Chemical Safety Engineer; HSE-OHS-GI--LD

At CERN, the European Organization 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.

As a Chemical Safety Engineer you will join the HSE department, which supports CERN in the implementation and application of its Safety Policy. With the HSE department you will join the OHS Group, which is in charge of providing advice, monitoring, and following up on the implementation and accomplishment of safety objectives, aimed at a continuous improvement of a safe working environment.

Within this group you will join the General Safety and Equipment Integrity (GI) section. You will be one of the CERN specialists for Chemical Safety, joining a multidisciplinary team of Safety experts.
