Application deadline: 31 October 2020

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.

Key Duties

Be the main responsible for the EC-Earth model department infrastructure. In practice, this involves developing and maintaining the supporting software stack and workflow additions, taking care of the project repository and supporting the scientific developments. Regularly execute and validate the cyclic testing suite. Improve the testing software allowing to perform these tests in a pseudo-automatic fashion. Support scientific experiments by helping the department users, addressing arising technical issues and communicating further necessities to the rest of the team, developers of the underlying software stack. Collaborate with members of the department and other institutions in the improvement of the system. Communicate the advances and progresses in department events such as training and tutorials or international workshops.

Experience of Python programming and/or scripting languages (Bash). Previous experience in scientific Python packages (Python Numpy, Scipy, ...) will be valued. Previous experience in a scientific area related to the research position will be appreciated. Competences Earth system models are sophisticated tools and High-Performance Computers are complex systems. The candidate needs to have excellent problem-solving skills and a proactive attitude to address new challenges and perfect the current solutions so they gain in reliability and efficiency. This is a specialised position so the successful candidate is expected to have a demonstrated learning capacity and the motivation to maintain a learning progression during the contract. The BSC Earth Sciences department is an international and interdisciplinary environment, so the candidate must be fluent in English and have good written and verbal skills and the capacity to support Earth and Computational scientists. EC-Earth is a collaborative project, so it is mandatory to be able to fulfil schedules and coordinate with members from other institutions, as well as to disseminate the advances in international workshops.
