Engineer in the Superconducting Radio-Frequency Section

Job Posting Organization:
CERN, the European Organisation for Nuclear Research, is a leading scientific research organization established to probe the fundamental structure of the universe. It employs physicists and engineers who utilize the world's largest and most complex scientific instruments to study the basic constituents of matter. CERN is known for its collaborative environment and operates in multiple countries, focusing on advancing knowledge in particle physics and related fields.

Job Overview:
The position of Engineer in the Superconducting Radio-Frequency Section at CERN involves significant contributions to the design and development of key RF components for the new 400 MHz Demonstrator Cryomodule. This role is crucial for advancing accelerator technology and supporting CERN's ambitious research programs. The successful candidate will work within the Accelerator Systems Department, which is responsible for the technical systems related to particle beams in CERN's accelerators. The role requires collaboration with multidisciplinary teams to innovate and improve RF power components, particularly focusing on the development of Fundamental Power Couplers (FPC) and High Order Mode (HOM) extraction couplers. The engineer will engage in mechanical design, simulations, and testing, contributing to the overall efficiency and reliability of the RF systems used in particle physics experiments.

Duties and Responsibilities:
The Engineer will be responsible for a variety of tasks including:

• Participating in the mechanical design of FPCs and HOM couplers, ensuring optimal material selection and manufacturing processes.
• Conducting coupled RF, thermal, and mechanical simulations to optimize designs across various operating conditions, from room temperature to cryogenic environments.
• Contributing to the design, construction, and operation of test stations for RF conditioning and high-power qualification.
• Overseeing the production and assembly of prototypes, including the preparation of specifications and quality control documentation.
• Supporting cryogenic qualification testing on both single cavities and full assemblies.
• Collaborating with internal and external teams, providing updates on progress, and presenting findings at workshops and conferences.

Required Qualifications:
Candidates must possess a Master's degree or PhD in electrical or mechanical engineering or a related field, along with relevant experience. They should demonstrate proficiency in mechanical and electrical engineering aspects of RF equipment, particularly in scientific instruments. Experience with electromagnetic simulation tools and mechanical and thermal finite element computations is essential. Additionally, candidates should have a proven track record in coordinating multidisciplinary projects, preparing technical specifications, and publishing research in international conferences.

Educational Background:
A Master's degree or PhD in electrical or mechanical engineering or a closely related field is required for this position. This educational background should provide a strong foundation in both theoretical and practical aspects of engineering as they relate to RF technologies and particle physics.

Experience:
Candidates should have demonstrated experience in mechanical and electrical engineering related to RF equipment, particularly in the context of scientific instruments. This includes experience with electromagnetic simulation tools, mechanical integration, prototyping, RF testing, and qualification processes. A history of coordinating multidisciplinary projects and preparing technical documentation is also necessary.

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

Additional Notes:
The position is a limited duration contract for 5 years, with the possibility of applying for an indefinite position under certain conditions. The working hours are set at 40 hours per week, and the role requires full onsite presence. The selected candidate will participate in regular stand-by duties, which may include nights, Sundays, and official holidays, and will work in radiation areas and underground installations. A valid driving license is required, and the candidate must obtain medical clearance due to occupational health risks associated with the position. The job grade is classified as 6-7.
