• Architect innovative circuit board solutions for advanced secure processing, data storage, signal processing, DRFM, display, and extreme environment systems
• Design using cutting-edge technology including 400G+ Ethernet, PCIe Gen 5+, DDR5+ SDRAM, advanced fiber optics and video interfaces
• Champion design quality culture across programs through comprehensive reviews and proactive verification
• Lead strategic initiatives to advance board Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Test (DFT) across the organization
• Lead proposal development including system architecting, technical volume writing, and providing detailed BOE
• Provide mentorship and technical guidance to engineers at multiple levels

Required Qualifications:

• BS in Electrical Engineering or Computer Engineering (Master''s strongly preferred)
• Minimum 10 years of electrical engineering product development experience in board-level hardware design from concept to production
• Extensive experience designing highly complex embedded digital hardware products from concept to completion
• Proven track record of technical leadership on complex programs
• Experience developing advanced high-performance digital hardware, including next-generation interfaces, memory technologies, and high-speed interconnect architectures
• Expert-level understanding of signal integrity for very high-speed digital board design
• Significant experience leading proposals, developing schedule/cost estimates, and providing BOE at the program level
• This position requires you to access information that is subject to U.S. export regulations. You may only access such information if you are a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. government
