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

We are seeking candidates with strong expertise in compiler development and code optimization to join the High-Performance Artifical Intelligence team at BSC.

Compiler frameworks are at the heart of modern AI inference — from data centers to edge devices, automotive, and robotics.

As AI models grow in complexity, the compilers that execute them must deliver leading performance, fast build times, and reduced memory footprints, across both Ahead-of-Time and Just-in-Time compilation targets. This role sits at that frontier.

You'll help shape the future of AI computing through compiler technology that is fast, flexible, and built for real-world models.

Key Duties

• Analyzing deep learning networks and developing novel compiler optimization algorithms.
• Designing and implementing advanced optimization passes using tools such as LLVM, MLIR, and Triton.
• Creating new programming abstractions that simplify how AI workloads are expressed and executed.
• Collaborating across hardware architecture, ML research, and domain science teams.
  
  

Requirements

• Education
• Computer Science Degree
• Essential Knowledge and Professional Experience
• Strong foundations in compiler design: IR representation, optimization passes, code generation pipelines
• Understanding of deep learning frameworks
• Additional Knowledge and Professional Experience
• Strong foundations in compiler design: IR representation, optimization passes, code generation pipelines
• Hands-on experience with LLVM and/or MLIR
• Proficiency in C++

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.

At BSC, we seek continuous improvement in our recruitment processes. For any suggestions or comments/complaints about our recruitment processes, please contact recruitment@bsc.es.
