Nuclear engineer Jobs in Oakland, CA

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.
