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 operates in multiple countries and is known for its collaborative environment that fosters innovation and scientific discovery. The organization is committed to diversity and inclusion, welcoming applications from all Member States and Associate Member States, and has a mission to push the frontiers of science and technology.

Job Overview:
The Mechanical Engineer position at CERN is a critical role that involves contributing to the forefront of nuclear science and medical research. The successful candidate will join a multidisciplinary team focused on the production of rare nuclei and radionuclides, which are essential for medical applications. This role requires a skilled and highly motivated individual who will be responsible for designing, operating, maintaining, and improving mechanical systems and target materials for radioactive ion beam production. The engineer will support the reliable operation of isotope separators and ensure compliance with safety regulations while handling unsealed radioactive materials. This position also involves leading planning and optimization of production activities, coordinating the medical isotope production process, and supporting laboratory activities related to nanomaterials development.

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

• Designing and operating mechanical systems and target materials for radioactive ion beam production at CERN-MEDICIS and ISOLDE.
• Supporting the reliable operation of CERN-MEDICIS isotope separators and associated infrastructure.
• Ensuring safe and compliant operation of laboratory installations, including glove boxes and hot cells, while adhering to radiation protection requirements.
• Leading the planning, documentation, monitoring, and optimization of production activities and workflows.
• Supporting activities in the nanomaterials laboratory and contributing to materials development, particularly in nuclear nanomaterials.
• Coordinating key steps in the medical isotope production process, from target preparation to quality control and shipment.
• Developing and documenting procedures, protocols, and safety measures related to the handling of radioactive materials.
• Operating complex scientific equipment, such as mass spectrometers, and ensuring their proper functioning.

Required Qualifications:
Candidates must possess a Master's degree or equivalent relevant experience in Mechanical, Material, Nuclear Engineering, or a related field. Additionally, proven experience in handling unsealed radioactive materials in controlled laboratory environments is essential. The ideal candidate should have expertise in quality assurance and control, system validation, project planning, risk assessment, and technical reporting. Experience in materials development, particularly with nanomaterials, and the ability to develop and document safety procedures are also required. Familiarity with operating complex scientific equipment is a plus, as is relevant experience from research, industry, or other regulated environments.

Educational Background:
A Master's degree or equivalent in Mechanical Engineering, Material Engineering, Nuclear Engineering, or a related field is required for this position. This educational background provides the necessary theoretical and practical knowledge to effectively perform the duties associated with the role.

Experience:
Candidates should have proven experience in handling unsealed radioactive materials in laboratory settings, as well as experience in quality assurance, system validation, and project planning. Relevant experience in materials development, particularly with nanomaterials, is highly desirable. Familiarity with operating complex scientific equipment and experience in regulated environments will be beneficial for applicants.

Languages:
Fluency in spoken and written English or French is mandatory, with a commitment to learn the other language. Proficiency in both languages will enhance communication within the diverse team at CERN.

Additional Notes:
This position is a limited duration contract for 5 years, with the possibility of extension up to 8 years and eligibility for an indefinite contract. The working hours are 40 hours per week, and the role is fully onsite. The selected candidate will participate in regular stand-by duties, including nights, Sundays, and official holidays, and may be required to work in radiation areas and underground installations. A valid driving license is necessary, and the candidate must obtain medical clearance due to occupational health risks associated with the position. The job grade is 6-7, and the reference for this position is SY-STI-2026-88-LD.
