Job Description

Your responsibilities

We are seeking a motivated Project Engineer to oversee major infrastructure upgrade projects within the CMS Experimental area. In this role, you will act as the project coordinator, organising and supervising various stakeholders including CERN engineering teams and external contractors to ensure projects are delivered on time, within budget, and meet the required specifications. Your key responsibilities will include:

• Finalising Surface Facilities: You will coordinate the surface facilities for the CMS ECAL and HGCAL Phase 2 upgrade projects. This involves managing the installation of essential services such as electrical systems, civil engineering works, cooling and ventilation.
• Underground Upgrades: Working alongside a senior CERN staff member, you will help coordinate Phase 2 upgrades in the underground CMS service cavern, including the installation of new CO2 cooling plants.

In addition to these project management duties, you will provide engineering support by creating detailed layouts and 3D drawings for other CMS infrastructure projects. This position offers an excellent opportunity for an early career professional to gain hands-on experience managing complex engineering projects while contributing to high-profile initiatives. If you are proactive, eager to develop your skills, and passionate about engineering, we would love to hear from you.

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.
