Staff Signal Integrity and Power Integrity Engineer (SI/PI)

We are seeking a highly skilled and visionary Staff Signal and Power Integrity (SI/PI) Engineer to join our advanced hardware engineering team. In this role, you will be the definitive technical expert responsible for ensuring the signal quality, timing, and power delivery robustness of our most complex, next-generation robotaxi electronic systems.

As a technical pillar within the organization, you will define overarching SI/PI architectures, establish company-wide simulation methodologies, guide electrical design and layout teams, and own the end-to-end sign-off for cutting-edge high-speed interfaces. In This Role, You Will Lead the SI/PI architecture and define constraints for next-generation, high-complexity, high-density printed circuit boards (PCBs) and overall system design.

Collaborate at an architectural level with hardware design, silicon vendors, PCB layout, and mechanical engineering teams to define layer stack-ups, routing strategies, component placement, and power delivery architectures. Analyze, optimize, and sign off on advanced high-speed serial links (PCIe, Ethernet, MIPI, GMSL) and memory interfaces (LPDDR).

Provide expert-level design guidance and validation for automotive-specific communication and audio protocols (A2B). Architect and conduct comprehensive Power Delivery Network (PDN) analysis, including DC IR drop, AC impedance modeling, and transient response analysis to ensure stable power delivery across complex multi-board systems. Drive the development of advanced SI/PI routing rules, simulation methodologies, automation scripts, and sign-off processes for the hardware engineering department.
