Hazardous Material Decontamination Engineer (SCE-SAM-CE-2026-169-LD)

You will contribute to hazardous materials decontamination activities and civil engineering works and projects across CERN’s buildings and underground infrastructures. In this role, you manage the preparation, coordination and follow-up of interventions, working closely with engineers, technicians, consultants and contractors to ensure safe and compliant operations. You are involved in both planning and on-site activities, combining technical coordination with hands-on follow-up. You will join the Civil Engineering section (CE) within the Site Asset Management (SAM) Group. Act as the referent for pollutant-related works within the SCE-SAM group, managing the of hazardous materials decontamination activities at CERN. Act as contract manager for hazardous substances decontamination frame contracts, overseeing budget, quality, schedule and safety, and managing financial variations, claims and settlements with contractors. Serve as the referent of the civil engineering section for works and projects in technical galleries and the Proton Synchrotron complex facility. Manage project design steps (preliminary, concept design, developed project design, building permit, technical specifications and relevant documentation for tenders and execution design) in collaboration with internal CERN entities as well as the consultants and contractors appointed. Plan and manage the execution of construction and renovation projects, including coordination of various trades, utilisation of service and frame contracts and contract management, chairing site and coordination meetings, and monitoring cost, quality, schedule and safety until final acceptance. Ensure compliance with safety and environmental rules and promote a strong safety culture on work sites. Report on and document activities on a regular basis.

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. We are pushing the frontiers of science and technology. Our groundbreaking work brings together not only physicists but also a diverse range of professionals from engineering, technical, scientific, and administrative fields. Together, we foster an environment where innovation and collaboration thrive. Diversity is a core value of CERN since its foundation, and it remains central to our mission and continued success.
