Company Description

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. Find out more on http://home.cern

Job Description

Introduction

The Accelerators and Technology Sector (ATS) is responsible for operating and exploiting the whole accelerator complex, particularly the LHC, and for developing new projects and technologies. The ATS comprises the Beams (“BE”), Engineering (EN), Systems (SY), and Technology (TE) departments.

The EN department provides CERN with the engineering competencies, infrastructure systems and technical coordination required for the design, installation, operation, maintenance and dismantling phases of the CERN accelerator complex and its experimental facilities.

The Accelerator Coordination & Engineering group (ACE) is in charge of coordinating the activities for the interventions and changes to the LHC and its injectors.

The mechanical engineer takes a leading role in the pre-design and 3D integration (a.k.a 3D coordination or spatial integration) of accelerators at CERN including major mechanical components, infrastructure and systems. He/she is also involved in producing and maintaining these 3D integration studies. One of the main current studies is the Future Circular Collider (FCC), which initiates the technical design phase.

The mechanical engineer also takes a leading role in preparing the documentation for the 3D integration studies of which he/she is in charge and for communicating it to all relevant parties, especially the civil engineering service.

The mechanical engineer can lead integration work packages for projects and associated teams of designers.

Functions

As Mechanical Engineer – 3D Integration for Accelerators, in the Engineering (EN) department*, Accelerator Coordination and Engineering (ACE) group, Integration section (INT), you will:

• Perform 3D integration studies, assembling models from design offices (mechanical, technical infrastructure, civil engineering) ensuring space reserved for transport and survey is available;
• Prepare and update the work package description of the 3D integration studies on projects for which you will be responsible, defining schedule, budget and resource requirements, establishing a list of tasks and deliverables and monitoring the progress of work;
• Lead a team of designers for the 3D integration studies of the various FCC configurations (e.g. electron-positron collider, hadron-hadron collider, low and high energy configurations) and/or areas (e.g. underground/surface, sites, etc.);
• Work in collaboration with the civil engineering service for dimensioning the civil works for surface and underground areas, pre-design or contribute to the design and 3D integration studies of accelerators components, with respect to the infrastructure (e.g. metallic structures, transport and handling components, etc.) and general services (e.g. HVAC, electrical systems, etc.) and produce and/or control drawings;
• Report and prepare the relevant documentation for reporting on the work packages for which he/she will be responsible;
• Present the results of the studies during workshops and conferences
