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.

Let's stay connected with BSC Folks!

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

The Language Modeling Team at the newly created AI Institute hosted at BSC has consolidated experience in several NLP areas, such as massive language model building, biomedical text mining, and unsupervised learning for under-resourced languages and domains. It has been entrusted by the Spanish and the Catalan governments with the mission to develop fundamental open- source resources and technologies for Spanish and Catalan. In connection with this, the LM team is currently in charge of two flagship projects at the national and regional level: the ALIA project, funded by the Spanish Secretariat of Digitalisation and Artificial Intelligence, and the AINA project, aimed at developing AI resources for Catalan, funded by the Catalan Digitalisation Department. In addition, the Unit participates in various EU funded international projects. In this context, the newly created AI Institute is looking for talent to help design and improve its operations and infrastructure.

The Language Modeling Team is looking for candidates with a background in computational linguistics with experience in Language Technologies, specifically in Deep Learning and large language model building, and possibly in other areas of Natural Language and Speech Processing.

The successful candidate will work in a highly sophisticated HPC environment, have access to state-of-the-art systems and computational infrastructures, and establish collaborations with experts in different areas at the local and international levels.

The researcher will implement innovative techniques for language modelling and evaluation in the HPC environment.

Key Duties

• Coordinate and lead the post-training team to drive the alignment and instruction-tuning strategy for massive language models.
• Ensure instructed LLMs are accessible and strictly optimized for specific downstream use cases.
• Develop and implement synthetic data generation pipelines designed to enhance model reasoning and instruction-following capabilities.
• Research and deploy comprehensive post-training strategies, including instruction processing, algorithm design, and the rigorous evaluation of instructed LLMs.
• Adapt alignment frameworks for deployment on MareNostrum 5.
  
  

Requirements

• Education
• Degree in Computer Science, Mathematics or related.
• Essential Knowledge and Professional Experience
• Advanced proficiency in Python, Linux, and Bash scripting.
• Extensive hands-on experience with AI frameworks for alignment, specifically PyTorch, DeepSpeed, Megatron, NeMo.
• Deep knowledge of HPC infrastructure and workload managers, specifically Slurm.
• Proven capability to engineer and execute deep learning pipelines in restricted HPC network environments.
• Additional Knowledge and Professional Experience
• Published research in the field of Natural Language Processing.

Development of the recruitment process

The selection will be carried out through a competitive examination system ("Concurso-Oposición"). The recruitment process consists of two phases:

• Curriculum Analysis: Evaluation of previous experience and/or scientific history, degree, training, and other professional information relevant to the position. - 40 points
• Interview phase: The highest-rated candidates at the curriculum level will be invited to the interview phase, conducted by the corresponding department and Human Resources. In this phase, technical competencies, knowledge, skills, and professional experience related to the position, as well as the required personal competencies, will be evaluated. - 60 points. A minimum of 30 points out of 60 must be obtained to be eligible for the position.
  
  

The recruitment panel will be composed of at least three people, ensuring at least 25% representation of women.

In accordance with OTM-R principles, a gender-balanced recruitment panel is formed for each vacancy at the beginning of the process. After reviewing the content of the applications, the panel will begin the interviews, with at least one technical and one administrative interview. At a minimum, a personality questionnaire as well as a technical exercise will be conducted during the process.

The panel will make a final decision, and all individuals who participated in the interview phase will receive feedback with details on the acceptance or rejection of their profile.
