Thea Energy is building an economical and scalable fusion energy system utilizing arrays of mass manufacturable magnets and dynamic software controls. Backed by Prelude Ventures.
About the role
We are seeking a Lead HTS Magnet Systems Engineer to own the full lifecycle of our 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.
What they're looking for
- Superconducting Systems: Proven track record design and delivery of high-field (10T+) HTS cabled magnets or low-temperature (LTS) Cable-in-Conduit Conductors (CICC) for fusion applications
- Program Execution: Demonstrated ownership of major lifecycle milestones in complex megaprojects (e.g., W7x, JT60SA, KSTAR, ITER -scale setups, or commercial fusion ventures) with budget ownership $10M - $50M
- Failure Analysis & Test Operations: Hands-on leadership of full-scale magnet testing, cryogenic qualification (4.2K–20K), and post-test forensics
- Start-up experience: Has dealt with the demands of a fast-growing start-up
- Large-scale magnet manufacturing experience: Demonstrated experience with dealing with the challenges of forgings, composite insulation, solder potting in the 1-10m length scale and aware of the challenges
- Applied Superconductivity: REBCO 2G-HTS tape mechanics, strain limitations, current distribution, AC losses, and tape-to-cable joint architecture
