Senior Reservoir Engineer / Subsurface Simulation Expert Geothermal CCUS

The ETH Zürich Geothermal Energy & Geofluids Group (GEG) investigates reactive fluid and (geothermal) energy transfer in the Earth's crust, employing computer simulations, laboratory experiments and field analyses to gain fundamental insights and to develop sustainable technologies that address society's needs.
One of these technologies (co-invented by Martin Saar) is CO2-Plume Geothermal (CPG), which turns CCS into CCUS by extracting geothermal energy using CO2 whilst simultaneously sequestering all CO2.
To advance this technology, a Senior Reservoir Engineer / Subsurface Simulation Expert is needed, starting 1 April 2025 or later upon agreement.
Job description We are seeking an individual who is highly motivated to provide quality subsurface evaluations of CPG and other Geothermal CCUS processes, ranging from the development of high-level portfolio screening tools to detailed compositional reservoir modelling.
You will integrate and quantify the uncertainty of (subsurface) data for model development, requiring knowledge of, and ability to collaborate with, multiple disciplines ranging from geosciences (geology, geochemistry, geomechanics, etc.) to mechanical engineering (CO2-based geothermal power plant design) and techno-economics (of geothermal power plants and CCUS).
Leveraging your expertise and modelling insights, your innovative thinking extends the state-of-the-art of geothermal CCUS technology and drives the development of high-value projects together with industry partners.
Profile You have a university degree (MSc or PhD) in Geoscience, Engineering, Mathematics, Physics or equivalent technical subject and at least 4 years of reservoir simulation experience in the industry, as well as:

Theoretical and practical knowledge of 3D compositional, multiphase and non-isothermal reservoir simulations, ideally in the domain of CCS or CO2 EOR/EGR.
Geothermal energy modelling experience is a plus.
Proficient in reservoir simulation tools (CMG / SLB / RFD or equivalent).
Experience working in multi-disciplinary teams, with exposure to geology, geomechanics, petrophysics, production chemistry, production technology, well engineering, facilities/power plant components and economics.
Knowledge of Petroleum Engineering fundamentals (PVT, SCAL, MBAL, PTA).
Understanding of methodologies to assess and quantify subsurface uncertainty.
Experience in data analytics and visualization (use of Python or equivalent).
AI/ML experience is a plus.
Exposure to field piloting, surveillance planning and/or field development planning is a plus.
Self-motivated team player with strong interpersonal skills and the ability to work in a multicultural environment.
Coaching / mentoring experience preferred.
Strong analytical and problem-solving capability.
Experience publishing research results in peer-reviewed publications is a plus.
Experience in project management.
Fluency in English is required.
We offer We offer a dynamic and exciting work environment at the cutting edge of emerging energy technology with the potential to deliver large-scale power while geologically sequestering CO2.
The position is for one year with the strong possibility of yearly extensions during a 2- to 5-year period, depending on the project and employee performance.
