Electrical Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading scientific research organization established in 195

• It is known for its groundbreaking work in particle physics and operates the world's largest particle physics laboratory. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the globe, representing more than 100 nationalities. The organization is dedicated to advancing knowledge in fundamental physics and technology, and it operates in multiple countries, primarily in Europe, with its headquarters located in Geneva, Switzerland.

Job Overview:
As an Electrical Engineer at CERN, you will play a pivotal role in the upgrade of the CMS (Compact Muon Solenoid) detector's electrical infrastructure. This position requires you to work closely with the CERN electrical infrastructure team to refine project specifications, validate technical solutions, and coordinate the implementation of these solutions. You will supervise the power distribution cabling activities for the CMS sub-detectors and participate in safety assessments for all electrical activities, ensuring compliance with safety standards. Your role will involve overseeing the evolution of the electrical network in both surface and underground areas of the CMS, reporting on scheduling, work progress, and risks to the Technical coordination-team" style="border-bottom: 1px dotted #007bff !important;">Coordination team. You will also coordinate procurement and installation efforts for power systems and cables, establish quality assurance procedures, and support the CMS detector team in re-powering and preparing for operational readiness.

Duties and Responsibilities:

• Oversee the evolution of the electrical network in CMS surface and underground areas, acting as the interface to contractors and support groups.
• Report to Technical Coordination on scheduling, co-activity requirements, work progress, and risks.
• Coordinate procurement, connectorisation, and installation of power systems and cables for CMS sub-detectors.
• Establish QA/QC procedures for commissioning and acceptance of electrical installations, documenting test execution.
• Supervise site activities by contractors and collaboration personnel, ensuring proper documentation.
• Support the CMS detector team in re-powering and readiness for operation, ensuring all safety protocols are followed.
• Participate in safety assessments of electrical activities, including lock-down and re-powering of systems from low-voltage to high-voltage.

Required Qualifications:
Candidates must possess a Master's Degree or equivalent relevant experience in Electrical Engineering or a related field. Established experience in designing and sizing low-voltage power distribution systems is essential. Hands-on experience with installation, commissioning, and troubleshooting of complex power distribution systems is required. Proficiency in using electrical measurement and diagnostic instruments is necessary, along with a solid understanding of electrical schematics and cabling documentation. Candidates should be able to produce high-quality documentation using electrical design software and have knowledge of power distribution equipment and high-reliability connection principles. Experience in organizing teamwork and ensuring safety in multidisciplinary environments is also required.

Educational Background:
A Master's Degree in Electrical Engineering or a related field is required. Equivalent relevant experience may also be considered. Candidates should have a strong foundation in electrical engineering principles, particularly in power distribution systems.

Experience:
Candidates should have established experience in the design and sizing of low-voltage power distribution systems. Hands-on experience with the installation, commissioning, and troubleshooting of complex power distribution systems is essential. Experience in organizing teamwork and working within multidisciplinary teams is also required, along with a commitment to ensuring safety in the workplace.

Languages:
Fluency in spoken and written English or French is mandatory, with a commitment to learn the other language being highly desirable. Proficiency in both languages will enhance communication and collaboration within the diverse CERN community.

Additional Notes:
This position is a limited duration contract for 4 years, with the possibility of extension up to 8 years and eligibility for an indefinite contract tenure. The role requires working 40 hours per week, fully onsite, and may involve work in radiation areas, interventions in underground installations, and shift work as required. A valid driving license is necessary, and the selected candidate must obtain medical clearance due to occupational health risks associated with the position. The job grade is 6-7, and the reference for this position is EP-CMS-IC-2026-103-LD. CERN offers a competitive salary that is tax-free, along with 30 days of paid leave per year, comprehensive health insurance, family allowances, and a relocation package depending on individual circumstances.
