Research Assistant (f/m/d) Research Group „Co-Simulation of multimodal Energy Systems” (COM)

Save as a favourite

For the next two years and possibly beyond, we are looking for energetic full-time support at our Oldenburg site for our research and development area Energy in the "Co-Simulation of multimodal Energy Systems" group.

The challenges of the future energy system are immense and an interesting field to work in. New approaches can lead to relevant contributions for the energy transition. For this purpose, the research group “Co-Simulation of Multimodal Energy Systems” develops simulation methods, interfaces for the integration of different simulation tools, models for components in the energy system and best practices for the design and execution of simulation experiments.

Our open-source co-simulation framework “mosaik” ( is widely used in the community for energy research. In a new project, we aim to further expand the capabilities of mosaik and to extend the possibilities to couple mosaik to other relevant tools of the domain.

The COM group specializes in simulation-based system analysis for the development and validation of new components and architectures of the distribution grid. A modular co-simulation approach is used, which allows different aspects of the energy system to be combined via partial models in the simulation framework "mosaik". Mosaik enables the integration of independently developed simulation models, regardless of their domain or formal description.

What you enable:

  • You deep dive into the way mosaik works and develop, together with our mosaik team, new features of mosaik to make it ready for the next challenges in energy research.
  • Together with our project partners and our internal team, you do research in the field of co-simulation of energy systems and publish you research in scientific journals and conferences.
  • You bring in own ideas for the future of mosaik and work on parts of mosaik on your own.
  • You develop software interfaces between simulation tools.

What you bring to the table:

  • Master‘s degree in computer science or a comparable computer science-related field
  • Interest in pursuing a PhD, in scientific work, the publication and presentation of scientific papers
  • Profound knowledge of software and system architectures, programming, and open-source software
  • You can develop in object-oriented high-level programming languages (preferably Python) or in other object oriented languages and have first experience with the automation and structuring of development processes (e.g. CI/CD, DevOps)
  • Git, REST, and Docker are already familiar to you.
  • You have a keen interest in learning new topics in computer science.
  • Good knowledge of German and English, both written and spoken

What we offer you:

  • You can look forward to a working environment that is very pleasant in human terms and extremely interesting in technical terms.
  • We actively support you in your further professional and scientific qualification through close cooperation with the Carl von Ossietzky University Oldenburg.  The project offers the opportunity to work on a doctoral thesis when meeting the necessary requirements.
  • Work-life balance is important to us - we support this with flexible working hours, consideration of part-time options and home office, among other things.
  • Tolerance, openness and equal opportunities towards people of all genders (m/f/d) are important to us.
  • We would like to continue to increase the proportion of women in our workforce, which has been rising for years.
  • We give preference to applications from severely disabled persons who are professionally suitable.
  • Your position is limited to 24 months with the option of extension and is paid according to TV-L 13.
