1-2 positions as Research Software Engineer (RSE) are available at the Institute of Theoretical Astrophysics. The position as Research Software Engineer is connected to the Rosseland Centre for Solar Physics (RoCS) funded by the Research Council of Norway and the University of Oslo from November 1st, 2017.

The primary goal of RoCS 10-year effort lies in understanding the workings of the energetic Sun. To attack this goal a concerted effort of numerical modelling, both fluid (extended MHD) and particle oriented, will be combined with high quality observations taken at ground based and space-based observatories to produce models of the active Sun. The Solar group at the ITA is led by Mats Carlsson, who is also the leader of RoCS.

The group has an internationally leading competence in radiative transfer and radiative hydrodynamics. Observationally, the group has access to the Swedish 1-meter Solar Telescope on La Palma, to ALMA, to several space-based satellites such as NASA’s IRIS and SDO, JAXA’s Hinode and in the near future ESA’s Solar Orbiter. The group makes extensive use of local and national High-Performance Computing facilities. A large coding effort is underway with the goal of developing exascale-ready codes that can scale to more than a million threads.

A successful candidate will provide software engineering expertise, support and training to RoCS researchers. The RSE will promote the use of best practices at all stages of the research software development cycle and ensure the sustainable development of scientific software. In addition, the RSA will help the solar physics research group with running simulation codes, both the Bifrost radiation MHD code and radiative transfer post-processing codes (RH, MULTI3D) ), post-processing of observational data,  and assist in the analysis of the data.

Qualification requirements

This position requires

  • Relevant higher education (e.g. Physics/Astrophysics/Computer Science) at a MSc level.
