Job Description

You will play a key role in ensuring that advanced simulation tools accurately reflect experimental behaviour of superconducting magnet systems. You will work closely with experimental test teams and simulation developers to validate, analyse and improve computational models, with particular emphasis on quench protection and ramp loss phenomena in Low-Temperature Superconductor (LTS) and High-Temperature Superconductor (HTS) magnets. You will contribute to design, performance evaluation and analysis of Quench Protection on several High Field Magnets (HFM) developed at CERN.

Your responsibilities

• Validate existing simulation tools against experimental data from superconducting magnet tests.
• Perform and assess simulations related to quench protection and ramp loss.
• Support the preparation of magnet test plans, including the definition of quench protection circuits.
• Analyse data collected during tests; produce clear visualisations, summaries, and technical reports.
• Provide structured feedback to simulation tool developers to improve model accuracy and usability.
• Contribute to studies and tests of both LTS and HTS magnets.
• This role includes team supervision responsibilities.

Your profile

• Experience with numerical simulations (e.g. finite-element, finite difference or multiphysics tools) and comparison with experimental data.
• Experience with experimental validation of numerical models.
• Experience with electrical circuits and/or cryogenic testing techniques.
• Experience with circuit simulations and analysis (e.g. PSPICE, XYCE).
• Experience with data analysis and visualisation (e.g. Python, MATLAB).
• Experience with superconducting magnets and accelerator technology would be an asset.

Skills

• Coding and scripting in Python or MATLAB for data analysis and visualisation.
• Basic understanding of superconductivity, magnet technology, and quench phenomena (LTS and/or HTS).
• Ability to work at the interface between simulations, experiments, and hardware testing.
• Good communication skills and ability to work effectively in a multidisciplinary and international team.
• Structured approach to problem solving and technical reporting.
• Spoken and written English, with a commitment to learn French.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Applied Physics, Electrical Engineering, Computational Physics (or a related field) and 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.
• You have never had a CERN fellow or graduate contract before.
