Role overview

Pranos Fusion is seeking an exceptional Magnet Engineer to lead the design, fabrication oversight, and testing of high-temperature superconducting magnet systems for our fusion device. You will play a central role in one of the most technically demanding aspects of our fusion program - building high-field HTS coils that are reliable, manufacturable, and compatible with tokamak operational requirements.

Key responsibilities

  • Lead electromagnetic design of HTS magnet coils (TF, PF, CS) using FEM tools (COMSOL, Opera, or equivalent).
  • Specify and select REBCO or BSCCO HTS tape conductors; evaluate vendor qualification data.
  • Design mechanical structure for HTS coils: winding packs, impregnation schemes, support structures, and joints.
  • Develop and oversee winding, insulation, heat-treatment (if applicable), and impregnation processes.
  • Lead quench analysis and develop quench protection strategies tailored to HTS coil behavior.
  • Plan and execute cryogenic test campaigns, including ramp-to-design current, quench characterization, and joint resistance measurement.
  • Collaborate with electrical, cryogenic, and structural engineers to integrate magnet systems into the full device.
  • Track HTS conductor and magnet technology developments; contribute to the selection of next-generation conductor strategies.

Qualifications

  • Master's, or Ph.D. in Electrical Engineering, Physics, Applied Superconductivity, or Materials Science.
  • 5+ years of direct experience designing, building, or testing HTS or LTS superconducting magnets for fusion, accelerators, or MRI applications.
  • Hands-on experience with REBCO (e.g., CORC, Roebel, CICC) or BSCCO HTS conductors.
  • Proficiency in EM design software: COMSOL Multiphysics, Opera 3D, or similar FEM codes.
  • Strong understanding of HTS critical surface (Ic vs. B, T, strain), AC losses, and joint technology.
  • Experience with cryostat design and cryogenic test infrastructure for large magnet assemblies.
  • Demonstrated ability to lead multi-disciplinary engineering teams and manage external fabricators.

Preferred experience

  • Experience with no-insulation (NI) or metal-insulation (MI) HTS coil winding techniques.
  • Knowledge of demountable magnet joint technology for fusion tokamaks.
  • Background in neutron irradiation effects on HTS tape performance.
  • Experience at Commonwealth Fusion Systems, MIT PSFC, NHMFL, CERN, or a comparable HTS magnet program.
  • Familiarity with cost modelling and manufacturing scale-up of HTS conductor systems.

Pranos Fusion is an equal-opportunity employer. We celebrate diversity and are committed to a safe, inclusive workplace.
