What You Will Be Doing:
You will play a key role in developing dielectric materials suited for high voltage components that maximize efficiency in the extreme environment of a nuclear fusion reactor. Specific responsibilities will include the development and evaluation of novel materials or the assessment and vetting of a wide range of emerging materials with a focus on their extended performance under radiation exposure. This onsite role is based at our Everett, WA, facility and reports to the Materials Science Manager, Metals and Dielectrics.
You Will:
Lead high impact and multi-disciplinary projects to develop new high-voltage dielectric insulating materials that can perform under applied high-voltage conditions in an advanced fusion generator
Lead testing campaigns to quantify the electrical properties and behavioral response limits of materials exposed to demanding conditions of heat, stress, and accumulated radiation damage
Perform comprehensive reviews of published research and development efforts in advanced high-voltage dielectric materials and distill the information into summaries for non-nuclear engineers
Operate in an environment with obstacles and changing requirements, balancing risks with rapid delivery requirements
Partner with other internal Helion teams, external vendors, national laboratories, and universities to establish pathways to extended capabilities
Develop a broad collaborative network and represent Helion at technical meetings and conferences
Required Skills:
An advanced degree and/or extensive understanding of electrically insulating and dielectric materials, typically demonstrated by a degree in materials science, electrical engineering, physics, nuclear engineering, or related disciplines
8+ years of industry-related experience, including proven results executing R&D and development projects (including design reviews) for a commercial product
Capability to plan and lead R&D efforts guided by a milestone schedule
The ideal candidate would have a bias for action, know how to execute with urgency and favor learning through rapid prototyping
Preferred Skills:
Experience with radiation effects testing and characterization
Proven results with the new product introduction from seed concepts to commercial deployment
Practical knowledge of multi-physics modeling for simulating microstructures and properties based on processing approaches and relevant operating environments
