Job Description

As a Mechanical Engineer, you will join the Mechanics, Development and Design (MDD) section, where you will contribute to the design and development of advanced electromechanical systems for accelerator beam transfer across the entire CERN accelerator complex. Working alongside experienced engineers, physicists and technicians, you will help develop innovative equipment used in a world-leading scientific research environment.

Your responsibilities:

• Contribute to the conceptual design and development of mechanical and electromechanical systems.
• Produce engineering documentation, including 3D models, manufacturing drawings and Bills of Materials (BOMs).
• Support the manufacturing, assembly, testing and installation of equipment.
• Collaborate with physicists, engineers and technicians to translate conceptual requirements into practical engineering solutions.
• Participate in the development of innovative technologies for high-voltage pulsed power and accelerator systems.

Your profile:

• Initial experience designing mechanical components and assemblies using 3D CAD software (CATIA V5 is an advantage).
• Exposure to ISO GPS standards and BOM preparation.
• Hands-on experience in structural simulations using finite element analysis.
• Theoretical knowledge in mechanical behaviour of materials and production methods.
• Experience with additive manufacturing and 3D scanning would be an asset.

Skills:
