In the framework of the Earth-Sciences department, the candidate will substantially improve the efficiency and productivity of numerical weather and climate simulations on high-performance computing platforms by supporting the end-to-end workflows of global Earth system modeling in HPC environments.
This will be obtained by improving and supporting: the development and operation of modeling workflows on state-of-the-art supercomputer systems, and the usability of these models and tools throughout the European HPC ecosystem.
The candidate will develop solutions for cross-cutting HPC challenges, in particular in the weather and climate domain, and help to develop existing workflow orchestration software.
Key Duties
Join the Autosubmit development team and work on improvements for the Autosubmit workflow engine.
Contribute to the refactoring of the Autosubmit code towards a more modular, efficient, and maintainable solution that maximizes test coverage.
Maintain the operational deployment on different HPC platforms.
Contribute to the Autosubmit development strategy by analyzing the user needs and learning from the benefits and disadvantages of the most used workflow tools in the Earth Sciences domain.
Support the users inside and outside the BSC center by adding new features to the existing and new tools.
Facilitate the adoption of the solutions developed through workshops and seminars in and out of the department.
Maintain the software in Git and deploy it to the HPC module and to the PyPi repository, publishing both source code updates and documentation.
