Electron Beam Welding Engineer (EN-MME-FW-2024-191-GRAE)

Job Description

Your responsibilities

The Engineering Department (EN) advances technological boundaries to deliver innovative research tools to the global physics and engineering community.

This position is open in the Mechanical and Materials Engineering (MME) Group , which possesses, maintains, and develops 40 years of expertise in the mechanical design, manufacturing, and assembly of accelerator and detector devices.

Within the MME group, the Forming & Welding (FW) section provides expertise in metal forming technologies and assembly processes, including electron and laser beam welding, arc welding, orbital welding, and vacuum brazing.

As an Electron Beam Welding (EBW) Engineer in the FW section, you will join a team of highly qualified technicians and engineers specializing in Electron Beam and Laser welding processes.

In this role, you will participate in EBW activities for the fabrication of prototypes and components for accelerators and related experimental facilities.

After an initial familiarization period and with the guidance of colleagues, you will :

• Perform welding operations on state-of-the-art EBW machines.
• Develop and optimize welding parameters to meet stringent specifications for ultra-high vacuum, cryogenics, pressure vessels, and radiofrequency applications.
• Design jigs and fixtures dedicated to EBW.
• Collaborate closely with customers, design offices, and manufacturing engineering facilities across CERN to improve welded designs for manufacturing.
• Prepare technical reports (e.g., Welding Procedure Specifications, assembly procedures) and present findings to project stakeholders.

In the longer term, you are encouraged to learn additional technologies, such as laser beam welding, to enhance team versatility.

About us

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.
