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

Overview

Senior Signal Integrity and Power Integrity (SI / PI) Engineer at Alphawave Semi. We are looking for the Wavemakers of tomorrow. Alphawave Semi enables tomorrow’s future by accelerating critical data communication at the heart of the digital world – from video streaming to AI, the metaverse, and more. Our technology powers product innovation in data centers, networking, storage, artificial intelligence, 5G wireless infrastructure, and autonomous vehicles.

Role : Senior Signal Integrity and Power Integrity (SI / PI) Engineer – focus on high-speed electrical wireline systems. The successful candidate will design, analyze, and optimize high-performance interconnects and ensure signal and power integrity across high-speed package, chip-on-board, PCB, and cable designs.

What You’ll Do

• Conduct SI / PI simulations and analysis for high-speed interfaces (e.g., 106 Gbps and higher PAM4 differential signaling)
• Develop simulation models based on electromagnetic analysis for PCB traces, vias, connectors, cables, IC packages, and photonics interconnects
• Perform frequency-domain and time-domain analysis, including S-parameters, impedance matching, crosstalk, return loss, insertion loss, and power supply AC noise analysis
• Collaborate with cross-functional IC design teams to optimize high-speed interface layouts and floorplans across various interconnect technologies (e.g., C4 / uC4 bump maps)
• Define design guidelines and develop reference designs for high-speed interconnects and PDN
• Coordinate with internal teams and external partners for hardware design, PCB layout, and manufacturing to ensure SI / PI performance
• Validate SI / PI performance through lab measurements using oscilloscopes, VNAs, TDR, and other test equipment
• Identify and mitigate signal degradation issues such as reflections, jitter, and noise coupling
• Support package and PCB stack-up design, material selection, and layout optimization for high-speed routing
• Drive improvements in design methodologies and best practices for high-speed electrical systems
