The successful candidate will engage in analytical and finite-element studies of magnet windings, addressing aspects such as thermal behavior, cryogenic cooling, and mechanical performance. Additionally, the role involves supporting research and development (R&D) of conductors through studies and prototyping of both low- and high-temperature superconductors. The position also includes responsibilities related to the manufacturing, testing, and characterization of conductor samples, focusing on their superconducting, thermal, electrical, and mechanical properties.

Duties and Responsibilities:
The responsibilities of the Applied Physicist include conducting conceptual and finite-element studies of superconducting detector magnets, which encompass cold mass geometry, thermal behavior, cryogenic cooling, and mechanical performance. The role requires supporting the design and optimization of superconducting magnet systems for future particle detector applications. Participation in conductor R&D activities involving both low-temperature and high-temperature superconductors is essential. The candidate will assist with conductor prototyping, demonstrator manufacturing, and experimental testing campaigns. Additionally, characterizing conductor samples by evaluating their superconducting, thermal, electrical, and mechanical properties is a key duty. The role also includes team supervision responsibilities, ensuring effective collaboration and guidance within multidisciplinary teams.

Required Qualifications:
Candidates must have a background in superconductivity and superconducting technologies, with experience in superconducting magnet design and superconductor studies. Knowledge of materials science and characterization techniques is essential, along with familiarity with experimental physics and cryogenic systems. Proficiency in analytical and finite-element analysis methods is required, as well as skills in finite element analysis using commercial software such as Ansys and COMSOL. The ability to conduct experimental superconductivity campaigns, including cryogenic handling and operation of superconducting magnets, is crucial. Candidates should demonstrate effective collaboration in multidisciplinary team environments, independent work capabilities, and the ability to present and document study outcomes. Supervisory skills for students or junior contributors are also necessary.

Educational Background:
The position requires candidates to be nationals of a CERN Member or Associate Member State, with a professional background in Applied Physics or a related field. Applicants should possess 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. It is important that candidates have not previously held a CERN fellow or graduate contract.

Experience:
Candidates should have a professional background that aligns with the requirements of the position, specifically in superconductivity and superconducting technologies. Relevant experience in superconducting magnet design and superconductor studies is essential, along with practical experience in conducting analytical and finite-element studies. The ideal candidate will have a proven track record of working in multidisciplinary teams and managing tasks independently.

Languages:
Fluency in spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French, which is considered a valuable asset for the position.

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

• Candidates should be aware that this role involves exposure to electromagnetic fields under certain conditions, and medical clearance will be required before a contract offer is confirmed. The job reference is EP-CMS-IC-2026-99-GRAP, and the field of work is Applied Physics. The compensation includes a monthly stipend ranging from 6372 to 7004 Swiss Francs, which is tax-free, along with 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, a relocation package, and opportunities for on-the-job and formal training, including language classes.
