Company Description

Job Description

The 3D Integration Office, part of CERN's EN-ACE group, coordinates integration activities for the third Long Shutdown (LS3), a major programme shaping the future of the accelerator complex.

In this role, you will coordinate a multidisciplinary team of designers, oversee complex 3D integration studies, and drive continuous improvement of data quality processes. Working at the core of one of CERN's most ambitious engineering programmes, you will collaborate with diverse technical experts and contribute to the successful integration of advanced systems in a highly international environment.

Your responsibilities

  • Coordinate, monitor and follow up 3D integration studies supporting the third Long Shutdown (LS3) of the CERN accelerator complex.
  • Collaborate with multidisciplinary teams during on-site installation and maintenance activities to identify and resolve integration issues.
  • Prepare and maintain technical documentation, update project information in internal IT platforms (e.g. Track It, EDMS), and develop dashboards to support project monitoring and decision-making.
  • Create, update and maintain 3D models using CATIA V5 to ensure accurate and reliable integration data.
  • Contribute to improving the quality of CAD data within the PDM/PLM environment and support robust 3D integration validation workflows.
  • Help develop and standardise 3D integration processes, methodologies and best practices across the Integration Office.
  • Verify mechanical and magnetic references in close collaboration with the Layout and Configuration Management team.
  • Support the organisation and reporting of Integration Committee meetings, fostering effective communication and coordination between stakeholders.
  • Coordinate laser scanning activities with survey and scheduling teams, ensuring efficient planning, compliance with safety requirements and preparation of access authorisations.
  • Develop and maintain collaborative web workspaces to centralise information, facilitate knowledge sharing and strengthen communication within the Integration Office and with project stakeholders.
