Jobbeschreibung

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.

Your responsibilities

• Participate in the purchase, storage and shipment of raw material and components.
• Handle the conditioning of several components to be compliant with the Ultra-High Vacuum (UHV) requirements of collimators.
• Perform the machining of simple parts based on drawings produced with CAD programs.
• Be active on the assembly of collimators and several sub-components and its auxiliary systems.
• Participate in the assembly of the HL-LHC beam dump systems.
• Keep track and maintain all related documents and databases.
• Take an active role in the installation, commissioning and maintenance of the equipment.
• Manage the appropriate disposal/storage of radioactive parts and equipment withdrawn from the facility.
• Provide mechanical and logistics support.
• Contribute to mechanical support activities around different facilities at CERN.

Your profile

• Assembling and testing precision mechanics.

Skills

• Knowledge of CAD systems, 3D and 2D drawing.
• Good communication.
• Well-organised.
• Accountability.
• Working in a team, as well as independently
• Spoken and written English or French, with a commitment to learn the other language.

Eligibility criteria

• You are a national of a CERN Member or Associate Member State.
• By the application deadline, you have a maximum of two years of professional experience since graduation in Mechanical Engineering (or a related field) and your highest educational qualification is a general secondary education diploma.
• You have never had a CERN fellow or graduate contract before.
• Applicants with a Bachelor's, Master's or PhD degree are not eligible.
