What you'll do
The SY-STI-BDE Section oversees the conceptual design, construction, operation, and maintenance of beam-intercepting devices across the CERN's accelerator complex. The beam intercepting devices are precision mechanical equipment working in harsh environments that must be very reliable to guarantee the operation of CERN accelerators.
Are you passionate about mechanical engineering and skilled at multitasking? Join us and become part of a multidisciplinary team responsible for the design, assembly, installation, and maintenance of beam-intercepting devices. You will support safety-critical systems and an efficient operation of CERN's accelerators.
