HPC Performance 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 is leading an effort to develop scientific software and libraries for HPC platforms supporting complex workflows that simplify access to computing resources. To support this, we develop performance-portable applications and libraries able to run efficiently on a large range of hardware platforms.

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 specialized in HPC performance engineering.

Job description

You will support the greater CSCS HPC community across a variety of scientific domains by helping  to develop optimal workflows for applications and related scientific libraries on HPC platforms. 

Your responsabilities:

  • Benchmark existing codes to identify the potential performance improvements and implement specific optimizations for different hardware environments;
  • Design the interfaces of libraries and applications to enable their further optimization in current and future computer architectures;
  • Contribute to the development of performance measurement and analysis tools to support your work and the work of others.

Your profile

You should have a sound knowledge of modern software engineering skills, such as computer science, computer architectures, and code optimization.

Expected qualifications:

  • Knowledge of optimization techniques such as exploiting data locality and instruction-level parallelism;
  • Node-level parallelism, multi-threading, or GPU acceleration;
  • Distributed memory applications using MPI;
  • Test-driven design and other software engineering methodologies, especially in the context of HPC.

You should have a bachelor’s degree in computer science, mathematics, or natural sciences, preferably with a master’s, Ph.D., or relevant industry experience.
