Job Description

Job tasks
The University of Basel is the oldest university in Switzerland, it counts over 12\'000 students and 4\'300 researchers in 7 faculties active in domains from humanities, economy to natural sciences. sciCORE is the center for scientific computing at the University of Basel and one of the technological platform of SIB - Swiss Institute of Bioinformatics. The main mission of sciCORE is to support scientists at the University of Basel and associated institutes in research domains with high computational demands. Current projects range from life sciences and medicine to physics, chemistry, economy and humanities.
\The sciCORE team operates a large-scale scientific HPC environment consisting of a Linux cluster with ~8000 cores (including GPUs), ~5 PB storage (IBM Spectrum Scale, BeeGFS), virtualization environments (XenServer) for internal management and hosting of web-accessible scientific services (e.g. SWISS-MODEL, SwissRegulon, ...).
\sciCORE is one of the infrastructure nodes of a national network coordinated by SIB - Swiss Institute of Bioinformatics to support biomedical-research projects, such as the Swiss Personalized Health Network (SPHN). Data protection, security and access controls are thus of high importance in our service.

  • Maintain the core set of web services offered by sciCORE (git, RStudio/Shiny, Atlassian suite, data management systems, service management systems, database servers, ...)
  • Support research groups offering scientific services as web-based applications (design support, configuration and deployment of VMs adapted to the application)
  • Collaborate to the implementation of security measures and services in our biomedical IT research environment (including logging and monitoring)
\- Participate in relevant technical meetings with our partners at University of Basel and at SIB - Swiss Institute of Bioinformatics
