Job Description

Your responsibilities

As an Electromechanical Technical Engineer you will join the EN-AA-CSE engineering team within our Engineering department (EN) to work on the Personnel Safety System Consolidation (PSS-CONS), whose scope is to refurbish the Large Hadron Collider (LHC) Personnel Safety Systems, reaching their end-of-life after 20 years of continuous operation. In particular, you will be working on the second generation of the SNIFFER system: a tailor-made system built specially to ensure personnel safety and asset protection inside the LHC Experiments. This system is integrated in Physics detector in LHC experimental underground areas, which represents a major challenge.

You will ensure the production of 220 modules of combined fire and gas detection, using air-sampling technology, up to their testing and commissioning, and further deployment on-site. You will join a dynamic project team already working on the re-engineering of the automation, mechanic and electronic parts of the project.

The role includes technical and organizational tasks:

  • Procurement of material and services, inside and outside CERN, necessary to the production of 220 new SNIFFER modules
  • Placing and following-up of orders
  • Follow up of manufacture and assembly phases, including the production of prototypes
  • Developing test procedures and defining: acceptance test, acceptance criteria, quality assurance
  • Carrying out integration tests of modules in Test Platform before deployment on-site
  • Technical test and acceptance tests on-site
  • Drawing up estimates and monitoring prices
  • Monitoring the progress of work and controlling quality, schedule and budget
  • Preparing project information, drafting and verifying technical documentation
  • Defining maintenance plans (repairs and modification) and spare parts policies
  • Follow up of on site works up to commissioning and handover to Operations
  • Participation to project and coordination meetings

Your profile

Skills and/or knowledge

  • Excellent team-working attitude
  • Previous professional experience on production, assembly, testing and commissioning

About us

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
