE), and Physics-Informed Neural Networks (PINNs)
• Contribute to the strategic direction of research
• Publish high-impact research in leading journals and present findings at international conferences on energy systems and machine learning
• Collaborate with industry partner to tackle challenges of practical relevance

Profile

Interested candidates should meet the following requirements to be eligible for the position:

• A PhD or Doctoral degree in Energy Systems, Computer Science, Applied Mathematics, or a field focused on the intersection of Machine Learning and Optimization
• Proven expertise in surrogate modelling, specifically in designing neural architectures for emulating constrained optimization problems
• Advanced programming skills in Python, with deep experience in libraries such as PyTorch, Pyomo, and the broader scientific stack (Xarray, Pandas). Knowledge of MATLAB is desired but not a requirement
• A strong track record of publications in peer-reviewed journals involving advanced emulation or physics-aware AI
• Demonstrated ability to work effectively in interdisciplinary and multicultural research teams, bridging the gap between data science and energy engineering
