HPC Linux System Administrator (100%)

The University of Basel is ranked among the best universities in the world due to its research

achievements and as the oldest university in Switzerland, can look back on over 550 years of successful history. It counts over 12'000 students and 4'300 researchers in 7 faculties active in domains from humanities and social sciences to natural sciences, with a clear focus on life sciences and medicine.

Research at university is increasingly data-driven and thus requires state-of-the-art services to support data-science applications, often with transdisciplinary approaches.

sciCORE is the center for scientific computing offering the infrastructure and expertise to facilitate data-driven research.

The sciCORE systems team (6 system specialists) operates a large-scale scientific HPC environment consisting of a Linux cluster with 15'000 cores (and about 70 GPUs), 12 PB storage (GPFS), virtualization environments (ProxMox, OpenStack) for internal management, user applications and hosting of web-accessible scientific services.

About 300 research groups benefit from our support with main domains of application in life science, biomedicine, physics, chemistry, and economy.

In addition, sciCORE is one of the infrastructure nodes of the national initiatives BioMedIT and Swiss Personalized Health Network, providing a safe environment for research based on patient data.

Data protection, security, access controls, and the associated work ethics are thus of high importance in our service.

If you are interested in getting on board, sciCORE is looking for an HPC Linux system administrator (100%).

With the support of our team, our new collaborator will :

Help our diverse community of scientists in using our computing infrastructure and collaborate within the team to guarantee smooth operations of the environment.
