Job summary

Thea Energy is seeking a Lead HTS Magnet Systems Engineer to own the full lifecycle of large-scale High-Temperature Superconducting (HTS) cabled magnet systems. You will bridge interdisciplinary electrical and mechanical domains, driving everything from early stage design trade studies and cable architectures (CICC stacked REBCO) to manufacturing, assembly, QA test and integration into the device.

You will drive end-to-end program ownership, specify high-current cabled HTS conductors, manage

Qualifications

• Experience designing high-field HTS cabled magnets for fusion applications.
• Ownership of major lifecycle milestones in megaprojects with budget ranges (e.g., $10M–$50M).
• Hands-on leadership of magnet testing, cryogenic qualification (4.2K–20K), and post-test forensics.

Responsibilities

• End-to-End Program Ownership: Lead system design reviews (CDR/PDR), subsystem qualification, site commissioning, and risk mitigation across multi-year fusion hardware projects.
• Cabled HTS Design: Specify and optimize high-current cabled HTS conductors, managing thermomechanical stresses, high-field Lorentz forces, and thermal quench propagation.
• Large-scale manufacturing: Specify and review designs in the 1-10m range and in the 10-100 Tonne range.
• Electro-Mechanical Integration: Direct coupling between high-current electrical power leads, quench detection systems, cryogenic cooling interfaces, and structural mechanical supports.
• Vendor & Lifecycle Management: Oversee technical deliverables for HTS tape/cable vendors, manufacturing facilities, and integration test platforms.
