About the role

Key responsibilities & impact
  • Own the scientific charter and technical roadmap for the Magnets vertical
  • Lead research on phase stability, magnetocrystalline anisotropy, finite-temperature coercivity, and microstructure engineering across Fe- and Co-based intermetallic systems
  • Oversee translation of generative design outputs into a robust IP portfolio
  • Build, lead, and mentor a multidisciplinary team of research scientists, computational/ML scientists, and postdocs
  • Set the scientific bar, run technical reviews, and develop talent toward NewCo readiness
  • Specify and prioritize magnetism-aware LQM, data generation, and multi-scale modeling capabilities
  • Serve as senior scientific counterpart to Platform Engineering and DataGen Research
  • Lead scientific engagement with national laboratories and industrial partners
  • Translate partner constraints into scientific problems and deliver partner-grade results
  • Architect feedback loops between computational modeling and experimental lab validation to accelerate the DBTL cycle
  • Work with the commercial team to identify buyers, structure licensing agreements, and develop co-development partnerships
  • Author the external scientific narrative for updates, publications, conferences, and prospective investors
  • Protect scientific rigor and IP integrity

Requirements

What you’ll need
  • 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 the principal scientist, fellow, or director level
  • Demonstrated ability to translate first-principles, multi-scale, and ML-driven modeling into manufacturable magnet formulations
  • Experience coupling modeling to powder metallurgy, sintering, and heat-treatment processes
  • Track record of building and leading multidisciplinary scientific teams and shaping research roadmaps that deliver against external commitments
  • Outstanding external scientific presence, including publication and patent record
  • Ability to represent scientific work to senior government, defense, and industrial audiences
  • Hands-on experience with Fe-N, Mn-based, Sm-Co, or other rare-earth-lean permanent magnet systems and bulk processing challenges
  • Familiarity with lithography stages, vacuum pumps, precision actuators, or defense platforms
  • Experience with CHIPS Act, DOD, DOE, or other federally funded R&D programs
  • Knowledge of export-control and IP considerations
  • Prior involvement in NewCo formation, IP licensing, or scaling research IP into commercial manufacturing operations
  • Track record taking permanent magnet materials from concept through scale-up, qualification, and transfer into pilot or commercial manufacturing environments
  • Ability to translate system-level application requirements into composition, processing, and microstructure targets
  • Candidates cannot participate in foreign talent programs sponsored by China, Russia, Iran, or North Korea
