Industrial Mechanical Drafter (EN-CV-DO-2025-128-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.

Introduction

The Engineering Department (EN) pushes forward the limits of technology so that physicists can carry out their research. Within the Cooling and Ventilation Group (CV) of the EN department, you will join the Design Office Section (DO), which is in charge of the creation of drawings, 3D models, bills of material for the different projects within the EN-CV group.

Are you a qualified and proactive technician, specialised in industrial cooling and ventilation systems? Contribute your skill and experience to a unique environment hosting some of the world’s most complex technical installations.

Join CERN’s Cooling and Ventilation Design Office team. Take part!

Functions

As an Industrial Mechanical Drafter in the EN-CV Design Office, you will:

• Make preliminary and detailed technical design studies (Process and Instrumentation Diagrams, 3D BIM Models) using a 3D computer-aided design (CAD) system for both new installations, as well as modifications of existing cooling, ventilation and industrial piping installations;
• Assist in compiling work description files based on project leaders’ specifications;
• Contribute in preparing technical specifications, market surveys, and call-for-tender documents;
• Review drawings and 3D Models of drafters from third-parties, and provide them with technical guidance and support;
• Carry out on site measurements on the existing installations (reverse engineering) to produce as-built documentation;
• Perform calculations for ventilation and industrial piping systems (pipes and ducts sizing, fans and pumps pre-selection), with the support of CERN design engineers;
• Check on site that work carried out meets the specified requirements in close collaboration with CERN engineers and work supervisors.

Higher technical diploma or equivalent relevant experience in the field of Mechanics / Electromechanics / Hydraulics / Aeraulics or a related field.

Experience:

• Demonstrated experience in carrying out complex design studies for large industrial cooling and ventilation plants;
• Proven experience in carrying out quantity estimates for industrial cooling stations and assembly hall ventilation within installation projects;
• Experience in low voltage electrical systems;
• Extensive experience in the use of Revit and AutoCAD; 
• Would be considered an asset: 
  • experience with CATIA v5 ; 
  • experience in creation of 3D scans, and in the processing of point clouds.

Technical competencies:

• Design and construction of HVAC plants, and networks;
• Design and construction of cooling water systems;
• Production of 2D drawings and 3D models;
• Integration of mechanical systems.

Behavioural competencies:

• Communicating effectively:
  • providing others with timely information;
  • ensuring that information, procedures and decisions are appropriately documented.
• Demonstrating flexibility:
  • readily accepting new tasks or work/projects;
  • adapting quickly and resourcefully to shifting priorities and requirements.
• Managing self:
  • working well autonomously;
  • taking on activities and tasks without prompting.
• Solving problems:
  • identifying, defining and assessing problems, taking action to address them;
  • adopting a pragmatic approach;
  • understanding the value of adopting generic rather than 'gold -plated' technical solutions.
• Working in teams:
  • working well in groups and readily fitting into a team;
  • participating fully and taking an active role in team activities.

Language skills:

Spoken and written English or French, with a commitment to learn the other language.

Eligibility and closing date:

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organisation. Employing a diverse workforce is central to our success. We welcome applications from all Member States and Associate Member States.

This vacancy will be filled as soon as possible, and applications should normally reach us no later than 23.07.2025 at 23:59 CEST.
