Fuse is an embedded finance infrastructure company that enables businesses to integrate payments, cards, and banking features via APIs.
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.
