Mechanical 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 over 2,500 employees and thousands of scientists from around the globe, CERN operates in multiple countries and is dedicated to pushing the frontiers of science and technology. The organization is renowned for its groundbreaking work in particle physics, and it fosters an environment where innovation and collaboration thrive. Diversity is a core value at CERN, and it remains central to its mission and continued success, ensuring that every contribution is valued and driving a shared sense of inclusion and purpose.

Job Overview:
The position involves joining a team of physicists and engineers focused on the development of novel detector concepts for the FCC-ee physics program. The successful candidate will take on the role of the main developer for an electromagnetic calorimeter design that utilizes innovative technology developed by collaborating institutes. This role requires interaction with physicists at CERN and other institutes to understand the key performance metrics of the calorimeter design. The candidate will also collaborate with CERN engineers and the FCC Machine-Detector Interface (MDI) group to navigate integration constraints related to the experimental cavern and collider elements. The position demands the development and optimization of detector geometry, including the production of detailed CAD models in collaboration with the physicist responsible for performance simulations. Additionally, the candidate will evaluate construction techniques for the calorimeter's mechanical elements, ensuring that both physics performance and structural requirements are met. The role also includes developing a concept for the overall supporting structure of the calorimeter and its integration within the overall detector mechanics, validating the concept through structural analysis, and overseeing the realization of a demonstrator to validate the design and selected technical solutions.

Duties and Responsibilities:

• Interact with physicists at CERN and collaborating institutes to understand the key figures of merit of a calorimeter design based on the proposed technology.
• Collaborate with CERN engineers and the FCC Machine-Detector Interface (MDI) group to understand integration constraints related to the experimental cavern and collider elements.
• Develop and optimize the detector geometry, producing sufficiently detailed CAD models in collaboration with the physicist in charge of the detector performance simulations.
• Evaluate construction techniques for the calorimeter mechanical elements, ensuring that both physics performance and structural requirements are met.
• Develop a concept for the overall supporting structure of the calorimeter and its integration within the overall detector mechanics, validating the concept through structural analysis.
• Oversee the realization of a demonstrator to validate the design and the selected technical solutions.

Required Qualifications:
Candidates must have a maximum of two years of professional experience since graduation in Mechanical Engineering or a related field. The highest educational qualification must be 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 Mechanical Engineering or a related field. This educational background is essential to ensure that candidates possess the necessary theoretical knowledge and practical skills required for the role.

Experience:
Candidates should have a maximum of two years of professional experience since graduation. This experience should ideally be in a relevant field, allowing the candidate to bring fresh perspectives and innovative ideas to the team while still being early in their career.

Languages:
Fluency in spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French. Proficiency in French will be considered an asset, enhancing communication within the diverse team at CERN.

Additional Notes:
The contract duration is set for 24 months, with the possibility of extension up to a maximum of 36 months. The job offers flexibility with a hybrid work model. The target start date for the position is April 1, 202
