Electrical Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centers for scientific research. With a mission to uncover the fundamental structure of the universe, CERN operates in multiple countries and employs thousands of scientists, engineers, and support staff from diverse backgrounds. The organization is known for its collaborative environment, where innovation and teamwork are encouraged to tackle some of the most challenging scientific questions. CERN's facilities include the Large Hadron Collider, the world's largest and most powerful particle accelerator, and it continues to lead in advancements in particle physics and technology.

Job Overview:
The position of Electrical Engineer at CERN involves working on oil-filled and cast-resin transformers specifically designed for power converter applications. The role is crucial as it supports the transition from oil-filled transformers to cast-resin transformers for environmental sustainability. The engineer will be responsible for conducting design studies for power transformers and power converter systems, drafting technical specifications, managing the tendering process, overseeing industrial production, and ensuring quality management. Additionally, the role includes installation and commissioning activities for power transformers. The engineer will also develop simulation models for power converter systems to ensure the transformers are appropriately dimensioned for particle accelerator operations. This position requires a proactive approach to maintenance activities and the supervision of contractors, contributing to the overall efficiency and reliability of high-power converter systems ranging from 1 to 150 MW.

Duties and Responsibilities:
The Electrical Engineer will undertake a variety of responsibilities, including but not limited to: conducting electrical design studies and simulations for cast-resin transformers and their associated power converters; performing 3D mechanical design studies to integrate transformers into their designated pits; drafting technical specifications for cast-resin transformers and engaging in the procurement process; managing contracts and supervising contractor personnel; collaborating with manufacturers during the detailed design process of transformers; participating in the factory consolidation of large oil-filled transformers; conducting validation, type, and routine testing in the factory; assisting in the installation and commissioning of transformers; supervising the consolidation of transformer pits; and participating in the operation and maintenance of transformers.

Required Qualifications:
Candidates must possess a maximum of two years of professional experience since graduation in Electrical Engineering, Power Electronics, or a related field. The highest educational qualification required is either a Bachelor's or Master's degree. Applicants must not have previously held a CERN fellow or graduate contract, and those without a university degree or with a PhD are not eligible for this position.

Educational Background:
The position requires a Bachelor's or Master's degree in Electrical Engineering, Power Electronics, or a closely related field. This educational background is essential to ensure that candidates have the necessary theoretical knowledge and practical skills to perform the duties associated with the role effectively.

Experience:
Candidates should have relevant experience in power transformers and power electronics, particularly with high-power systems. This includes engineering, design, manufacturing, installation, commissioning, operation, and maintenance experience. Familiarity with design and modeling of high-power converter systems using tools such as MATLAB SIMULINK or PSIM is also required.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the other language being advantageous. This bilingual requirement is essential for effective communication within the diverse CERN community.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The job is fully onsite, and the target start date is March 1, 202
