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

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 enthusiastic mechanical 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.

You will join:

  • The Beams Department (BE), which hosts the Groups responsible for beam generation, acceleration, diagnostics, controls and performance optimization.
  • The Radiofrequency group (BE-RF), responsible for the RF Acceleration and Transverse Damping Systems for CERN accelerators. Our team operates the RF systems of existing accelerators and participates in the design of future accelerators and upgrades of existing machines.
  • The Power Modules (BE-RF-PM) section, responsible for the design, operation and maintenance of large RF power plants and related infrastructure.

As a Mechanical Technician in the Power Amplifiers & Couplers, Modules Section, you will be part of a team working on Radio Frequency (RF) power devices with the aim of designing, assembling, maintaining and testing high power RF systems for CERN’s present accelerators and present plus future projects.

You will reinforce the team and be involve at all stages of the design, construction and tests of RF power devices. A senior technician will mentor you all along the projects.

After an initial training period, you will:

  • Produce out-of-the box designs using office-computing applications and liaise with CERN’s Main Workshop and with other relevant services at CERN and with external companies.
  • Participate in the operation and maintenance of existing systems.
  • Contribute to the development and prototyping of improved systems and their components for consolidation and upgrade of accelerators.
  • Participate in installation and commissioning of these systems.
  • Produce and manage the associated technical documentation and test reports.


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 (;
  • You have a Mechanical Technical Diploma or equivalent in Industrial Design of mechanical components (, and no more than four 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.

Technical competencies

  • Use of CAD (Catia).
  • Machining, operation and maintenance of RF components and systems.
  • Knowledge in metrology.
  • Design, contract follow-up and construction of mechanical devices.
  • Installation and tests of equipment.

Behavioural competencies

  • Solving problems: identifying, defining and assessing problems, taking action to address them; producing workable and timely solutions that meet requirements.
  • Working in teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities; supporting and acting in accordance with team decisions; accepting joint responsibility for team successes and shortcomings.
  • Learning and sharing knowledge: thinking “out of the box” and proposing fresh ideas, insights and methodologies; taking steps to expand knowledge in other areas of expertise beyond own field.
  • Achieving results: delivering prompt and efficient service taking into account customer needs; driving work/projects along and seeing them through to their conclusion.

Training value

This is a fantastic and unique chance to take part in the future of CERN! You will have the opportunity to become a skilled technician in various fields of expertise. This includes: CAD, conventional and modern machining, 3D fast prototyping, EBW, Laser welding, subcontracting follow-up, assembly, clean room tooling, vacuum technology, RF measurements.

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.

  • 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.
    – 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 31 January 2021.
