Principal Nuclear Materials Engineer
What You Will Be Doing:
You will play a key role in developing designs and materials suited for high-radiation environments, providing analysis and guidance to engineers on the behavior and performance of a wide range of materials under radiation exposure. In this onsite role, based at our Everett, WA office, you will report to the Director of Materials Science and collaborate closely with cross-functional teams to advance Helion’s mission.
You Will:
Advise engineering design decisions based on radiation effects (due to neutrons) on materials used within the radiation shield vault, e.g., metals used in magnet coils, dielectrics used for structure, and ceramics
Partner with neutronics engineers to predict dpa, analyze, model, and predict macroscopic effects on material properties including thermal conductivity, electrical resistivity, and mechanical strength. Assess system-level radiation risk
Oversee testing campaigns to quantify impact of radiation on material properties
Lead strategic projects to expand capabilities
Perform literature reviews on radiation effects on materials of interest and distill the information into summaries for non-nuclear engineers
Operate in an environment with obstacles and changing requirements. Balance risks without compromising the delivery
Partner with other internal Helion teams, external vendors, national laboratories, and universities to gather the required capabilities. Develop your network and represent Helion at technical meetings and conferences
Required Skills:
A professional understanding of radiation effects on materials, typically demonstrated by a degree in nuclear engineering, materials science, physics, or related discipline and 15+ years of hands-on work
15+ years of experience handling radioactive material
8+ years of experience working on non-aqueous corrosion and environmentally assisted degradation mechanisms (e.g., stress corrosion cracking, creep, accelerated fatigue)
8+ years of experience working on neutron interactions leading to e.g., material transmutation or helium bubble generation
8+ years of experience performing data analysis with a common coding language (Python, MATLAB, C++), data presentation, technical communication, and writing
Data presentation should include rigorous consideration of uncertainty and statistics
