Company Description
At CERN, the European Organisation for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.
Job Description
IT’s Compute and Devices Group is looking for a computing engineer to take over responsibility for the onsite High-Performance Compute (HPC) SLURM clusters which have established use cases in the Organisation including for the ATS sector and the Theory department.
