Research Software Engineer

80%-100%, Lugano, permanent

The Swiss National Supercomputing Centre (CSCS) develops and operates cutting-edge, high-performance computing (HPC) systems as an essential service facility for science. The centre enables world-class research through its scientific user lab, which is available to domestic and international researchers in academia, industry, and the business sector. The centre is operated by ETH Zurich and has offices in Lugano (headquarters) and Zurich.

Project background

CSCS develops efficient software libraries and tools for scientific computing, specifically performance-portable C++ libraries for GPU-accelerated HPC architectures. These activities are carried out through close collaboration between application developers and domain scientists, who provide the requirements for further development and for integrating these libraries into established simulation packages.

Performance modelling and analysis are important for predicting performance on future systems. The broad range of application domains includes electronic structure theory, linear algebra, geophysics, and weather and climate.

To expand our team and capabilities, CSCS has an open position at one of our offices in Lugano or Zurich for a research software engineer specialised in applied mathematics.
