The Geothermal Science and Technology group (Prof. Dr. Ingo Sass) invites applications for the position of a

Research Assistant (all genders) – 75%

starting as soon as possible and initially limited until December July 31, 2025. This vacancy is part of the BMBF funded PotAMMO program.

The overall objective of the PotAMMO project is to determine the potential for integrating Aquifer Thermal Storage Systems (ATES) into the heating grids of Mannheim and Offenbach regions in the Upper Rhine Graben. Not only technical aspects, but also economic and ecological evaluation criteria should be included in the potential analysis and help to identify suitable ATES locations for the most profitable but also cost-efficient integration. The project aims to develop a methodology for identifying ATES potential that can be transferred to various other regions.

Within the project, three researcher positions are planned. The first position will work to generate 3D geology structural models of both regions. These models then will be used by a second researcher for numerical modelling. Finally, another researcher will work in the life cycle assessment direction. The project is managed by Section 4.8, GFZ Potsdam.

We are looking here for a talented and motivated geologist to generate 3D geology structural models for Offenbach and Mannheim regions. The position is employed by TU Darmstadt and will be supervised by GFZ Potsdam, Section 4.8 Geoenergy.

Your tasks:

  • Identification of potential aquifer storage sites
  • Detailed modelling of designated storage horizons from geophysical and structural data
  • Publication of research results in peer-reviewed scientific journals
  • Present results before scientific audience

Your skills:

  • Experience of geophysical and well data interpretation
  • Experience in sedimentary and fractured reservoir models (geological modeling, basin modeling, DFN, structural)
  • Experience in mechanical modeling is a plus
  • High level of knowledge in structural and sedimentary geology,and of geothermal reservoirs


  • University degree (Dipl. Univ./Master) in Applied Geology or Geophysics or related fields
  • High proficiency in German and English.

Other desirable skills:

  • Experience and/or willingness to work in cooperative scientific teams
  • Skills in interdisciplinary, on-time, goal- and team-oriented work
  • Extended knowledge of the modelling of reservoir systems by hydrogeological and geothermal characteristics

We offer:

We offer a professional research environment as well as support in the presentation and publication of research results at national and international conferences and in specialist journals. Additionally, there will be many opportunities to work with international collaboration partners from academia and industry through our joint research projects. Modern computer and laboratory equipment is available.

Opportunity for further qualification (doctoral dissertation) is given. The fulfillment of the duties likewise enables the scientific qualifications of the candidate.

The Technische Universität Darmstadt intends to increase the number of female employees and encourages female candidates to apply. In case of equal qualifications applicants with a degree of disability of at least 50 or equal will be given preference. Wages and salaries are according to the collective agreements on salary scales, which apply to the Technische Universität Darmstadt (TV-TU Darmstadt).

Please send your application including a letter of motivation, a CV and relevant certificates (all in one single pdf file) to Mrs. Simone Roß-Krichbaum, Sekretariat Angewandte Geothermie ( referring to PotAMMO and the given Code-No.

Please do not hesitate to contact Dr. Claire Bossennec by e-mail,, +49 6151 16-22096, if you have any further questions.
