Senior Electrical Engineer – Dielectric Materials Development and Analysis

What You Will Be Doing:

You will contribute to the development, validation, and deployment of advanced ceramic and high-performance dielectric materials for extreme electrical, thermal, mechanical, and radiation environments. You will provide critical support to work spanning material and component design, prototyping, electrical characterization, qualification, and manufacturing scale-up. This onsite role is based at our Everett, WA, facility and reports to the Materials Science Manager, Metals and Dielectrics.

• Lead high-impact, multidisciplinary projects to develop and evaluate the electrical performance of advanced ceramic and dielectric materials for high-voltage operation under fusion-relevant conditions.
• Define electrical requirements, test methods, and acceptance criteria for insulating and resistive materials used in high-field magnet systems.
• Design and execute experiments to characterize properties such as dielectric strength, electrical resistivity, permittivity, dielectric loss, and performance under combined electrical, thermal, mechanical, and radiation loading.
• Translate material-level test results into actionable engineering requirements and design recommendations for Helion’s next-generation fusion systems.
• Serve as Helion’s subject-matter expert for dielectric materials and electrical insulation operating in a high-voltage environment, providing technical guidance across engineering and R&D teams.
• Own projects from initial concept and material selection through prototyping, design reviews, and qualification for production.
• Work effectively amid evolving requirements and technical uncertainty, balancing risk, rigor, and schedule to maintain program delivery.
• Advanced degree in Electrical Engineering, or a related field
• An extensive understanding of electrically insulating and dielectric materials, typically demonstrated by 5+ years of hands-on work
• Hands-on experience with electrical testing and materials characterization, including the design, execution, and interpretation of experiments.
• Demonstrated success developing or qualifying ceramic or dielectric materials for a commercial product or large, integrated engineering system, such as an engine, turbine, generator, magnet, or high-voltage assembly.
• Experience planning and leading R&D programs governed by defined milestones, technical reviews, and delivery schedules.
• Experience communicating material behavior and test results to multidisciplinary engineering teams and translating findings into design decisions.
• Up to 5% employer 401(k) match
• Annual wellness stipend
