Electrical Engineer for Safety Systems (EN-AA-CSE-2026-112-GRAP)

Job Description

As an Electrical Engineer, you will join the Engineering Department (EN), specifically the EN-AA-CSE team, to work on the Future Circular Collider (FCC) study.

The FCC Feasibility Study investigated the technical and financial viability of the FCC at CERN.

By looking at the geological and environmental conditions, as well as technically feasible concepts for infrastructures, civil engineering, and detectors, the FCC study enters a reference design phase where concepts are refined for rapid transition to civil engineering procurement.

The CERN Access and Alarms group (EN-AA) is tasked to contribute to the analysis and design of the necessary fire safety systems in this new facility.

It will be housed in a new underground circular tunnel with a circumference of 90.7 km, access shaft depths between 180 and 400 m, eight surface sites and four experiments.

• Your Responsibilities
• Carrying out fire risk analysis in collaboration with safety experts and members of the study team.
• Identification of possible solutions, both off‑the‑shelf and custom, to reduce the fire risk to an acceptable level.
• Identification of needs for fire safety systems and of their high‑level requirements.
• Design engineering – high‑level design of electrical safety systems and cabling/powering requirements.
• Preparation of technical studies, cost estimations, project documents, and review of documents prepared by other participating groups and contractors.
• Development of quality plans and documents.
• Follow up on schedule, including participation in the FCC Technical Infrastructure WG and FCC Safety WG.
• Participation in personnel safety systems‑oriented activities of EN-AA to gain hands‑on experience with the particularities of these kinds of installations.

Your Profile

• Previous professional experience in the electrical domain such as power converters, electrical networks, control systems, etc.
• Experience in safety and/or critical systems engineering.
• Assets
• Experience in the fire safety domain.
• Knowledge of radioactive environmental conditions and underground facilities.
• Initial experience in IEC 61508/61511 and EN 54 standards.
• Knowledge of the French language.

Skills

• Electrical engineering.
• Safety systems engineering.
• Quality management.
