Join GEUS' research tema and develop tools to protect groundwater resources
The Geological Survey of Denmark and Greenland (GEUS) plays a central role in groundwater protection in Denmark. GEUS invites applications for a 2-year postdoc position. The postdoc will work at the intersection of geology, geochemistry and machine learning, exploring relationships between geological structures, lithology and sediment colors, redox conditions, and groundwater quality. The position is based in Aarhus and you will work with a specialized and diverse team of researchers. We offer an opportunity to dive into big data sets and produce valuable knowledge that furthers the best use of groundwater resources.
About the position
We are looking for a highly motivated postdoctoral researcher to investigate how geological structure and lithology properties are interconnected with subsurface redox conditions and groundwater quality in Danish aquifers. The project will combine big datasets of borehole lithology and sediment color descriptions, where sediment colors has been interpreted as a proxy for redox conditions. These datasets will be integrated with extensive groundwater chemistry data to better understand connections between redox architectures, groundwater chemistry and geological structures.
You will be part of a large Innovation Fund Denmark project called PROTECT – Groundwater Protection in a Changing Landscape (https://protect.geus.dk/) where we are developing and applying technologies and creating knowledge for the protection of Danish groundwater resources in conjunction with other environmental and nature goals. The project runs until 2029 with possibilities for a high degree of collaboration with the other eight partners from different research institutions, authorities and a private company.
Who are you?
You hold a PhD in geoscience, geochemistry, environmental engineering, hydrogeology, and data science or a related field. The ideal candidate has one or a combination of the following qualifications:
You must be able to communicate in English, and since the primary language of the organisation is Danish, you should be prepared to learn Danish.
Meet your new colleagues
You will become part of the Department of Geochemistry. The department researches the fate of chemical substances in the entire water cycle, but with a particular focus on soil, groundwater and drinking water as well as the deeper underground. The activities are characterized by a high degree of experimental work in the form of laboratory and field trials, which are often supplemented with numerical models. Our research includes naturally occurring substances such as nutrients as well as microbiology, pesticides and other harmful substances, and we have as a common denominator that we would like to create knowledge that can contribute to a better environment for future generations.
We are broadly based professionally with, among others, engineers, geologists, environmental chemists and microbiologists, all of whom work with groundwater-related data, e.g. in relation to the national groundwater monitoring as well as to understand geochemical processes in the subsoil, e.g. in connection with CO2 storage, pollution with natural and environmentally foreign substances, nitrate in groundwater and surface water, etc.
We are approx. 40 employees divided into administrative staff, technicians and researchers at different stages of their careers.
A working environment with a focus on professional development and well-being
There are many good reasons why you should choose a working life at GEUS.
We are a diverse staff of about 300 committed employees. Trust and flexibility are keywords. The working environment is lively, informal and international. Our tasks are versatile and there are plenty of opportunities for you to influence the development of your task portfolio.
We prioritise professional development, among other things by offering access to courses and other relevant activities. Socialising is also very important at GEUS, and we have a rich social life with a staff club, an art association and more.
At GEUS, we prioritise the well-being of every single employee. We prioritise that the Heads of Departments are close to the employees, and we have flexible working hours that allow you to organise your life so that there is time for what matters to you. If you need to work from home occasionally, that is also possible.
Salary and terms of employment
Salary and terms of employment are in accordance with the relevant trade union agreement.
The appointment area is the Ministry of Climate, Energy and Utilities and its institutions.
The Ministry of Climate, Energy and Utilities considers diversity to be an asset and encourages anyone regardless of gender, age, religion or ethnicity to seek the position.

If you are a foreign applicant, you can read more about living and working in Denmark on GEUS’ website.
Are you interested?
If you are interested in the position, we would like to hear from you. The application must include a CV, incl. your ORCID, a list of publications with a separate indication of articles registered in ISI Web of Science and any copies of individual publications of particular relevance to the position.
Also enclose a master's and Ph.D. certificate in either Danish or English. If you do not yet have a Ph.D. certificate, you must have submitted your Ph.D. before the application deadline and attach the Ph.D. dissertation along with a receipt for submission.
Please submit the application via GEUS’ website at the latest on Sunday 30 November 2025.
Applications or other material received after the deadline will not be considered.
The employment procedure
A professional assessment committee consisting of two internal assessors at minimum senior researcher level will carry out an individual assessment of all applicants’ professional qualifications, and the applicants will be assessed as qualified or unqualified for the position. Afterwards, an internal employment committee will decide which of the professionally qualified candidates will be invited for a job interview. This procedure is in accordance with the “Order on employment and assessment of scientific staff at the Geological Survey of Denmark and Greenland § 4 and 7”.
As part of the recruitment process, we may find it necessary and choose to make a background check as part of a security risk assessment.
