Senior Geotechnical Engineer; SCE-PPM--LD

Senior Geotechnical Engineer (SCE-PPM--LD) Contract What you’ll do

You will join CERN’s civil engineering team working on the proposed Future Circular Collider (FCC), a 91 km circumference machine planned to be housed in an underground complex up to 500 metres below ground in the Geneva Basin. As a senior civil/geotechnical engineer with proven expertise in the design and construction of underground civil engineering structures – such as tunnels, shafts, caverns – you will be responsible for all geotechnical aspects of the design and potential construction of the extensive and complex civil engineering required for the FCC.

You will work on high‑value, technically complex projects, including the preparation and management of large‑scale contracts, while collaborating with other disciplines to develop robust civil engineering solutions.

• Undertake numerical studies to support the preliminary designs and optioneering studies for the FCC underground structures undertaken in‑house at CERN.
• Oversee and critically assess the geotechnical work carried out by external consultants, contractors and specialist advisors.
• Prepare the geotechnical technical specifications including a geotechnical baseline report (G ) required to support potential consultancy contracts related to the design and construction oversight of significant underground and surface structures envisaged for the FCC, including over 100 kilometres of tunnels, eight large space caverns, 12 shafts at depths up to 400 m and numerous other underground structures.
• Undertake the contract management of the consultancy and site investigation contracts to be put in place by CERN in order to obtain geotechnical data needed to inform subsequent design work.
• Manage the ongoing contract for external specialist support that CERN has with the ground engineering department of the University of Geneva.
• Work in close collaboration with the other members of the civil engineering team and provide them with expert support in the field of geotechnical engineering.

• Master’s degree or equivalent relevant experience in civil engineering and geotechnical engineering or a related field.
• Extensive experience within relevant fields of underground civil/geotechnical engineering.
• Proven experience in writing technical documentation for site investigations and design of underground structures.
• Design of underground structures.
• Knowledge of underground structure construction.
• Specification and follow‑up of technical aspects of a contract.
• Delivering high‑quality work on time and fulfilling expectations.
• Identifying, defining and assessing problems, taking action to address them, being open to original ideas and creative options, continually driving change by seeking new ways to improve outcomes.
• Adapting quickly and resourcefully to shifting priorities and requirements.
• Building and maintaining constructive and effective work relationships.
• Spoken and written English, with a commitment to learn French.
