About this role

Fuse is seeking a Nuclear Engineer to develop and optimize radiation diagnostics and shielding systems for their fusion facility in Albuquerque. You will apply Monte Carlo simulations, conduct radiation analysis, and collaborate with physicists and engineers to advance diagnostic capabilities and ensure facility safety.

What you'll do

  • Implement and optimize neutron and gamma diagnostic systems for fusion experiments and validate detection performance
  • Conduct radiation-transport analysis using Monte Carlo tools like MCNP, Geant4, or FLUKA to improve system performance and safety
  • Analyze radiation data to support experimental campaigns, including source characterization and spectral unfolding
  • Design and optimize radiation shielding for mixed neutron and gamma environments
  • Develop and maintain radiation test environments for detector calibration and material testing
  • Support operational safety assessments, regulatory compliance, and meteorological radiation-dispersion evaluations

What they're looking for

  • Monte Carlo particle-transport simulations (MCNP, Geant4, FLUKA)
  • Neutron and gamma detection techniques
  • Radiation shielding and dose calculations
  • Radiation metrology and calibration
  • Programming (Python, MATLAB, C++)
  • Regulatory knowledge (NRC, CNSC, IAEA standards)
  • Data analysis and scientific computing
  • Fusion/fission facility experience (preferred)

Benefits

  • Medical, dental, and vision coverage
  • Flexible time off with no accrual tracking
  • 2 weeks paid time off built into year-end
  • Relocation assistance
  • Supportive leave of absence policies
  • Paid parental leave
