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.

Your profile

Skills

Required:

• Knowledge/experience in Electron Beam Welding or Laser Beam technologies;
• Knowledge/experience in mechanics and use of CAD / CAM software, including ISO G-code;
• Hands-on experience with CNC machines such as milling/turning machines, sheet metal machinery;
• Ability to read/interpret technical drawings and ISO tolerancing (dimensional and geometrical product specification standards) and the ability of drafting technical drawings;
• Organised and self-motivated, and able to carry out tasks autonomously when required;
• Fluent in English or French.

Advantageous:

• Knowledge of welding metallurgy;
• Experience of high-precision mechanical engineering;
• Understanding of main international standards related to beam welding.

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 either a Bachelor’s or Master’s degree.
• You have never had a CERN fellow or graduate contract before.
• Applicants without University degree are not eligible.
• Applicants with a PhD are not eligible.

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. Find out more on http://home.cern.

Diversity has been an integral part of CERN’s mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
