You will join the team working on oil-filled and cast-resin transformers for power converter applications. You will contribute to an ongoing renovation program aimed at progressively replacing oil-filled transformers with modern cast-resin transformers, driven by environmental considerations.
The role is hands-on and site-based, involving close interaction with equipment in operation. You will collaborate closely with a team of engineers, technicians, and external contractors for the integration of transformers within complex power converter systems. The role also offers you exposure to advanced low-voltage and medium-voltage power systems, and it provides you with many opportunities to further develop your practical and diagnostic skills in a high-level technical environment.
Your responsibilities
- Support installation and commissioning activities for new or refurbished transformers, including verification of protection, control, and interlock circuits.
- Contribute to the integration of transformers into upgraded power converter systems, ensuring correct connection and compatibility with control and protection equipment.
- Prepare basic 3D mechanical drawings or layouts for simple integration tasks when required.
- Contribute to technical documentation: electrical diagrams, test reports, installation procedures, and equipment inventory updates.
- Perform routine inspections, diagnostics and functional tests of oil-filled and cast-resin transformers.
- Carry out preventive and corrective maintenance activities on transformers.
Your profile
- Initial experience working in electrical installations (low and/or high voltage).
- Initial experience in operation and maintenance of electrical systems and equipment.
- Practical experience with troubleshooting and diagnostics of electrical installations is considered an asset.
- Experience in the field of power transformers is an advantage.
Skills
- Electrical safety awareness.
- Ability to read and understand electrical schematics and simple mechanical drawings.
- Familiarity with electrical measurements (multimeter, insulation tester, oscilloscope).
- Ability to work hands-on on site, in collaboration with technicians, engineers and contractors.
- Basic knowledge of 3D CAD tools is an asset.
- Spoken and written English, with a commitment to learn French.
Eligibility criteria:
- You are a national of a CERN Member or Associate Member State.
- By the application deadline, you have a maximum of two years of professional experience since graduation in Electricity (or a related field) and your highest educational qualification is a general secondary education diploma.
- You have never had a CERN fellow or graduate contract before.
- Applicants with a Bachelor's, Master's or PhD degree are not eligible.
