Job Overview:
The Electrical Technician position at CERN involves working on oil-filled and cast-resin transformers for power converter applications. The role is hands-on and site-based, requiring close interaction with operational equipment. The technician will contribute to an ongoing renovation program aimed at replacing oil-filled transformers with modern cast-resin transformers, driven by environmental considerations. This position offers exposure to advanced low-voltage and medium-voltage power systems and provides opportunities to develop practical and diagnostic skills in a high-level technical environment. The technician will collaborate closely with engineers, technicians, and external contractors to integrate transformers within complex power converter systems, ensuring compatibility and correct connections with control and protection equipment.

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, prepare basic 3D mechanical drawings or layouts for simple integration tasks, and contribute to technical documentation such as electrical diagrams, test reports, installation procedures, and equipment inventory updates. Additionally, the technician will perform routine inspections, diagnostics, and functional tests of oil-filled and cast-resin transformers, as well as carry out preventive and corrective maintenance activities on transformers.

Required Qualifications:
Candidates must have initial experience working in electrical installations (low and/or high voltage) and initial 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 an asset.

Educational Background:
The educational background required for this position includes a general secondary education diploma. Candidates must be nationals of a CERN Member or Associate Member State and should have a maximum of two years of professional experience since graduation in Electricity or a related field. Applicants with a Bachelor's, Master's, or PhD degree are not eligible for this position.

Experience:
The position requires candidates to have a maximum of two years of professional experience since graduation in a relevant field.
