Job Description

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.

ITAR REQUIREMENTS:

To conform to U.S. Government technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
