Company Description

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.

Job Description

Introduction

Are you ready to push the boundaries of superconducting magnet technology and contribute to the future of particle accelerators?

The Magnets, Superconductors and Cryostats (MSC) group of the Technology Department (TE), has the mandate to design, construct, and measure the superconducting and normal conducting magnets for the CERN accelerator complex; integrate them in the CERN accelerator complex; design the magnet cryostats and perform the magnet quality control. The group also provides support to the operation of the accelerators for magnets, magnet performance and devices.

The Superconducting Magnets Technology (MSC-SMT) section is responsible for advancing high-field magnet technologies for future accelerators. This requires the use of superconducting materials, whose unique electrical and mechanical properties present significant manufacturing challenges, demanding innovative materials, processes, and tools.

Functions

As a Mechanical Technician, you will be part of a dedicated team focused on designing, developing, and prototyping small-scale models of CERN’s next-generation superconducting magnets. This is an exciting opportunity to contribute to cutting-edge accelerator technology and push the boundaries of precision engineering.

Your main responsibilities will include:

• Mechanical Workshop and Contractor Coordination: Managing the mechanical workshop, performing machining operations (e.g., milling, turning on a lathe), coordinating a small team of mechanical technicians, and liaising with internal workshops for subcontracting parts as needed;
• Manufacturing and Assembly: Machining and assembling high-precision mechanical components;
• Prototype Development: Contributing to the design and validation of components, tooling, and assembly processes for model magnet construction. This includes refining components and tooling, using Computer-Aided Design (CAD) software.

If you are passionate about precision engineering and hands-on prototyping, this is your chance to take part in innovative projects at the forefront of accelerator technology.
