Context And Mission The Language Modeling Team at the AI Institute hosted at BSC has consolidated experience across several core NLP and AI areas, including massive language model training, fine-tuning, post-training alignment, domain adaptation, AI agent development and unsupervised learning, including low-resource languages.
It has been entrusted by the Spanish and Catalan governments with the mission to develop foundational open-source resources and technologies for Spanish, Catalan and other co-official languages.
In addition, the team actively participates in various EU-funded international research initiatives.
In this context, the AI Institute is looking for talent to help advance its operations, research capabilities and technical infrastructure.The Language Modeling Team is seeking candidates with a strong background in computational linguistics and hands-on experience in Language Technologies; particularly in deep learning, large language model development, instruction tuning, and agentic workflows,



as well as related areas of Natural Language and Speech Processing.The successful candidate will work in a highly sophisticated HPC environment, access state-of-the-art computational infrastructure, and collaborate with leading experts both locally and internationally.
The researcher will be responsible for designing and implementing innovative techniques for language modeling, evaluation and system adaptation tailored to high-performance computing systems.
Key Duties Implement and test agentic workflows including multi-step reasoning and tool-use capabilities under the supervision of the senior architect.
Develop and refine Function Calling interfaces and connectors using the Model Context Protocol (MCP) to enhance model interactivity.
Execute post-training experiments using TRL, FastChat, and NeMo-RL to improve the agentic performance of small and large models.
Build and maintain evaluation pipelines specifically designed to measure the reliability and safety
