University of Vienna seeks a Scientific Project Assistant (predoctoral) to join a marine microbiology project. You will sample sea surface microlayer and underlying waters, participate in a major oceanographic cruise, and lead single-cell activity assays while developing metagenomic data analyses.
You will work 30 hours per week over 3.5 years, with doctoral training through the VDSEE and opportunities to present at international meetings. English is the working language.
At the University of Vienna, almost 11,000 people work together on the big questions of the future. Approximately 7,700 of them are academic staff members. These are individuals who, with their curiosity and their continuous pursuit of excellence, engage in international cutting‑edge research and teaching. With us, you will also find space to unfold your potential.
We are looking for an enthusiastic, curious and communicative colleague who enjoys working in the laboratory, in the field and at sea as part of an international team. Does that sound like something for you?

Startdate: 01.02.2027 | Working hours: 30 | Collective bargaining agreement:
The working group of Marine Microbial Biogeochemistry at the Department of Functional and Evolutionary Ecology of the University of Vienna investigates how microorganisms shape carbon cycling and biogeochemical processes in the ocean, from coastal waters to the deep sea.
As a scientific project assistant (predoctoral), you will join the research team around Dr. Thomas Reinthaler in the FWF-funded project “Variability of Ecologically Relevant Bacterioneuston (VERA)”. The project is carried out in collaboration with the University of Oldenburg and is embedded in a larger research group with prominent German universities and research institutes.
You will investigate which bacteria are active in the sea‑surface microlayer, the boundary layer between ocean and atmosphere, and how they vary over a seasonal cycle and along an Atlantic transect. By combining single‑cell activity measurements with metagenomics and metatranscriptomics, you will identify the traits that allow key taxa such as SAR11 and Roseobacteraceae to thrive at the air‑sea interface.
The start of the contract is 1 February 2027. The employment period is 3.5 years from the beginning of the contract.
As a team, an open, collaborative and respectful working environment is important to us.
The employment duration is 3.5 years at 30 hours per week (75%). Doctoral training and degree‑related activities are additional to the contracted hours.
Our employees enjoy flexible working hours and can partially work remotely, apart from fieldwork and cruise periods.
You are part of an international academic team in a healthy and fair working environment, with access to state‑of‑the‑art facilities for microbial ecology and to the Life Science Compute Cluster of the University of Vienna.
Your workplace is easily accessible by public transport.
Opportunity to deepen your skills on an ongoing basis. There are over 600 courses to choose from, free of charge. As a member of the Vienna Doctoral School of Ecology and Evolution you also have access to structured doctoral training.
Equal opportunities for all: We welcome every additional/new personality to the team!
The Welcome Compass helps you settle into your new role at the University of Vienna and life in Vienna.
