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.
Job Description
Introduction:
You will join a multidisciplinary team responsible for developing more efficient superconducting radiofrequency (SRF) cavities for future CERN accelerators. In this hands-on role, after dedicated training in the team you will contribute to the improvement of thin-film coating technologies through the design, fabrication, commissioning and operation of physical vapour deposition (PVD) equipment.
Functions:
- Design mechanical components and coating equipment using 3D CAD tools and produce the associated manufacturing and assembly drawings.
- Assemble, install, test, commission and operate physical vapour deposition coating systems and their associated equipment.
- Manufacture and modify metallic and ceramic components using conventional machining and computer numerical control (CNC)-based manufacturing techniques.
- Participate in coating activities, record operating parameters and document process procedures.
- Procure mechanical components for thin-film coating systems.
- Diagnose faults, carry out maintenance and implement mechanical improvements to existing coating systems.
- Apply the relevant safe.
Qualifications
- Technical certificate or general secondary education or equivalent relevant experience in the field of Mechanical Engineering or a related field.
Experience:
- Experience in conventional and CNC machining operations, particularly milling and turning.
- Experience using 3-dimensional computer-aided design 3D CAD software and interpreting technical drawings.
- Experience in the assembly and testing of ultra-high vacuum (UHV) systems would be an asset.
- Basic knowledge of vacuum thin-film coating techniques would be an asset.
Technical competencies:
- Assembly of mechanical structures and equipment.
- Manufacturing of mechanical parts.
- Installation and commissioning of vacuum systems.
- Production and analysis of thin-film coatings.
- Production of 2D drawings and 3D models.
Behavioural competencies:
- Working in Teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
- Solving Problems: identifying, defining and assessing problems, taking action to address them.
- Managing Self: working well autonomously; taking on activities and tasks without prompting.
- Achieving Results: objectively assessing and monitoring own work; regularly reporting on progress and advising of any changes in schedule or priorities.
- Communicating Effectively: expressing opinions, ideas and suggestions with conviction and in a logical/structured manner; keeping to the point.
Language skills:
- Spoken and written English, with a commitment to learn French.
