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.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.


Job Description

Are you an electrical technician looking for a challenging professional experience to further your career?  If so, joining CERN’s TTE programme may very well give you that challenge. 

Within the Technology Department, the Cryogenic Group (CRG) is responsible for the design, construction, operation & maintenance of cryogenic systems for accelerators and detectors. Cryogenic instrumentation, including the cryogenic sensors, their cabling, and their often radiation hard electronics, is within this group falling under the Cryogenic laboratory and Instrumentation section (CI).

The work foresee for this position involves the consolidation, repair and commissioning of the measuring chains of the cryogenic system of the LHC machine, and includes the field work related with electrical wiring, the simulation of process variables  and the analysis of the distributed input/output electronics by using our computer interfaces. These interventions have to be performed on equipment distributed all around the 27 km circumference of the LHC tunnel.

Furthermore, CERN has several experimental and test facilities that involve a large array of cryogenic measurement techniques. The work in this field requires the understanding of various measurement techniques (fluid flow, pressure, temperature, etc) in order to select new equipment or to diagnose faulty instrumentation channels.

You will follow-up the ongoing work, guaranteeing the correct state of the existing cryogenic instrumentation channels, and shall validate the operational status of new cryogenic instrumentation channels.


  • To assure the integrity of the cryogenic instrumentation measurement chain;
  • To update documentation and create, whenever required, non-conformities reports
  • To participate actively in the development and repair of custom electronics
  • To participate in the operational tasks of CERN cryogenic facilities
  • To implement new measurement chains in accordance to the end-user requirements



In order to qualify for a place on the programme you will need to meet the following requirements:

  • You are a national of a CERN Member State or Associate Member State (https://home.cern/about/member-states);
  • You have an Electrical Technical Diploma in physical instrumentation or equivalent (careers.cern/ttediplomas), and no more than 4 years' relevant experience after finishing your diploma;
  • If you are currently studying, you are still eligible to apply, although you are expected to have obtained your qualification by the start of your appointment at CERN;
  • If you hold a BSc or MSc, you are not eligible. However you may be eligible for the Fellowship Programme.
  • You should have at least a working knowledge of English or French.


Specific skills required for this job:

  • Knowledge of :
    • measurement principles for flow, pressure and temperature
    • control environments for the diagnostics of smart instrumentation as found in modern control fieldbus networks
    • basic computer based programs such as Office, Word, Excel,…
    • LabView and Siemens Step 7/PDM software would be an advantage
  • Basic electronics design knowledge
  • Capability to apply strict Quality Assurance Procedures
  • Comfortable with manual tasks that involve wire and component soldering, wiring tools (crimping, cutting, etc.) and small machine tools
  • You shall have a valid driver’s licence.
Training Value:

You will gain experience in the commissioning of instrumentation channels, in the application of strict quality assurance procedures imposed by a system involving several thousands of acquisition channels and low noise techniques required by the low level of signals encountered in the cryogenic applications.

Valuable technical expertise will be acquired when participating in new developments, prototyping, production, commissioning and operation.

Furthermore, this work requires continuous interactions with different teams assuring a possibility to acquire communication skills with CERN its multicultural environment.


Additional Information

CERN would very much like to benefit from your expertise, commitment and passion. In return, CERN will provide you with:

  • An employment contract of one year, renewable for a second year; 
  • On-the-job and formal training at CERN as well as in-house language courses for English and/or French;
  • A monthly stipend of 4565 Swiss Francs per month (net of tax);
  • Coverage by CERN’s comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund;
  • Depending on your individual circumstances: an installation grant, family, child and infant allowances as well as travel expenses to and from Geneva;
  • 2,5 days of paid leave per month.

This is how you can apply. Here are few tips to start you off:

Here are few tips to start you off:

  • Be as specific as possible in the application fields “Education” and “Experience”.
  • We recommend you prepare your answers in Word or Notepad in advance, as once you start completing the application on Smartrecruiters, you have a limited time to submit it.
  • If you apply to more than one job, you will need to upload the documents for each application you submit.

Required documentation:

You will need the following documents, clearly labelled (e.g. “CV”, “Motivation letter”, “Academic transcript”, etc.) and in PDF format to complete your application:

  • A CV;
  • A scanned copy of your latest relevant qualification;
  • One reference letter (from a professor or previous employer) giving an overview of your academic and/or professional achievements. This should be as broad as possible.

Make sure you have all the documents needed to hand as you start your application, as once it is submitted, you will not be able to upload any documents or edit your application further. 
You may upload the reference letter yourself, whilst submitting your application, or through your referee via the link you will receive shortly after submitting your application.

All applications should normally reach us no later than 28.05.2020.
