About the role

You are the lead Health Physicist on site, responsible for the technical radiation-protection program: source terms, shielding, instrumentation, dosimetry, surveys, and the operational decisions that flow from them. This is a hands-on lead role. Independently verify shielding designs developed by physics and engineering — geometry, source definition, tally choice, variance reduction, and uncertainty. Catch the errors before the concrete is poured.

What they're looking for

  • Master's degree in Health Physics, Nuclear Engineering, Radiological Sciences, Physics, or a related field
  • Certification by the American Board of Health Physics (CHP). Fuse will support maintenance of certification status
  • 5+ years of operational health physics experience in environments with non-trivial neutron and photon fields, with at least 2 years in a tritium-handling environment
  • Demonstrated production-grade proficiency with at least one major transport code: MCNP, MCNPX, PHITS, GEANT4, or FLUKA
  • Working knowledge of 10 CFR 835 or 10 CFR 20, DOE-STD-1098, DOE-HDBK-1129, and 20.3 NMAC
  • Hands-on experience with tritium bioassay programs, internal-dose assessment, and ICRP biokinetic models for HTO
More about this role

We are building one of the most potentially consequential companies of the century. Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win.

Independently verify shielding designs developed by physics and engineering — geometry, source definition, tally choice, variance reduction, and uncertainty. Catch the errors before the concrete is poured.

Run MCNP, PHITS, or GEANT4 transport calculations for the fusion generators, target chambers, beamlines, diagnostic ports, and shielded penetrations.

Build and maintain validated source-term models: D-T neutron yield and spectrum, capture and inelastic gammas, bremsstrahlung, and characteristic line emission.

Perform activation analysis on hardware in the neutron field and produce contact dose-rate vs. cool-down curves that operations can plan around.
