Limited contract until:

Job ID: 4874

The position is part of the Solar System Evolution group led by Ass.-Prof. Kristina Kislyakova. The main research direction of this group consists of unraveling the evolutionary pathways of the Solar System bodies, in particular Earth, Venus, and Mars, and determining the place of the Solar System within the larger family of exoplanets.

Your working place:

The Department of Astrophysics with currently around 90 members is part of the Faculty of Earth Sciences, Geography and Astronomy at the University of Vienna. We are searching for a Senior scientist to contribute to the development of numerical codes used by the Solar System Evolution group and other groups at the department. Our ideal candidate has a scientific background in the evolution of stellar and planetary atmospheres and strong background in computational astrophysics and software development.

The job consists of two equally important parts: 1) to contribute to the research in the area of atmospheric evolution with the focus on atmospheric escape and 2) to take the lead in developing and supporting computational tools for atmospheric studies, such as finding the best solvers that can be used in the codes used by the Solar System Evolution and other groups at the department.

The position is initially limited to 3 years with possibility to become permanent by mutual agreement. The starting date is as early as February 1st, 2026, but no later than June 1st, 2026.

Your future tasks:

You build an excellent research profile in the field of planetary and stellar atmospheres, and Solar System research

• .
  You lead and participate in scientific publications in peer-reviewed journals and presentations at international meetings- .
  You take the lead in the application of new computational tools, such as solvers, to the existing codes used by the group such as the hydrodynamic atmospheric codes for planetary and stellar atmospheres and particles codes- .
  You contribute software expertise to other computational astrophysical groups- .
  You (co-)supervise Bachelor, Master, and Doctoral students in Astronomy- .
  You hold courses independently within the scope of the provisions of the collective bargaining agreement- .
  You take on administrative tasks in research and teaching as well as evaluation procedures- .
