Job Description

Your responsibilities

Are you passionate about fabrication using state-of-the-art technologies, and with a focus on sustainable actions? Are you skilled in both manufacturing techniques and mechanical design? Then this is an opportunity for you: you will be part of a multidisciplinary team creating a large variety of equipment and components used at CERN, in the framework of a wide range of research and development projects. CERN, take part!

The Engineering Department (EN) pushes forward the limits of technology to provide innovative research tools to the physics and engineering worldwide community. The position is opened in the Mechanical and Materials Engineering (MME) Group, which owns, maintains and develops the 40 years old know-how on the mechanical design, manufacturing and assembly of accelerator and detector devices.

As a Mechanical Fabrication and Sustainability Engineer in the MME Group, Machining and Maintenance Section (MME-MA), you will participate in:

  • Ongoing and new projects within MME and CERN, related towards better sustainability in design and production of mechanical components
  • Understanding and evaluating the impact of the different fabrication technologies being implemented in manufacturing of mechanical components for accelerators
  • Conceiving and establishing guidelines for enhanced manufacturing, in terms of sustainability and also in view of the full lifecycle of components designed and produced by MME.

You will also participate in the follow-up of fabrication projects. The activities will focus on the construction of mechanical systems for radiofrequency and for related auxiliary systems, for CERN ongoing and future projects. Production will rely on the wide range of technologies, such as state-of-art machining, but also forming and welding, performed in one of the Group's workshops and in collaboration with Industry.

Your profile

Skills and/or knowledge

Required fabrication skills/knowledge:

  • Experience with 3D and 2D technical drawings: ability to read/interpret technical drawings and ISO GPS tolerancing (dimensional and geometrical product specification standards)
  • Knowledge and experience in application of mechanical fabrication methods
  • Knowledge of metallic and non-metallic materials
  • Initial experience in mechanical components assembly, good understanding of fabrication techniques and their application to the design process

Required sustainability skills/knowledge:

  • Knowledge of lifecycle assessment techniques would be a strong asset
  • Knowledge on sustainability evaluation strategy for fabrication would be a strong asset

Valuable skills/knowledge:

  • Experience with CAD tools (preferably CATIA) would be an asset
  • Knowledge of mechanical fabrication in the following domains would be an asset: pressure vessels, vacuum chambers, cryogenics.
  • Fluent in English, the ability to work in French would be an advantage.

Eligibility criteria:

  • You are a national of a CERN Member or Associate Member State.
  • You have a professional background in Mechanical Engineering (or a related field) and have either:
    • a Master's degree with 2 to 6 years of post-graduation professional experience;
    • or a PhD with no more than 3 years of post-graduation professional experience.
  • You have never had a CERN fellow or graduate contract before.

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

We are on a Quest. A Journey into discovery like no other. Bring your expertise to our unique work and develop your knowledge and skills at pace. Join world-class subject matter experts on unique projects, in a Quest for greater knowledge and deeper understanding.
