Principal Engineer

Job Description Overview :

Our team specializes in innovative electromagnetic-related signal integrity (SI) and power integrity (PI) system design. As we continue to provide extensive multi-physics SI / PI support to project teams, we are seeking experienced R&D professionals to join us and enhance the system performance of all ASUS product lines.

The candidate will be responsible for SI / PI simulations on ASUS product lines (Laptops, Desktops, Servers, Motherboards, Graphics Cards, Phones, IoT Devices, etc.

From the early design stage to mass production, the candidate will be expected to function both independently and collaborate across different functional teams (EE, Layout, etc.

to analyze simulation results and deliver recommendations and / or solutions to projects on schedule. The candidate is also responsible for research ing advanced electromagnetic and multi-physics technologies to help ASUS deliver differentiated products to the market.

Essential Duties and Responsibilities :

• Lead Signal Integrity (SI) and Power Integrity (PI) simulations for ASUS product lines, including laptops, desktops, servers, motherboards, graphics cards, phones, and IoT devices.
• Analyze SI and PI simulation outcomes, providing precise design recommendations to optimize system performance.
• Col laborate with project teams to resolve board stackup , component placement, and routing challenges from initial design stages to mass production.
• Enhance system architecture and implement design improvements across product lines to boost stability, performance, and reduce costs.
• Perform end-to-end channel SI correlation, between simulation and lab measurement s , for timing and eye-opening in high-speed serial links and memory interfaces.
• Perform whole Power Delivery Network (PDN) PI correlation, between simulations and lab measurements of impedance in frequency domain , current, and voltage in time domain .
• Research on advanced electromagnetic technologies and innovative system electrical architectures, standardiz e SI and PI design and analysis workflows with automation .
• Collaborate with industry partners, component vendors, and academic institutions to explore and integrate cutting-edge multi-physics technologies.
