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

JobsCloseBy Editorial Insights

This full-time onsite role with CERN’s EN‑AA‑CSE team supports the FCC study by delivering fire safety analysis and electrical safety design for underground facilities, coordinating with safety groups and contributing to studies. You will identify off-the-shelf and custom fire safety solutions, prepare cost estimates, and participate in FCC Working Groups. The ideal candidate has hands-on electrical engineering experience plus safety or critical-systems background, with knowledge of IEC 61508/61511 and EN 54 as assets; French is a plus. To apply, tailor your CV to fire safety and underground work, confirm eligibility (CERN Member/Associate Member State), and submit by 6 July 2026. Start 1 September 2026, onsite in Geneva; 24 months with possible extension; relocation and benefits provided.

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 Future Circular Collider study is developing designs for the next generation of higher-performance particle colliders that could follow the Large Hadron Collider (LHC). 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. In anticipation of a final decision and a Technical Design Report (TDR), the FCC study enters a reference design phase, where refinement of concepts will take place to allow rapid and smooth 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, and access shaft depths between 180 and 400 m, with eight surface sites and four experiments.

Your responsibilities

The role includes technical and organisational tasks:

• 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.

Would be considered as 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 French language.

Skills

• Electrical engineering.
• Safety systems engineering.
• Quality management.
• Team working and communication.
• Adaptability and anticipation.
• 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 Electrical Engineering (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.
