AI Application Support Specialist for AI Factory

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.   Key Duties   Optimize and adapt scientific application codes to new pre-exascale architectures and systems, focusing in AI applications and technologies. Improve the performance of existing AI environments, improving the serial efficiency and the scalability, changing, if necessary, the code or helping the developers with their required modifications. Choose and adapt algorithms and/or library routines to improve applications to specific computer architectures (accelerators, new programming models, etc.). Provide consultancy to scientists on AI solutions that can improve the evolution of their research. Generate performance analysis and benchmarks for selected applications and report the results to the applications developers. Collaborate with other functional groups at European and International level on technical matters related to supporting AI scientific application work.    Requirements   Education A Bachelor's degree in Computer Science or a related discipline with a focus on Artificial Intelligence at a technical level is required.
