Nuclear Engineer
Fuse is on a mission to accelerate the world’s transition to fusion energy. Our core product is TITAN: an Impedance Matched Marx Generator (IMG). TITAN is the most efficient and powerful (TW) machine of its kind. Fusers have built and licensed Magical Unicorn and FAETON I, 2 novel pulsed power generators.
You are joining an early-stage fusion company. Please expect to wear different hats and take 0 to 1 ownership of objectives. Changing the world is hard but honorable and fulfilling. You should expect to work extremely hard to make a dent. This is not a regular job. Fusers are on a mission to change the world and get shit done.
We are seeking a Nuclear Engineer with expertise in particle transportation, Monte Carlo simulation, and radiation shielding to support our fusion facility. The ideal candidate will have a strong background in neutron and gamma detection, data analysis, and radiation test environments. Experience working in a combined neutron and gamma radiation environment, as found in fusion systems, is highly advantageous.
This role involves developing radiation models, optimizing shielding solutions, and ensuring radiation safety in a high-energy fusion environment. The candidate will work closely with physicists, engineers, and regulatory teams to enhance radiation transport simulations, detector performance, and measurement accuracy.
Key Responsibilities
Develop and apply Monte Carlo simulations (e.g., MCNP, Geant4, FLUKA) for particle transport, shielding, and dose assessment in a fusion facility.
Design and optimize radiation shielding for mixed neutron and gamma environments.
Conduct experimental validation of neutron and gamma detection systems.
Perform radiation transport analysis to improve system performance and safety.
Develop and maintain radiation test environments for detector calibration and material testing.
Support meteorological assessments related to radiation dispersion and environmental safety.
Analyze radiation data for operational safety, shielding effectiveness, and compliance with regulatory requirements.
Collaborate with multidisciplinary teams on fusion technology development and radiation safety initiatives.
Qualifications & Skills
Master’s or PhD in Nuclear Engineering, Physics, or a related field.
Strong experience in Monte Carlo particle transport simulations (MCNP, Geant4, FLUKA, etc.).
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++, etc.).
Familiarity with regulatory frameworks (CNSC, NRC, IAEA standards).
Preferred Qualifications
Experience working in a fusion/fission facilities or similar combined neutron-gamma radiation environment.
Background in high-energy neutron/Gamma transport and shielding.
Knowledge of advanced radiation detection technologies.
Additional Requirements
Must be able to travel and work extended hours/weekends as needed.
