About BSC

The 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 1000 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 Mission

Supercomputers are essential for tackling the most challenging and complex scientific and technological problems. Beyond simulations, they now enable the use of neural networks and large language models to address engineering challenges, empowering companies to achieve their goals through AI technologies. This position will be part of the Operations Department within the User Support team. The team will focus on supporting AI applications for key projects utilizing BSC resources, including performance optimization, code porting, specialized AI tutoring, and enhancing the scalability and performance of models.

BSC hosts one of the largest and most advanced supercomputers in Europe within the framework of EUROHPC-JU. The pre-exascale system MareNostrum 5 (MN5) delivers a sustained performance of 205 PFlops, with over 180 PFlops powered by NVIDIA H100 GPUs, making it one of the world’s leading AI and HPC infrastructures. MN5 represents a key technological pillar for Europe’s digital sovereignty, enabling groundbreaking research in artificial intelligence, data analytics, and scientific computing.

A major innovation of the system is the MN5-AI partition, specifically designed to accelerate AI research and industrial innovation. This partition plays a central role in the AI Factories initiative, which aims to strengthen the European AI ecosystem by providing large-scale computational resources for training and deploying advanced AI models. Through MN5-AI, BSC contributes directly to building a federated network of AI supercomputing centers in Europe, fostering collaboration between academia, industry, and public institutions to advance trustworthy and high-performance AI technologies.

The HPC User Support team is therefore crucial in optimizing the use of MN5 and MN5-AI, ensuring that users can fully exploit these resources for their AI and HPC workloads. The team assists key projects with daily operations, helping researchers and companies push the boundaries of what is computationally possible.
