technical assistant (m/f/d)

Deadline: 12th January 2026

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation under public law jointly financed by the Federal Republic of Germany (90%) and the State of Schleswig-Holstein (10%). It is one of the internationally leading institutions in the field of marine research.

Through our research and our commitment to the transfer of knowledge and technology, we contribute significantly to the preservation of the function and protection of the ocean for future generations. As part of the LiMare consortium funded by the BMWE, an approach will be developed that will enable extractions of critical raw materials from seawater in a selective and environmentally friendly manner. The sub-project “Determining the impacts on the marine ecosystem” aims to provide a risk assessment for this new technology.

The Geomicrobiology group in the research unit Marine Geosystems is offering one position for a

technical assistant (m/f/d)

starting as soon as possible. The position is limited to 36 months, subject to approval.

The Geomicrobiology group studies microbial communities from the sea floor - from shallow water to the deep sea. In light of ongoing anthropogenic activities, it is of fundamental importance to understand how microorganisms and their metabolisms are influenced by changing environmental conditions and how they in turn shape their environment. Established methods the Geomicrobiology working group uses to address these aspects include molecular biological approaches as well as cultivation-based techniques such as incubation experiments, cultivation and rate measurements.

Job description/Project description

You will conduct incubation experiments with sediment cores and the overlying water column in order to produce a well-founded risk assessment of a newly developed process for the selective and environmentally friendly extraction of critical raw materials from seawater. In doing so, you will implement different experimental approaches, take subsamples at defined times, and perform cell count determinations as well as taxonomic, functional, and chemical analyses. The methods used include classical microbiological and molecular biological laboratory techniques for analyzing microbial diversity and functionality.

Qualification

Requirements:

Completed training as a biology lab technician, chemical-technical assistant, or biological technical assistant, or comparable qualification
Extensive practical experience in classical microbiological and molecular biological methods
Experience working under sterile laboratory conditions and with microbiological cultivation techniques
Willingness to participate in sea-going expeditions
Very good written and spoken German

Desirable:

Experience in DNA and RNA extraction from sediments and environmental samples
Experience in preparing DNA/RNA material for Illumina sequencing
Knowledge of fluorescence in situ hybridization (FISH) and specific staining methods; experience with light and fluorescence microscopy
Basic understanding of microbiological metabolic processes
Experience with sensor technology and microprofile measurements
Experience in data analysis with Excel or R, including sequence data analysis
Practical field and ship experience, especially sampling and sediment core work
Flexibility in changing tasks and willingness to undergo further training
English skills are an advantage

At a workplace, directly on the Kiel Fjord with many leisure and recreational opportunities, we offer you:

Support services for professional and personal life situations
An exciting work environment with the opportunity to provide important impetus for the development of sustainable solutions
Exciting topics in an international environment
Work in the field of marine and climate research, a forward-looking area with social significance
30 vacation days + additional time off at Christmas Eve and New Year's Eve
Company pension plan and capital-forming benefits

The position is limited to 36 months, subject to approval. Remuneration is based on pay scale E9a (TVöD-Bund) if the relevant requirements are met. The regular weekly working hours correspond to those of a full-time employee. The position can be split, provided that it is filled on a full-time basis. Flexible working time models are generally possible.
