Job Description
Your responsibilities
Are you a hands-on mechanical engineer with a passion for cutting-edge technology and precision assemblies? If so, seize this opportunity to join CERN's Experimental Physics (EP) Department, where you will contribute to the development and construction of the next generation of particle detectors.
The CERN ATLAS Team plays a leading role in building the future silicon ATLAS Inner Tracker (ITk). In particular, the CERN team focuses on the development of the Pixel Outer Barrel (OB), including the design, prototyping, and assembly of support structures, as well as the final integration and testing of the detector.
As a Mechanical Engineer in the CERN ATLAS Team, your key responsibilities will include:
- Participating in the conception, detailed design, production, testing, and installation of detector components, assembly tooling, and test infrastructure for the ITk Pixel Outer Barrel.
- Developing, documenting, and implementing procedures for the assembly, testing, and repair of detector components and sub-assemblies.
- Managing the procurement of materials, detector components, and tooling, including follow-up on acceptance and installation.
- Contributing hands-on to the production and quality control of the OB local supports and global structures, supporting both the cell loading and integration activities at CERN.
Your profile
Skills:
- Proven experience in the design of precision mechanical components and systems.
- Demonstrated experience in the use of CAD software for 3D modelling (ideally CATIA V5), and in producing 2D technical drawings in accordance with relevant ISO standards for dimensioning and tolerancing.
- Hands-on experience in the assembly and testing of prototypes.
- A "can-do" attitude, and a willingness to take part directly in the assembly and testing of unique detector components.
- A rigorous and organised approach to work, delivering high-quality results from the outset.
- Ability to work effectively as part of a team.
- A flexible approach to work, with the ability to adapt quickly to changing priorities and requirements.
- The following skills would be considered an asset, but are not essential:
- A good understanding of tracking detector mechanics.
- Practical knowledge of adhesive bonding and composite materials.
- Experience using metrology equipment.
- Spoken and written English, with a commitment to learn French.
Eligibility criteria:
- You are a national of a CERN Member or Associate Member State.
- You have a professional background in Mechanical Engineering or equivalent (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 http://home.cern.
