Director - HTS Magnet Engineering

About Thea Energy:

Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.

Thea Energy is seeking a Director - HTS Magnet Engineering to provide strategic and technical leadership over the design, build, and test of high temperature superconducting ("HTS") magnets — the foundational component of Thea Energy’s planar coil stellarator. This role owns the magnet engineering roadmap end-to-end, manages engineering managers and cross-functional work streams, and partners with executive leadership to align magnet development with company-wide program milestones.

The Director will build organizational capability as the team scales rapidly, own key vendor and supply chain relationships, and represent magnet engineering in front of investors, partners, and technical stakeholders.

• Own the strategy, roadmap, and execution of the HTS magnet engineering program in alignment with company-wide fusion system milestones for Eos and Helios planar coil stellarator systems
• Ensure the magnet product roadmap drives synergy in our technology decisions between Eos and our power plant Helios
• Lead, develop, and scale a multi-level organization of engineering managers, engineers, and analysts
• Decompose and develop magnet specifications and technical requirements based on overall system design and performance goals of Eos
• Provide senior technical oversight of Multiphysics analyses, design tooling, and data infrastructure supporting magnet development for the Eos magnet systems
• Drive design-for-manufacturing strategy and oversee transition from first builds to scalable production
• Own key vendor and supplier relationships for magnet hardware, negotiating quotes and ensuring delivery against qualification requirements
• Direct tooling, manufacturing, and test infrastructure investments needed to support the magnet program
• Define and oversee execution of the magnet testing strategy, including qualification and reliability testing
• Own program-level tracking and reporting of progress, risk, budget, and milestones to executive leadership
• Represent magnet engineering to internal stakeholders, investors, external partners, and the broader fusion community
• Partner with adjacent engineering, physics, and operations teams to ensure magnet development is integrated with overall stellarator design

• 10+ years of engineering experience with magnets, cryogenics, vacuum systems, or transformer design, including significant experience leading engineering organizations
• Track record of managing and developing engineering managers and multi-disciplinary technical teams
• Deep technical fluency in CAD (Solidworks, CATIA, NX) and Multiphysics simulation (Ansys, COMSOL), sufficient to review and challenge team analyses
• Experience owning vendor and supply chain relationships for complex, custom hardware, including machining, welding, and fabrication
• Strong strategic thinking with the ability to translate system-level performance goals into an executable engineering roadmap
• Demonstrated ability to build and scale engineering organizations in a fast-paced, rapidly changing environment
• Comfortable setting aggressive deadlines and driving accountability across multiple teams and work streams
• Exceptional communication skills, with experience presenting to executives, investors, or external partners
• Innate desire to learn, innovate, and critique ideas — including one’s own and the organization’s
• At least a bachelor’s degree in physics, computer science, electrical engineering, mechanical engineering, materials engineering, or a related field; advanced degree strongly preferred
• Experience with magnetic confinement fusion, aerospace, medical devices, or other highly technical, regulated industries is preferred
