Environmental Engineer (Environmental Impact Assessment) (HSE-ENV-EC-2026-59-LD)

At CERN, the European Organisation 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.

You will contribute to the Future Circular Collider (FCC)—the organisation’s next flagship project—by overseeing and coordinating the environmental evaluation studies required for the authorisation process, including the environmental impact assessments for a new cross-border particle accelerator project, in accordance with French and Swiss regulatory requirements. This includes managing and monitoring contracts with consulting firms.

Functions

• Ensure technical and administrative coordination between the appointed consulting firms and guarantee the overall consistency of the environmental evaluation for both France and Switzerland.
• Ensure regulatory compliance of the environmental evaluation study in accordance with the French Environmental Code and Swiss legislation on environmental impact assessments (EIE).
