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. It operates in multiple countries and employs thousands of scientists and engineers from around the globe. CERN's mission is to probe the fundamental structure of the universe using the world's largest and most complex scientific instruments, studying the basic constituents of matter and the fundamental laws of nature. The organization is committed to diversity and employs a diverse workforce as a central part of its success.

Job Overview:
The Mechanical Engineer position at CERN involves the analysis and design of beam intercepting devices for the FCCee study. The successful candidate will collaborate with various teams, including P3 on the positron source, and will work on lepton and beamstrahlung dumps based on project priorities. The role also includes the development of radiation shielding for the FCCee main dipole system. The candidate will be responsible for defining, analyzing, and verifying complex numerical models to assess the performance of these devices under thermo-mechanical forces. This will require the use of Implicit and Explicit Finite Element solvers, such as LS-Dyna and ANSYS, to conduct analyses. Additionally, the candidate will perform Computational Fluid Dynamics and thermal analysis for components that require cooling, and engage in prototyping and testing activities to optimize mechanical components. The role demands a strong technical understanding of mechanical engineering principles and the ability to work effectively within multi-disciplinary, multi-cultural teams.

Duties and Responsibilities:
The duties and responsibilities of the Mechanical Engineer include:

• Defining, analyzing, and verifying complex numerical models to assess the performance of beam-intercepting devices under thermo-mechanical forces.
• Utilizing Implicit and Explicit Finite Element solvers, such as LS-Dyna and ANSYS, for conducting analyses.
• Performing Computational Fluid Dynamics and thermal analysis for components requiring cooling.
• Engaging in prototyping and testing activities aimed at developing and optimizing mechanical components.
• Commissioning material characterization studies and exploring manufacturing techniques in collaboration with internal and external partners.
• Proposing and implementing robust verification, validation, and quality control measures for designs and simulations.
• Documenting and articulating plans, specifications, and analysis work clearly and effectively.

Required Qualifications:
Candidates must demonstrate the ability to perform, interpret, and validate Finite Element and Computational Fluid Dynamics analysis. They should have practical experience with manufacturing processes, logistics of mass production, and process optimization. Strong organizational skills, attention to detail, and the ability to articulate and structure technical documents are essential. The candidate should also excel in working within multi-disciplinary, multi-cultural teams and possess strong communication skills in English, with a commitment to learn French.

Educational Background:
The position requires a professional background in Mechanical Engineering or a related field. Candidates should have either a Master's degree with 2 to 6 years of post-graduation professional experience or a PhD with no more than 3 years of post-graduation professional experience. Additionally, candidates must be nationals of a CERN Member or Associate Member State and should not have previously held a CERN fellow or graduate contract.

Experience:
The level of experience required for this position includes having a Master's degree with 2 to 6 years of relevant professional experience or a PhD with up to 3 years of experience in a related field. Candidates should have demonstrated practical experience in mechanical engineering principles and analysis techniques, particularly in Finite Element and Computational Fluid Dynamics.

Languages:
The mandatory language for this position is English, both spoken and written. Candidates are also expected to have a commitment to learn French, which is considered a good to have skill for this role.

Additional Notes:
The contract duration for this position is 24 months, with a possible extension of up to 36 months. The working hours are set at 40 hours per week, and the job is fully onsite. The target start date for this position is February 1, 202

• The role involves working in radiation areas and exposure to lead, thus requiring the selected candidate to obtain medical clearance before a contract offer is confirmed. The compensation includes a monthly stipend ranging from 6287 to 6911 Swiss Francs (net of tax), coverage by CERN's health scheme, and various allowances depending on individual circumstances. Additionally, employees receive 30 days of paid leave per year and opportunities for on-the-job and formal training, including in-house language courses.
