The Opportunity

We're looking for the Wavemakers of tomorrow.

Alphawave Semi enables tomorrow’s future by accelerating the critical data communication at the heart of our digital world – from seamless video streaming to AI to the metaverse and much more. Our technology powers product innovation in the most data-demanding industries today, including data centers, networking, storage, artificial intelligence, 5G wireless infrastructure, and autonomous vehicles. Customers partner with us for mission-critical data communication, our innovative technologies, and our proven track record. Together, we enable the next generation of digital technology.

Signal Integrity and Power Integrity (SI / PI) Engineer

We are seeking a highly skilled Signal Integrity (SI) and Power Integrity (PI) Engineer to join our team, focussing on high-speed electrical wireline systems. The successful candidate will play a critical role in designing, analyzing, and optimizing high-performance interconnects, ensuring signal and power integrity in high-speed package, chip-on-board, PCB, and cable designs.

We welcome candidates at various experience levels for this role. Our offers will align with the level during the interview assessment.

What You'll Do

• Conduct SI / PI simulations and analysis for high-speed interfaces (e.g. 106Gbps and higher PAM4 differential signaling)
• Develop simulation models based on electromagnetic analysis for PCB traces, vias, connectors, cables, IC packages, and photonics interconnects to ensure optimal SI / PI performance
• Perform frequency-domain and time-domain analysis, including S-parameters, impedance matching, crosstalk, return loss, insertion loss, and power supply AC noise analysis
• Work closely with cross-functional IC design teams to optimize high-speed interface layout floorplans to optimize SI / PI performance across a wide range of different interconnect technologies (e.g. C4 bump map for flip-chip BGA packages, uC4 bump map for silicon interposer chiplet designs, C4 bump map for chip-on-board pluggable modules)
• Define design guidelines and develop reference designs for high-speed interconnects and power distribution networks (PDN)
• Work closely with internal teams and external partners for hardware design, PCB layout, and manufacturing to ensure optimal SI / PI performance
• Validate SI / PI performance through lab measurements using oscilloscopes, vector network analyzers (VNAs), time-domain reflectometry (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 signal routing
• Drive improvements in design methodologies and best practices for high-speed electrical systems
