Job summary

Fuse in California seeks a Nuclear Engineer to advance radiation diagnostics and shielding for our fusion research facility.

You will implement Monte Carlo simulations (MCNP, Geant4, FLUKA) and develop detector calibration environments while collaborating with physicists and engineers to push diagnostic capabilities and safety compliance.

The role requires a PhD or Master’s in a relevant field, strong coding in Python/MATLAB/C++, and willingness to travel and obtain security clearance as needed.

Qualifications

• Master’s or PhD in Nuclear Engineering, Physics, or a related field.
• Experience with Monte Carlo particle-transport simulations (MCNP/Geant4/FLUKA).
• Hands-on experience with neutron and gamma detection techniques.
• Knowledge of radiation shielding, dose calculations, and safety assessments.
• Experience in radiation metrology and calibration techniques.
• Proficiency in data analysis and programming (Python, MATLAB, C++).
• Familiarity with CNSC, NRC, and IAEA standards.

Responsibilities

• Implement and optimize neutron and gamma diagnostic systems for radiation characterization in fusion experiments.
• Analyze radiation data to support experiments, including source characterization and spectral unfolding.
• Perform radiation-transport analysis to improve system performance and safety.
• Develop and maintain radiation test environments for detector calibration and material testing.
• Develop and apply Monte Carlo simulations for particle transport, shielding, dose assessment, and detector performance.
• Design and optimize radiation shielding for mixed neutron and gamma environments.
• Support regulatory and environmental safety assessments for radiation dispersion.
