Senior Semiconductor Device Engineer

What You Will Be Doing:

You will drive the design and development of cutting-edge semiconductors for high-performance pulsed power systems used in Helion’s fusion generators. You will work in a fast-paced environment to develop, test, and implement high-reliability, high-efficiency switching components, with a strong emphasis on rapid development cycles. You will report directly to our Senior Manager of Electrical Engineering, and this is an onsite role located at our Everett, WA office.

You Will:

  • Spearhead efforts to gather and utilize requirements for switching components and apply them toward design of physical products 

  • Drive the design and development of novel pulsed power electronics components and systems, focusing on high-efficiency, high-reliability semiconductor solutions

  • Collaborate with cross-functional teams to ensure integration of electrical, mechanical, and physics-based principles in semiconductor development

  • Lead development cycles, including hands-on prototyping, small-scale testing, and large-scale performance validation

  • Conduct simulations, testing, and analysis to validate designs and iterate quickly using data-backed decision making

  • Stay informed on emerging semiconductor materials, device architectures, and industry trends

  • Document design processes, specifications, test results, and findings for continuous improvement and knowledge sharing

Required Skills:

  • Bachelor’s, Master’s, or higher degree in Electrical Engineering, Physics, or a related field

  • 8+ years of experience in power electronics and high voltage semiconductor design

  • Strong foundation in semiconductor physics, power electronics, and circuit design principles

  • Proven experience with rapid prototyping and development cycles in a high-tech environment

  • Background working with semiconductor fabricators to manufacture semiconductor devices 

  • Proficiency with simulation tools and test equipment for power electronics
