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 looking for a Senior Scientist to join the Dynamics of Stellar Systems research group led by Prof. Glenn van de Ven. Our ideal candidate has a solid background in computational astrophysics, strong track record in software development, and keen interest in dynamics of stellar systems. A key task is to lead the development and support applications of our pioneering code for orbital modelling of stellar systems, publicly released under the name DYNAMITE.
Your future tasks
* You lead the software development and support research applications of the orbital modeling code DYNAMITE.
* You contribute software expertise to other computational astrophysical projects.
* You contribute to publications in peer-reviewed journals and to (re)presentations at international meetings.
* You (co-)supervise Bachelor, Master and Doctoral students in Astronomy.
* You teach within the provisions of the collective bargaining agreement.
* You take on administrative tasks in research and teaching.
* You become an engaged member of the Dynamics of Stellar Systems research group and the Department of Astrophysics.
Your profile
* You must hold a Doctoral/PhD degree in astronomy/astrophysics with affinity for programming, or in computer science/applied mathematics with affinity for astronomy/astrophysics.
* You can demonstrate excellent abilities to work in a team and excellent communication skills in English.
* You possess excellent programming skills; within the DYNAMITE code, the combination of computationally intensive dynamical models and stellar population models applied to state-of-the-art spectroscopy requires novel optimisation algorithms and efficient programming.
* You can show a proven track record in object-oriented programming as necessary in larger software development teams.
* You are capable of scientific programming in Python.
* You have experience with supercomputing clusters and are well-versed in shell scripting.
* You had exposure to cloud-based platforms like GitHub.
Additionally
* Main-author publications in renowned subject-relevant media are a strong plus.
* Very good organizational skills are highly desirable.
* Knowledge of parallel computing and use of GPUs are desirable.
* Supervision and teaching experience is an advantage.
* Expertise in dynamical modelling and stellar spectroscopy are assets.
* Presentation experience in an international setting is a benefit.
