  • Supervise EBW processes and provide technical support to the EBW team (training and welding developments);
  • Be the main technical interface with users for welding related aspects in design and methods; review engineering drawings and technical specifications; provide input on design, materials selection and standards/construction codes;
  • Set up and follow up a quality control system for the EBW activity (welding procedures qualification, NDT, documenting work, indicators);
  • Estimate production schedules to provide information for management decisions; be in charge of the fabrication planning for the EBW activities;
  • Participate in multidisciplinary projects, maintain close co-operation with the other Mechanical Engineering facilities CERN wide, be the Technical Responsible person for projects;
  • Establish a network and maintain contacts with specialised laboratories / firms worldwide;
  • Prepare technical reports and presentations.


Qualification required

Master's degree in the field of material science / mechanical engineering, or equivalent, and in addition an International Welding Engineer diploma (IWE).


Experience and competencies

The experience required for this post is:


  • Extensive experience as an electron beam welding engineer within a manufacturing environment;
  • Extensive experience in other joining technologies such as laser welding, vacuum brazing, arc welding;
  • Demonstrated experience in the fabrication of cryogenic, radiofrequency, ultra-high vacuum and pressure equipment.


The technical competencies required for this post are:


  • Manufacturing, fabrication technology and processes: personally operate EBW equipment for relevant applications;
  • Knowledge of metallic materials properties: in-depth knowledge of material science;
  • Welding: in-depth knowledge of welding standards, design and construction codes for pressure vessel (European and ASME);
  • Precision assembly and construction: good knowledge and practical experience of high-precision mechanical engineering;
  • 3D and 2D technical drawing: ability to read/interpret technical drawings and ISO tolerancing (dimensional and geometrical product specification standards), ability to draft technical drawings.


The behavioural competencies required for this post are:


  • Working in the interest of the Organization: behaving consistently with CERN's values and goals; demonstrating motivation for own work, being enthusiastic, involved and energetic in pursuing tasks;
  • Managing self: working well autonomously; taking on activities and tasks without prompting; taking initiative beyond regular tasks and making things happen; remaining objective, focussed and productive in a stressful environment; focusing on solutions rather than problems;
  • Achieving results: delivering high quality work on time and fulfilling expectations; being rigorous and producing quality results at first attempt; having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind;
  • Communicating effectively: expressing opinions, ideas and suggestions with conviction and in a logical/structured manner; keeping to the point; ensuring that information, procedures and decisions are appropriately documented;
  • Learning and sharing knowledge: keeping up-to-date with developments in own field of expertise and readily absorbing new information; sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer; creating or participating in forums to exchange experience, comparing techniques and learn from others.


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.
