Junior Mechanical Engineer; SY-ABT-MDD--GRAE

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.

• 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.

• 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.

• Knowledge of structural analysis using finite element methods.
• Ability to work in an international multi‑disciplinary team with physicists, engineers, and technicians.
• Skills to prepare comprehensive technical documentation.
• Experience with FEA software is an advantage.
• Spoken and written English, with a commitment to learn French.

• You are a national of a CERN Member or Associate Member State.
