Founding Space-HTS Magnet Engineer

Zephyr Fusion; Vista (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Zephyr Fusion seeks an expert in HTS magnet systems to own the full lifecycle from architecture to test and flight integration. You will design, characterize, model, and test advanced HTS systems that will fly in space, collaborating with a multidisciplinary team to meet ambitious engineering goals.

This on-site role is based in Vista, CA, and requires US persons due to ITAR/export control restrictions. Join a fast-paced startup environment pushing frontier superconducting technologies for space

Qualifications

• 5+ years of experience in superconducting systems, including HTS REBCO based systems.
• Proficiency with finite-element and multi-physics simulation environments such as COMSOL, ANSYS, for nonlinear electromagnetic and thermal modeling.
• Ability to integrate simulation and experiment, including designing validation campaigns and refining models.
• Experience designing or evaluating superconducting structures under large Lorentz forces and cryogenic environments.
• Strong technical communication and collaboration across interdisciplinary teams.

Responsibilities

• Lead the development of Zephyr’s HTS magnet program, spanning conductor evaluation, coil architecture, electromagnetic design, thermal integration, mechanical robustness, and quench behavior.
• Build and maintain multi-physics modeling capabilities for superconducting systems, including coupled EM, thermal, and structural analyses.
• Lead the design, fabrication, instrumentation, and testing of HTS prototypes and integrated magnet hardware for flight-oriented architectures.
• Collaborate with plasma physics, thermal, mechanical, power systems, and mission engineering teams to translate requirements into practical magnet designs.
• Identify risks, guide design trade studies, and drive iterative development connecting simulation, experiment, and hardware.
• Help establish Zephyr’s long-term superconducting systems strategy, including manufacturing approaches and test infrastructure.
• Develop superconducting technologies for extreme environments including vacuum, launch constraints, and autonomous operation.
