About BSCThe Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) is the leading supercomputing center in Spain. It houses MareNostrum, one of the most powerful supercomputers in Europe, was a founding and hosting member of the former European HPC infrastructure PRACE (Partnership for Advanced Computing in Europe), and is now hosting entity for EuroHPC JU, the Joint Undertaking that leads large-scale investments and HPC provision in Europe. The mission of BSC is to research, develop and manage information technologies in order to facilitate scientific progress. BSC combines HPC service provision and R&D; into both computer and computational science (life, earth and engineering sciences) under one roof, and currently has over staff from 60 countries. We are particularly interested for this role in the strengths and lived experiences of women and underrepresented groups to help us avoid perpetuating biases and oversights in science and IT research. In instances of equal merit, the incorporation of the under-represented sex will be favoured. We promote Equity, Diversity and Inclusion, fostering an environment where each and every one of us is appreciated for who we are, regardless of our differences. If you consider that you do not meet all the requirements, we encourage you to continue applying for the job offer. We value diversity of experiences and skills, and you could bring unique perspectives to our team.

Context And MissionThe successful candidate will join the Computational Earth Sciences group within the Earth Sciences department to contribute to projects within the Destination Earth (DestinE) initiative. DestinE is a European Union flagship programme building high-precision digital replicas 'Digital Twins' of the Earth system to support climate adaptation and extreme-weather preparedness. The candidate will work to develop AI-ready datasets and data pipelines that support the training and evaluation of regional AI weather and climate forecasting systems, built on open-source frameworks such as Anemoi. This includes curating and preparing high-resolution simulation and observational data, building reproducible pipelines to make these datasets machine-learning-ready, and supporting their deployment and validation on high-performance and AI-oriented computing infrastructure. The role involves close collaboration with an international consortium of European meteorological and research institutions.

Key Duties





Curate and assess regional analyses, forecasts, and reanalyses for training and evaluating the regional AI forecasting system

Design, build, and maintain reproducible ML data pipelines that transform raw simulation and observational data into Anemoi-compatible datasets

Implement automated testing and CI/CD pipelines for the data-processing workflows

Support deployment and validation of data pipelines on HPC and AI Factory infrastructure, including scalability and performance testing

Collaborate with the international consortium and document pipelines to ensure reproducibility and traceability

RequirementsEducationBachelor's degree in Computer Science, Physics, Environmental/Atmospheric Science, or a related discipline. A Master's degree or PhD in a relevant field will be highly valued.

Essential Knowledge and Professional Experience

Experience handling scientific data formats such as NetCDF, GRIB, Zarr, and tools such as Xarray, CDO/NCO

Experience preparing datasets for machine-learning training pipelines, ideally in Earth, weather, or climate sciences

Familiarity with UNIX/Linux environments and scripting languages

Experience with high-performance computing (HPC) environments, including job schedulers (e.g. Slurm) and GPU-based workflows

Additional Knowledge and Professional Experience

Familiarity with the Anemoi ecosystem (anemoi-datasets, anemoi-training) or similar ML-ready NWP dataset frameworks will be highly valued.

Knowledge of NWP/reanalysis datasets (e.g. ERA5, CERRA, regional model output) and data-quality assessment.

Experience with CI/CD tools, containerization (Docker/Podman) and automated testing.

Experience with version control systems like Git.

Fluency in English is essential.

Proficiency in Spanish and other European languages would be advantageous.

Competences

Ability to work independently and within an international, multi-partner consortium to achieve project goals.

Strong problem-solving skills and attention to detail.

Excellent communication skills to collaborate effectively with interdisciplinary teams.
