• Develop application notes, reference designs, training material, technical presentations, white papers, and other customer-facing or sales-enablement content.
• Support sales and field application engineering teams on opportunity qualification, design-in support, technical problem solving, and customer preparation.
• Operate effectively in a matrix organization and influence teams without direct authority.
• Travel to company locations, customer meetings, technical reviews, and industry events as needed, with anticipated travel up to approximately 25%.
• Other duties as assigned.

Experience and Education:

• B.S. in Electrical Engineering or related technical discipline is required; M.S. in Electrical Engineering, Power Electronics, Systems Engineering, Physics, or related field is preferred.
• 7+ years of relevant experience in systems or application engineering, electronics product design engineering, electrical systems, or related technical roles.
• Hands-on system-level development, integration, validation, testing, or troubleshooting experience is required.
• Experience with power electronics, circuit protection, switching, data center power, industrial electrical systems, aerospace/defense, or energy infrastructure applications is preferred.
• Demonstrated customer-facing or internal-customer-facing technical experience, such as applications engineering, technical marketing, product engineering, or strategic technical support.
• Ability to connect customer application requirements to product requirements, technical validation work, and practical business recommendations.
