Mechanical Engineer in the Experimental Physics Department (EP), Detector Technology Group (DT), Fluidic Systems Section (FS).

You will join:

  • The Experimental Physics Department.
  • The Detector Technologies (DT) group, which participates in the development, construction and operation of particle detectors for experiments at CERN. This comprises detector consolidation and upgrade projects as well as infrastructure and services for experiments.
  • The Fluidic Systems Section, whose remit is to design, prototype, construct, commission, operate and maintain fluidic systems (gas and cooling) for detectors in CERN experiments. It has also the mandate to perform selective R&D in areas relevant to novel detector thermal management, gas systems and for the upgrade of the existing systems in view of higher detector performances and sustainable operation.


As a Mechanical Engineer in the Fluidic Systems Section, initially you will:

  • Take a leading role in the design process, supervising designers and external contractors in the 3D modelling execution and production of construction drawings both for the CO2 cooling and the gas projects.
  • Participate in the design, construction and testing of the next generation CO2 cooling systems for experiments.
  • Make thermo-mechanical calculations and fluid-dynamics calculations related to the projects under design.

At a later stage, you will:

  • Take responsibility for the industrialization process of the new CO2 cooling systems designed in the section.
  • Take active role in the collection of requirements and the fine tuning of the CO2 system design for one of the subdetectors, targeting the use of CO2 cooling in the phase II upgrade.
  • Participate in the commissioning and operation of CO2 cooling systems, including participation in the section stand-by duty service.


Master's degree or PhD, or equivalent relevant experience in the field of mechanical engineering, or equivalent.

Experience and competencies

The experience required for this post is:

  • Demonstrated experience in the design of fluidic systems (preferably CO2 cooling systems), 3D modelling and production of construction drawings.
  • Proven practice in mechanical and thermal calculations.
  • Initial experience in operation and maintenance of detector cooling systems.
  • Experience in coordinating projects involving academic and industrial partners.

The technical competencies required for this post are:

  • 3D & 2D technical drawing: CATIA v5 software as a preference, production of industrial standard construction drawings.
  • Thermal analysis and modelling.
  • Fluid-mechanics design.
  • Design of detector cooling systems with focus on low temperature CO2 cooling systems.
  • Maintenance and operation of detector cooling systems.

The behavioural competencies required for this post are:

  • Achieving results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind; delivering prompt and efficient service taking into account customer needs.
  • Learning and sharing knowledge: proposing ways to improve or streamline existing procedures, processes and methodologies.
  • Demonstrating flexibility: demonstrating openness to new ideas and situations.
  • Working in teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.

The language competencies required are:

  • Spoken and written English or French; ability to understand and speak the other language in professional contexts.
  • Ability to draw-up technical specifications and/or scientific reports and to make oral presentations in at least one of the two languages.
