Job description

Context And Mission

Within the Computational Earth Sciences group, the successful candidate will be part of the Models and Workflows team, being in charge of improving and maintaining the existing software stack that is used to manage and monitor scientific experiments in different High-Performance Computing facilities, as well as providing support to the scientific groups of the Earth Sciences department.

The Models and Workflows team devotes to the research and development of methodologies and tools essential to efficiently use the variety of computing resources available at the BSC and in other HPC institutions. The team is composed of 11 members and has strong connections with the Performance and Data teams, as well as with the scientific groups.

The candidate will work within the EC-Earth climate model ecosystem, which is developed and maintained by various institutions in Europe, including the BSC. EC-Earth3 is an established model with a solid in-house supporting software stack, which is developed following a Continuous Delivery strategy supported by cyclic pseudo-automatic testing. EC-Earth4 is the upcoming model cycle that will bring structural changes with important involvement of the BSC. This model will run on state of the art systems such as the upcoming EuroHPC Pre Exascale systems.
