Jobbeschreibung

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.

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.

Eligibility and closing date:

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
