Job description

Mechanical Technician - Superconducting Magnets (TE-MSC-SMT-2025-34-LD)
Geneva, Switzerland
Contract
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 motivated by precision mechanics and interested in contributing to innovative magnet technology for particle accelerators? Join us in building the next generation of superconducting magnets at CERN.

The Magnets, Superconductors and Cryostats (MSC) group in the Technology Department (TE) is responsible for the design, construction, and testing of both superconducting and normal conducting magnets for CERN's accelerator complex. This includes magnet cryostat design, integration into accelerator systems, and quality control, and operational support for magnet performance and devices.

Within MSC, the Superconducting Magnet Technology (SMT) section is responsible for advancing high-field magnet technologies for future accelerators. These advanced systems use superconducting materials with complex mechanical and electrical properties, with complex mechanical and electrical properties, presenting significant manufacturing challenges. Addressing these challenges requires the development of innovative materials, processes, and tooling.

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 programming and machining operations on CNC machines (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're passionate about precision engineering and hands-on prototyping, this is your chance to take part in innovative projects at the forefront of accelerator technology.
