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.

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 System Tools and Advanced Runtimes (STAR) group is a computer systems group that explores research across multiple layers of the system software stack, from operating systems, runtimes and low-level APIs to programming models, tools and applications. Our goal is to improve the system software stack to support increasingly complex workloads, including traditional HPC, AI and data analytics, on massively parallel HPC and cloud platforms.
The STAR group offers a postdoctoral position to work on operating systems, runtime systems, low-level system libraries and programming models for parallel applications. We are looking for a researcher with strong experience in systems software and an interest in advancing the interaction between operating systems, user-level runtimes and parallel programming frameworks.
The successful candidate will participate in European and industrial research projects, contributing to the design, implementation and evaluation of system-level mechanisms that improve the execution of parallel workloads. The position will also include opportunities to disseminate the work through top-tier conferences, workshops and journal publications.
We are looking for a motivated and talented researcher with strong C/C++ programming skills, experience in low-level systems software, and the ability to work on complex problems involving operating systems, runtimes, instrumentation and parallel programming models.
Key Duties
- Design, implement and evaluate extensions to operating systems, system libraries and runtime systems for parallel workloads
- Contribute to the development and maintenance of Task-Aware libraries and low-level APIs used by parallel applications and runtimes.
- Contribute to the integration of runtimes and system-level mechanisms with programming models such as OpenMP, OmpSs-2 and other parallel frameworks.
- Lead or coordinate technical tasks within European and industrial projects when required.
Requirements
- Education
- PhD in Computer Sciences, Computer Engineering, Telecommunication Engineering or equivalent.
- Essential Knowledge and Professional Experience
- Strong experience in operating systems, runtime systems, system libraries or low-level systems software.
- Excellent C/C++ programming skills.
- Experience with Linux systems programming, pthreads, threading libraries, scheduling mechanisms or low-level runtime support.
- Competences
- Ability to take the initiative, prioritize and work under set deadlines and pressure
- Ability to work independently and in a team
- Motivation to contribute to high-quality research software and publish results in competitive venues.

Applications procedure and process
All applications must be submitted via the BSC website and contain:
- 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
-
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 [at] bsc [dot] es.
