Mechanical Engineer (EP-CMX-EC-2024-126-GRAE)

Your responsibilities

You will join a team of engineers to work on the design and construction of the CMS High Granularity Calorimeter (HGCAL) detectors (one for each end of CMS). Fully assembled each detector weighs around 220 tons and reaches a diameter of up to 5 m. The whole structure, made of a combination of stainless steel, copper, lead, silicon and scintillator along with all the cabling and services, is kept at -35C with a sophisticated CO2-based cooling system.

Your activities will be during a crucial phase of the detector development, with its installation in the CMS experiment foreseen in 2027. You will be involved in several engineering activities for the final design, production/procurement, testing and installation of the HGCAL.

In particular you will:

• Perform structural and thermal calculations (using Ansys)
• Design mechanical pieces (normally using Catia)
• Setup and perform tests to validate technical choices
• Write technical specifications; -setup tenders and follow-up industrial contracts.

You will also take part in the final detector assembly and installation.

Your profile

Skills and/or knowledge

• Master heat transfer and static structural calculations.
• Be very familiar with numerical mechanics and software analysis tools, preferably with Ansys.
• Familiarity with engineering design using CAD software (CATIA in particular).
• Knowledge of instrumentation hardware and data taking/analysis would be an asset.
• 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.
• 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.

Job closing date: August 13 at 23:59 hrs CEST.

Job reference: EP-CMX-EC-2024-126-GRAE

Contract duration: 24 months, with a possible extension up to 36 months maximum.

Target start date: 01-October-2024

This position requires:

• Interventions in underground installations.
• Residence in the immediate vicinity of the Organization's installations.
• A valid driving licence.

What we offer

• A monthly stipend ranging between 5134 and 5647 Swiss Francs (net of tax).
• Coverage by CERN's comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
• Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract.
• 30 days of paid leave per year.
• On-the-job and formal training at CERN as well as in-house language courses for English and/or French.

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.
