Hpc Engineer for Earth Sciences Applications

**Job Reference**: - 340_25_ES_CES_RE1 **Position**: **Closing Date**: - Friday, 30 May, 2025 **Reference**: 340_25_ES_CES_RE1 **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. Look at the BSC experience: BSC-CNS YouTube Channel Let's stay connected with BSC Folks 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. **Context And Mission** This team, composed of 18 members but steadily growing, performs R&D tasks in the field of Earth system model (ESM) performance. The team has at its disposal cutting-edge performance tools, able to evaluate and represent different performance metrics. Having identified those areas in the code, the experts in the team proceed to modify them without impacting the final results. Possible solutions can go from using more efficient numerical algorithms to modifying the way the model exploits the HPC infrastructure. **Key Duties** - They will be in charge of the deployment of the model on different EuroHPC machines. This will imply performing scalability studies, and implementing small computational optimizations if needed to ensure the optimal setup specific to each HPC platform. - Contribute to the develpment and improvement of the Auto-lb tool, used to improve the load balancing of the components in a coupled ESM, such as EC-Earth. - This position involves close interaction with the Climate Variability and Change (CVC) and Atmospheric Composition (AC) groups. **Requirements**: - Education - Having a Master’s degree in Computer Science, Engineering, Mathematics, Physics or related discipline - Essential Knowledge and Professional Experience - Excellent computing skills in high-level computer languages (especially Fortran or C/C++) and experience with Unix/Linux environments and scripting languages (Bash, Python, etc) - Programming skills to manage big and collaborative projects and experience with git and/or SVN - Experience or knowledge in HPC architecture and parallel programming - Experience or knowledge in running and optimizing scientific codes on large HPC systems. - Experience or knowledge in the usage and support of Unix - or Linux-based HPC systems - Experience in coupling peformance of Earth system models - Experience in profiling tools such as Extrae and Paraver will be valued - Competences - Excellent problem-solving skills - Proactive attitude - Learning capacity and motivation to maintain a learning progression - Good written and verbal skills and capacity to support Earth and Computational scientists - Fluency in English **Conditions** - The position will be located at BSC within the Earth Sciences Department - We offer a full-time contract (37.5h/week), a good working environment, a highly stimulating environment with state-of-the-art infrastructure, flexible working hours, extensive training plan, restaurant tickets, private health insurance, support to the relocation procedures - Duration: Open-ended contract due to technical and scientific activities linked to the project and budget duration - Holidays: 23 paid vacation days plus 24th and 31st of December per our collective agreement - Starting date: asap **Applications procedure and process** - A full CV in English including contact details - A cover/motivation letter with a statement of interest in English, clearly specifying for which specific area and topics the applicant wishes to be considered. Additionally, two references for further contacts must be included. Applications without this document will not be considered. **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_**: The recruitment panel will be composed of at least three people, ensuring at least 25% representation of women. The panel will make a final decision, and all individuals who participated in the interview phase will receive feedback with details on the accepta
