Job summary

ETH Zurich’s Geothermal Energy & Geofluids (GEG) Group seeks a Process & Energy Systems Modeling Engineer/Scientist for physics-based numerical modelling, software development, and engineering analysis of energy systems, from geothermal plants to fluid and mineral processing facilities.

A core focus is co-developing an open-source power plant and wellbore flow simulator integrated into TANGO, coupled with RAFT, for techno-economic evaluations and scalable simulation across direct heat, power,

Qualifications

PhD in Mechanical Engineering, Process Engineering, Chemical Engineering, Energy Engineering, Thermal Engineering, Computational Engineering, or related field.
Strong grounding in engineering thermodynamics, fluid mechanics, heat transfer, and energy conversion systems.
Proven capability to develop physics-based simulators and models in scientific software with version control and testing.
A passion for translating physics into robust numerical tools and for practical software creation.

Responsibilities

Formulate, implement, and maintain numerical models and software for energy and process components (heat exchangers, turbines, pumps, separators, piping, wellbores).
Simulate, optimise, and analyse integrated energy conversion systems (geothermal plants, ORC, CO2 facilities, process streams).
Perform techno-economic assessments (LCOE, LCOH, NPV) and cost estimation.
Develop and apply coupled surface–subsurface models for fluids, heat transfer, and pressure/temperature evolution.
Write clean, modular scientific code with Git, tests, and documentation.
