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, and is a hosting member of the PRACE European distributed supercomputing infrastructure. 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 770 staff from 55 countries.

Context And Mission

Within the Barcelona Supercomputing Center the Earth Sciences Department, led by Prof Francisco Doblas-Reyes, aims to deliver novel, advanced, and well-evaluated high-resolution global climate models capable of simulating and predicting climate estimations with unprecedented reliability. The successful candidate will be part of the Performance Team, a sub-group in the section of Computational Earth Sciences.

This team, composed of 10 members but steadily growing, performs R&D tasks in the field of Earth Science Model (ESM) performance: its goal is to identify models bottlenecks, research how to remove them and develop efficient code. The team has at its disposal cutting-edge performance tools, able to evaluate and represent different performance metrics. Possible solutions can go from using more efficient numerical algorithms to modifying the way the model exploits the HPC infrastructure.

The candidate will work on developing, porting and testing models, supporting scripts and libraries for European state-of-the-art NWP and climate models, by supporting the development of new versions of the BSC-ES models and working in the integration of new functionalities such as new coupling functionalities. These models will be scaled and executed in production in the upcoming EuroHPC Pre Exascale systems.

Key Duties

  • Contribute to the porting and testing of state-of-the-art parallel Earth models in Pre-Exascale systems.
  • Introduce new delopments needed to run the parallel Earth models in Pre-Exascale machines, such as new integrations for coupling different components.
  • Contribute to the development and maintainance of the software stack and scripts to execute Earth models on state-of-the-art HPCs.
  • Collaborate with the team in an Agile framework and attend project meetings with members of the department and other institutions for the project interest.


  • Education
    • Having a Bachelor in Computer Science, Telecommunications, Physics or related discipline.
    • Having a Master’s degree will be valued.
  • Essential Knowledge and Professional Experience
    • Good development skills and experience with UNIX/LINUX environments.
    • Excellent computing skills in high-level computer languages (especially FORTRAN or C/C++).
    • Understanding of HPC computer architecture issues including CPU, accelerators, memory, interconnect, parallel I/O, and computational performance
    • Knowledge of development and execution of scientific applications on parallel computers.
  • Additional Knowledge and Professional Experience
    • Experience of version control in a collaborative environment, including Git or SVN.
    • Experience in Python programming and/or scripting languages (Bash).
    • Previous experience in a scientific area related to the research position will be appreciated
  • Competences
    • Earth system models are sophisticated tools and High Performance Computers are complex systems. The candidate needs to have excellent problem-solving skills and a proactive attitude to address new challenges and perfect the current solutions so they gain reliability and efficiency.
    • This is a specialized position so the successful candidate is expected to have a demonstrated learning capacity and the motivation to maintain a learning progression during the contract.
    • The BSC Earth Sciences department is an international and interdisciplinary environment, so the candidate must be fluent in English and have good written and verbal skills.
    • The candidate will work for an international collaborative project, so it is mandatory to be able to fulfill schedules and coordinate with members from other institutions, as well as disseminate the advances in international workshops.


  • The position will be located at BSC within the Earth Sciences Department
  • We offer a full-time contract, a good working environment, a highly stimulating environment with state-of-the-art infrastructure, flexible working hours, extensive training plan, tickets restaurant, private health insurance, fully support to the relocation procedures
  • Duration: Temporary - 2 years renewable
  • Salary: we offer a competitive salary commensurate with the qualifications and experience of the candidate and according to the cost of living in Barcelona
  • Starting date: July 2022

Applications procedure and process

All applications must be made through BSC website and contain:

  • A full CV in English including contact details
