Job Description

Company Description
At , 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.

Introduction
Are you an experienced mechanical drafter with a talent for 3D design, ready to make an impact in an innovative engineering environment?
