Job Overview:
The Electrical Technician position at CERN involves working on oil-filled and cast-resin transformers for power converter applications. The role is integral to an ongoing renovation program aimed at replacing traditional oil-filled transformers with modern cast-resin alternatives, driven by environmental considerations. This hands-on, site-based position requires close interaction with operational equipment and collaboration with a team of engineers, technicians, and external contractors. The technician will be involved in the integration of transformers within complex power converter systems, gaining exposure to advanced low-voltage and medium-voltage power systems. This role offers numerous opportunities for professional development, particularly in practical and diagnostic skills within a high-level technical environment.

Duties and Responsibilities:
The duties and responsibilities of the Electrical Technician include supporting installation and commissioning activities for new or refurbished transformers, verifying protection, control, and interlock circuits. The technician will contribute to the integration of transformers into upgraded power converter systems, ensuring correct connections and compatibility with control and protection equipment. Responsibilities also include preparing basic 3D mechanical drawings or layouts for simple integration tasks, contributing to technical documentation such as electrical diagrams, test reports, installation procedures, and equipment inventory updates. Routine inspections, diagnostics, and functional tests of oil-filled and cast-resin transformers are also part of the role, along with carrying out preventive and corrective maintenance activities on transformers.

Required Qualifications:
Candidates must have initial experience working in electrical installations, either low or high voltage, and some experience in the operation and maintenance of electrical systems and equipment. Practical experience with troubleshooting and diagnostics of electrical installations is considered an asset, and experience in the field of power transformers is advantageous. Candidates should possess electrical safety awareness, the ability to read and understand electrical schematics and simple mechanical drawings, and familiarity with electrical measurements using tools such as multimeters, insulation testers, and oscilloscopes. The ability to work hands-on on site in collaboration with technicians, engineers, and contractors is essential, and basic knowledge of 3D CAD tools is a plus.

Educational Background:
The position requires candidates to have a general secondary education diploma. By the application deadline, candidates should have a maximum of two years of professional experience since graduation in Electricity or a related field. It is important to note that applicants with a Bachelor's, Master's, or PhD degree are not eligible for this position.

Experience:
Candidates should have a maximum of two years of professional experience since graduation in a relevant field.
