- Experience
- 7+ years of post-PhD experience.
- Education
- PhD in Materials Science, Physics, Chemistry, or a related discipline.
About the job
Leads the scientific strategy, team, and partner engagement for developing manufacturable high-performance permanent magnets with reduced reliance on rare earth elements.
What you'll do
- Set the Magnets vertical’s scientific charter and technical roadmap, and lead a multidisciplinary team.
- Guide magnetism-aware LQM, data generation, multi-scale modeling, and computational-to-experimental validation.
- Represent the program to external partners and support scientific publications, IP development, licensing, and commercial partnerships.
What they ask for
- PhD in Materials Science, Physics, Chemistry, or a related discipline, with deep specialization in magnetism, intermetallics, or hard magnetic materials.
- 7+ years of post-PhD experience leading scientific programs in magnetic materials, including significant industrial or national-lab leadership at principal scientist, fellow, or director level.
- Ability to translate first-principles, multi-scale, and ML-driven modeling into manufacturable magnet formulations, including powder metallurgy, sintering, and heat treatment.
- Track record of leading multidisciplinary teams and research roadmaps, with a strong publication and patent record and ability to represent work to senior audiences.
Nice to have
- Hands-on experience with Fe-N, Mn-based, Sm-Co, or other rare-earth-lean permanent magnet systems and bulk processing.
- Experience with federally funded R&D programs, NewCo formation, IP licensing, or scaling magnet research into manufacturing.
